CVE Severity Published▾ Status Exploitation Description
CVE-2021-36369 High 2022-10-12 Not applicable No public exploit An issue was discovered in Dropbear through 2020.81. Due to a non-RFC-compliant check of the available authentication methods in the client-side SSH code, it is possible for an SSH server to change the login process in its favor. This attack can bypass additional security measures such as FIDO2 tokens or SSH-Askpass. Thus, it allows an attacker to abuse a forwarded agent for logging on to another server unnoticed.
CVE-2020-36254 High 2021-02-25 Not applicable No public exploit scp.c in Dropbear before 2020.79 mishandles the filename of . or an empty filename, a related issue to CVE-2018-20685.
CVE-2019-12953 Medium 2020-12-30 Not applicable No public exploit Dropbear 2011.54 through 2018.76 has an inconsistent failure delay that may lead to revealing valid usernames, a different issue than CVE-2018-15599.
CVE-2017-2659 High 2019-03-21 Not applicable No public exploit It was found that dropbear before version 2013.59 with GSSAPI leaks whether given username is valid or invalid. When an invalid username is given, the GSSAPI authentication failure was incorrectly counted towards the maximum allowed number of password attempts.
CVE-2018-15599 Medium 2018-08-21 Not applicable No public exploit The recv_msg_userauth_request function in svr-auth.c in Dropbear through 2018.76 is prone to a user enumeration vulnerability because username validity affects how fields in SSH_MSG_USERAUTH messages are handled, a similar issue to CVE-2018-15473 in an unrelated codebase.
CVE-2017-9079 Medium 2017-05-19 Not applicable No public exploit Dropbear before 2017.75 might allow local users to read certain files as root, if the file has the authorized_keys file format with a command= option. This occurs because ~/.ssh/authorized_keys is read with root privileges and symlinks are followed.
CVE-2017-9078 High 2017-05-19 Not applicable No public exploit The server in Dropbear before 2017.75 might allow post-authentication root remote code execution because of a double free in cleanup of TCP listeners when the -a option is enabled.
CVE-2016-7409 Medium 2017-03-03 Not applicable No public exploit The dbclient and server in Dropbear SSH before 2016.74, when compiled with DEBUG_TRACE, allows local users to read process memory via the -v argument, related to a failed remote ident.
CVE-2016-7408 High 2017-03-03 Not applicable No public exploit The dbclient in Dropbear SSH before 2016.74 allows remote attackers to execute arbitrary code via a crafted (1) -m or (2) -c argument.
CVE-2016-7407 Critical 2017-03-03 Not applicable No public exploit The dropbearconvert command in Dropbear SSH before 2016.74 allows attackers to execute arbitrary code via a crafted OpenSSH key file.
CVE-2016-7406 Critical 2017-03-03 Not applicable No public exploit Format string vulnerability in Dropbear SSH before 2016.74 allows remote attackers to execute arbitrary code via format string specifiers in the (1) username or (2) host argument.
CVE-2016-3116 Medium 2016-03-22 Not applicable Working exploit published CRLF injection vulnerability in Dropbear SSH before 2016.72 allows remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data.
CVE-2013-4434 Medium 2013-10-25 Not applicable No public exploit Dropbear SSH Server before 2013.59 generates error messages for a failed logon attempt with different time delays depending on whether the user account exists, which allows remote attackers to discover valid usernames.
CVE-2013-4421 Medium 2013-10-25 Not applicable No public exploit The buf_decompress function in packet.c in Dropbear SSH Server before 2013.59 allows remote attackers to cause a denial of service (memory consumption) via a compressed packet that has a large size when it is decompressed.
CVE-2012-0920 High 2012-06-05 Not applicable No public exploit Use-after-free vulnerability in Dropbear SSH Server 0.52 through 2012.54, when command restriction and public key authentication are enabled, allows remote authenticated users to execute arbitrary code and bypass command restrictions via multiple crafted command requests, related to "channels concurrency."
CVE-2007-1099 High 2007-02-26 Not applicable No public exploit dbclient in Dropbear SSH client before 0.49 does not sufficiently warn the user when it detects a hostkey mismatch, which might allow remote attackers to conduct man-in-the-middle attacks.
CVE-2006-1206 Medium 2006-03-14 Not applicable Working exploit published Matt Johnston Dropbear SSH server 0.47 and earlier, as used in embedded Linux devices and on general-purpose operating systems, allows remote attackers to cause a denial of service (connection slot exhaustion) via a large number of connection attempts that exceeds the MAX_UNAUTH_CLIENTS defined value of 30.
CVE-2005-4178 Medium 2005-12-12 Not applicable No public exploit Buffer overflow in Dropbear server before 0.47 allows authenticated users to execute arbitrary code via unspecified inputs that cause insufficient memory to be allocated due to an incorrect expression that does not enforce the proper order of operations.
CVE-2004-2486 High 2004-12-31 Not applicable No public exploit The DSS verification code in Dropbear SSH Server before 0.43 frees uninitialized variables, which might allow remote attackers to gain access.
