CVE	Severity	Published▾	Status	Exploitation	Description
CVE-2026-35535	High	2026-04-03	Not applicable	No public exploit	In Sudo through 1.9.17p2 before 3e474c2, a failure of a setuid, setgid, or setgroups call, during a privilege drop before running the mailer, is not a fatal error and can lead to privilege escalation.
CVE-2024-45307	Critical	2024-09-03	Not applicable	No public exploit	SudoBot, a Discord moderation bot, is vulnerable to privilege escalation and exploit of the `-config` command in versions prior to 9.26.7. Anyone is theoretically able to update any configuration of the bot and potentially gain control over the bot's settings. Every version of v9 before v9.26.7 is affected. Other versions (e.g. v8) are not affected. Users should upgrade to version 9.26.7 to receive a patch. A workaround would be to create a command permission overwrite in the Database. A SQL statement provided in the GitHub Security Advisor can be executed to create a overwrite that disallows users without `ManageGuild` permission to run the `-config` command. Run the SQL statement for every server the bot is in, and replace `<guild_id>` with the appropriate Guild ID each time.
CVE-2023-7090	High	2023-12-23	Not applicable	No public exploit	A flaw was found in sudo in the handling of ipa_hostname, where ipa_hostname from /etc/sssd/sssd.conf was not propagated in sudo. Therefore, it leads to privilege mismanagement vulnerability in applications, where client hosts retain privileges even after retracting them.
CVE-2023-42465	High	2023-12-22	Not applicable	No public exploit	Sudo before 1.9.15 might allow row hammer attacks (for authentication bypass or privilege escalation) because application logic sometimes is based on not equaling an error value (instead of equaling a success value), and because the values do not resist flips of a single bit.
CVE-2023-42456	High	2023-09-21	Not applicable	No public exploit	Sudo-rs, a memory safe implementation of sudo and su, allows users to not have to enter authentication at every sudo attempt, but instead only requiring authentication every once in a while in every terminal or process group. Only once a configurable timeout has passed will the user have to re-authenticate themselves. Supporting this functionality is a set of session files (timestamps) for each user, stored in `/var/run/sudo-rs/ts`. These files are named according to the username from which the sudo attempt is made (the origin user). An issue was discovered in versions prior to 0.2.1 where usernames containing the `.` and `/` characters could result in the corruption of specific files on the filesystem. As usernames are generally not limited by the characters they can contain, a username appearing to be a relative path can be constructed. For example we could add a user to the system containing the username `../../../../bin/cp`. When logged in as a user with that name, that user could run `sudo -K` to clear their session record file. The session code then constructs the path to the session file by concatenating the username to the session file storage directory, resulting in a resolved path of `/bin/cp`. The code then clears that file, resulting in the `cp` binary effectively being removed from the system. An attacker needs to be able to login as a user with a constructed username. Given that such a username is unlikely to exist on an existing system, they will also need to be able to create the users with the constructed usernames. The issue is patched in version 0.2.1 of sudo-rs. Sudo-rs now uses the uid for the user instead of their username for determining the filename. Note that an upgrade to this version will result in existing session files being ignored and users will be forced to re-authenticate. It also fully eliminates any possibility of path traversal, given that uids are always integer values. The `sudo -K` and `sudo -k` commands can run, even if a user has no sudo access. As a workaround, make sure that one's system does not contain any users with a specially crafted username. While this is the case and while untrusted users do not have the ability to create arbitrary users on the system, one should not be able to exploit this issue.
CVE-2023-28487	Medium	2023-03-16	Outside Waratek scope	No public exploit	Sudo before 1.9.13 does not escape control characters in sudoreplay output.
CVE-2023-28486	Medium	2023-03-16	Outside Waratek scope	No public exploit	Sudo before 1.9.13 does not escape control characters in log messages.
CVE-2023-27320	High	2023-02-28	Not applicable	No public exploit	Sudo before 1.9.13p2 has a double free in the per-command chroot feature.
CVE-2022-43995	High	2022-11-02	Not applicable	No public exploit	Sudo 1.8.0 through 1.9.12, with the crypt() password backend, contains a plugins/sudoers/auth/passwd.c array-out-of-bounds error that can result in a heap-based buffer over-read. This can be triggered by arbitrary local users with access to Sudo by entering a password of seven characters or fewer. The impact could vary depending on the system libraries, compiler, and processor architecture.
CVE-2021-23240	High	2021-01-12	Outside Waratek scope	No public exploit	selinux_edit_copy_tfiles in sudoedit in Sudo before 1.9.5 allows a local unprivileged user to gain file ownership and escalate privileges by replacing a temporary file with a symlink to an arbitrary file target. This affects SELinux RBAC support in permissive mode. Machines without SELinux are not vulnerable.
CVE-2021-23239	Low	2021-01-12	Outside Waratek scope	No public exploit	The sudoedit personality of Sudo before 1.9.5 may allow a local unprivileged user to perform arbitrary directory-existence tests by winning a sudo_edit.c race condition in replacing a user-controlled directory by a symlink to an arbitrary path.
CVE-2019-19234	High	2019-12-19	Not applicable	No public exploit	In Sudo through 1.8.29, the fact that a user has been blocked (e.g., by using the ! character in the shadow file instead of a password hash) is not considered, allowing an attacker (who has access to a Runas ALL sudoer account) to impersonate any blocked user. NOTE: The software maintainer believes that this CVE is not valid. Disabling local password authentication for a user is not the same as disabling all access to that user--the user may still be able to login via other means (ssh key, kerberos, etc). Both the Linux shadow(5) and passwd(1) manuals are clear on this. Indeed it is a valid use case to have local accounts that are _only_ accessible via sudo and that cannot be logged into with a password. Sudo 1.8.30 added an optional setting to check the _shell_ of the target user (not the encrypted password!) against the contents of /etc/shells but that is not the same thing as preventing access to users with an invalid password hash
CVE-2019-19232	High	2019-12-19	Not applicable	No public exploit	In Sudo through 1.8.29, an attacker with access to a Runas ALL sudoer account can impersonate a nonexistent user by invoking sudo with a numeric uid that is not associated with any user. NOTE: The software maintainer believes that this is not a vulnerability because running a command via sudo as a user not present in the local password database is an intentional feature. Because this behavior surprised some users, sudo 1.8.30 introduced an option to enable/disable this behavior with the default being disabled. However, this does not change the fact that sudo was behaving as intended, and as documented, in earlier versions
CVE-2019-18684	High	2019-11-04	Not applicable	No public exploit	Sudo through 1.8.29 allows local users to escalate to root if they have write access to file descriptor 3 of the sudo process. This occurs because of a race condition between determining a uid, and the setresuid and openat system calls. The attacker can write "ALL ALL=(ALL) NOPASSWD:ALL" to /proc/#####/fd/3 at a time when Sudo is prompting for a password. NOTE: This has been disputed due to the way Linux /proc works. It has been argued that writing to /proc/#####/fd/3 would only be viable if you had permission to write to /etc/sudoers. Even with write permission to /proc/#####/fd/3, it would not help you write to /etc/sudoers
CVE-2005-4890	High	2019-11-04	Not applicable	No public exploit	There is a possible tty hijacking in shadow 4.x before 4.1.5 and sudo 1.x before 1.7.4 via "su - user -c program". The user session can be escaped to the parent session by using the TIOCSTI ioctl to push characters into the input buffer to be read by the next process.
CVE-2016-7076	High	2018-05-29	Not applicable	No public exploit	sudo before version 1.8.18p1 is vulnerable to a bypass in the sudo noexec restriction if application run via sudo executed wordexp() C library function with a user supplied argument. A local user permitted to run such application via sudo with noexec restriction could possibly use this flaw to execute arbitrary commands with elevated privileges.
CVE-2015-8239	High	2017-10-10	Not applicable	No public exploit	The SHA-2 digest support in the sudoers plugin in sudo after 1.8.7 allows local users with write permissions to parts of the called command to replace them before it is executed.
CVE-2017-1000368	High	2017-06-05	Not applicable	No public exploit	Todd Miller's sudo version 1.8.20p1 and earlier is vulnerable to an input validation (embedded newlines) in the get_process_ttyname() function resulting in information disclosure and command execution.
CVE-2014-9680	Low	2017-04-24	Not applicable	No public exploit	sudo before 1.8.12 does not ensure that the TZ environment variable is associated with a zoneinfo file, which allows local users to open arbitrary files for read access (but not view file contents) by running a program within an sudo session, as demonstrated by interfering with terminal output, discarding kernel-log messages, or repositioning tape drives.
CVE-2016-7032	High	2017-04-14	Not applicable	No public exploit	sudo_noexec.so in Sudo before 1.8.15 on Linux might allow local users to bypass intended noexec command restrictions via an application that calls the (1) system or (2) popen function.
CVE-2014-0106	Medium	2014-03-11	Not applicable	No public exploit	Sudo 1.6.9 before 1.8.5, when env_reset is disabled, does not properly check environment variables for the env_delete restriction, which allows local users with sudo permissions to bypass intended command restrictions via a crafted environment variable.
CVE-2013-2777	Medium	2013-04-08	Not applicable	No public exploit	sudo before 1.7.10p5 and 1.8.x before 1.8.6p6, when the tty_tickets option is enabled, does not properly validate the controlling terminal device, which allows local users with sudo permissions to hijack the authorization of another terminal via vectors related to a session without a controlling terminal device and connecting to the standard input, output, and error file descriptors of another terminal. NOTE: this is one of three closely-related vulnerabilities that were originally assigned CVE-2013-1776, but they have been SPLIT because of different affected versions.
CVE-2013-2776	Medium	2013-04-08	Not applicable	No public exploit	sudo 1.3.5 through 1.7.10p5 and 1.8.0 through 1.8.6p6, when running on systems without /proc or the sysctl function with the tty_tickets option enabled, does not properly validate the controlling terminal device, which allows local users with sudo permissions to hijack the authorization of another terminal via vectors related to connecting to the standard input, output, and error file descriptors of another terminal. NOTE: this is one of three closely-related vulnerabilities that were originally assigned CVE-2013-1776, but they have been SPLIT because of different affected versions.
CVE-2013-1776	Medium	2013-04-08	Not applicable	No public exploit	sudo 1.3.5 through 1.7.10 and 1.8.0 through 1.8.5, when the tty_tickets option is enabled, does not properly validate the controlling terminal device, which allows local users with sudo permissions to hijack the authorization of another terminal via vectors related to connecting to the standard input, output, and error file descriptors of another terminal. NOTE: this is one of three closely-related vulnerabilities that were originally assigned CVE-2013-1776, but they have been SPLIT because of different affected versions.
CVE-2012-3440	Medium	2012-08-08	Not applicable	No public exploit	A certain Red Hat script for sudo 1.7.2 on Red Hat Enterprise Linux (RHEL) 5 allows local users to overwrite arbitrary files via a symlink attack on the /var/tmp/nsswitch.conf.bak temporary file.
CVE-2012-2337	High	2012-05-18	Not applicable	No public exploit	sudo 1.6.x and 1.7.x before 1.7.9p1, and 1.8.x before 1.8.4p5, does not properly support configurations that use a netmask syntax, which allows local users to bypass intended command restrictions in opportunistic circumstances by executing a command on a host that has an IPv4 address.
CVE-2011-0008	Medium	2011-01-20	Not applicable	No public exploit	A certain Fedora patch for parse.c in sudo before 1.7.4p5-1.fc14 on Fedora 14 does not properly interpret a system group (aka %group) in the sudoers file during authorization decisions for a user who belongs to that group, which allows local users to leverage an applicable sudoers file and gain root privileges via a sudo command. NOTE: this vulnerability exists because of a CVE-2009-0034 regression.
CVE-2011-0010	Medium	2011-01-18	Not applicable	No public exploit	check.c in sudo 1.7.x before 1.7.4p5, when a Runas group is configured, does not require a password for command execution that involves a gid change but no uid change, which allows local users to bypass an intended authentication requirement via the -g option to a sudo command.
CVE-2010-2956	Medium	2010-09-10	Not applicable	No public exploit	Sudo 1.7.0 through 1.7.4p3, when a Runas group is configured, does not properly handle use of the -u option in conjunction with the -g option, which allows local users to gain privileges via a command line containing a "-u root" sequence.
CVE-2010-1646	Medium	2010-06-07	Not applicable	No public exploit	The secure path feature in env.c in sudo 1.3.1 through 1.6.9p22 and 1.7.0 through 1.7.2p6 does not properly handle an environment that contains multiple PATH variables, which might allow local users to gain privileges via a crafted value of the last PATH variable.
CVE-2010-1163	Medium	2010-04-16	Not applicable	No public exploit	The command matching functionality in sudo 1.6.8 through 1.7.2p5 does not properly handle when a file in the current working directory has the same name as a pseudo-command in the sudoers file and the PATH contains an entry for ".", which allows local users to execute arbitrary commands via a Trojan horse executable, as demonstrated using sudoedit, a different vulnerability than CVE-2010-0426.
CVE-2010-0427	Medium	2010-02-25	Not applicable	No public exploit	sudo 1.6.x before 1.6.9p21, when the runas_default option is used, does not properly set group memberships, which allows local users to gain privileges via a sudo command.
CVE-2009-0034	High	2009-01-30	Not applicable	No public exploit	parse.c in sudo 1.6.9p17 through 1.6.9p19 does not properly interpret a system group (aka %group) in the sudoers file during authorization decisions for a user who belongs to that group, which allows local users to leverage an applicable sudoers file and gain root privileges via a sudo command.
CVE-2007-3149	High	2007-06-11	Not applicable	No public exploit	sudo, when linked with MIT Kerberos 5 (krb5), does not properly check whether a user can currently authenticate to Kerberos, which allows local users to gain privileges, in a manner unintended by the sudo security model, via certain KRB5_ environment variable settings. NOTE: another researcher disputes this vulnerability, stating that the attacker must be "a user, who can already log into your system, and can already use sudo."
CVE-2006-0151	High	2006-01-09	Not applicable	No public exploit	sudo 1.6.8 and other versions does not clear the PYTHONINSPECT environment variable, which allows limited local users to gain privileges via a Python script, a variant of CVE-2005-4158.
CVE-2005-2959	Medium	2005-10-25	Not applicable	No public exploit	Incomplete blacklist vulnerability in sudo 1.6.8 and earlier allows local users to gain privileges via the (1) SHELLOPTS and (2) PS4 environment variables before executing a bash script on behalf of another user, which are not cleared even though other variables are.
CVE-2005-1993	Low	2005-06-20	Not applicable	No public exploit	Race condition in sudo 1.3.1 up to 1.6.8p8, when the ALL pseudo-command is used after a user entry in the sudoers file, allows local users to gain privileges via a symlink attack.
CVE-2005-1831	High	2005-05-31	Not applicable	No public exploit	Sudo 1.6.8p7 on SuSE Linux 9.3, and possibly other Linux distributions, allows local users to gain privileges by using sudo to call su, then entering a blank password and hitting CTRL-C. NOTE: SuSE and multiple third-party researchers have not been able to replicate this issue, stating "Sudo catches SIGINT and returns an empty string for the password so I don't see how this could happen unless the user's actual password was empty.
CVE-2005-1119	Low	2005-05-02	Not applicable	No public exploit	Sudo VISudo 1.6.8 and earlier allows local users to corrupt arbitrary files via a symlink attack on temporary files.
CVE-2004-1051	High	2005-03-01	Not applicable	No public exploit	sudo before 1.6.8p2 allows local users to execute arbitrary commands by using "()" style environment variables to create functions that have the same name as any program within the bash script that is called without using the program's full pathname.
CVE-1999-1496	Low	1999-06-08	Not applicable	No public exploit	Sudo 1.5 in Debian Linux 2.1 and Red Hat 6.0 allows local users to determine the existence of arbitrary files by attempting to execute the target filename as a program, which generates a different error message when the file does not exist.

Medium

2011-01-18

Not applicable

No public exploit

check.c in sudo 1.7.x before 1.7.4p5, when a Runas group is configured, does not require a password for command execution that involves a gid change but no uid change, which allows local users to bypass an intended authentication requirement via the -g option to a sudo command.

CVE-2010-2956

Medium

2010-09-10

Not applicable

No public exploit
