CVE Severity Published▾ Status Exploitation Description
CVE-2024-35164 High 2025-07-02 Not applicable No public exploit The terminal emulator of Apache Guacamole 1.5.5 and older does not properly validate console codes received from servers via text-based protocols like SSH. If a malicious user has access to a text-based connection, a specially-crafted sequence of console codes could allow arbitrary code to be executed with the privileges of the running guacd process. Users are recommended to upgrade to version 1.6.0, which fixes this issue.
CVE-2023-43826 High 2023-12-19 Not applicable No public exploit Apache Guacamole 1.5.3 and older do not consistently ensure that values received from a VNC server will not result in integer overflow. If a user connects to a malicious or compromised VNC server, specially-crafted data could result in memory corruption, possibly allowing arbitrary code to be executed with the privileges of the running guacd process. Users are recommended to upgrade to version 1.5.4, which fixes this issue.
CVE-2023-30576 High 2023-06-07 Not applicable No public exploit Apache Guacamole 0.9.10 through 1.5.1 may continue to reference a freed RDP audio input buffer. Depending on timing, this may allow an attacker to execute arbitrary code with the privileges of the guacd process.
CVE-2023-30575 High 2023-06-07 Not applicable No public exploit Apache Guacamole 1.5.1 and older may incorrectly calculate the lengths of instruction elements sent during the Guacamole protocol handshake, potentially allowing an attacker to inject Guacamole instructions during the handshake through specially-crafted data.
CVE-2021-43999 High 2022-01-11 Not applicable No public exploit Apache Guacamole 1.2.0 and 1.3.0 do not properly validate responses received from a SAML identity provider. If SAML support is enabled, this may allow a malicious user to assume the identity of another Guacamole user.
CVE-2021-41767 Medium 2022-01-11 Not applicable No public exploit Apache Guacamole 1.3.0 and older may incorrectly include a private tunnel identifier in the non-private details of some REST responses. This may allow an authenticated user who already has permission to access a particular connection to read from or interact with another user's active use of that same connection.
CVE-2020-11997 Medium 2021-01-19 Not applicable No public exploit Apache Guacamole 1.2.0 and earlier do not consistently restrict access to connection history based on user visibility. If multiple users share access to the same connection, those users may be able to see which other users have accessed that connection, as well as the IP addresses from which that connection was accessed, even if those users do not otherwise have permission to see other users.
CVE-2020-9498 Medium 2020-07-02 Not applicable No public exploit Apache Guacamole 1.1.0 and older may mishandle pointers involved inprocessing data received via RDP static virtual channels. If a userconnects to a malicious or compromised RDP server, a series ofspecially-crafted PDUs could result in memory corruption, possiblyallowing arbitrary code to be executed with the privileges of therunning guacd process.
CVE-2020-9497 Medium 2020-07-02 Not applicable No public exploit Apache Guacamole 1.1.0 and older do not properly validate datareceived from RDP servers via static virtual channels. If a userconnects to a malicious or compromised RDP server, specially-craftedPDUs could result in disclosure of information within the memory ofthe guacd process handling the connection.
CVE-2019-19603 High 2019-12-09 Not applicable No public exploit SQLite 3.30.1 mishandles certain SELECT statements with a nonexistent VIEW, leading to an application crash.
CVE-2018-1340 High 2019-02-07 No exploit published No public exploit Prior to 1.0.0, Apache Guacamole used a cookie for client-side storage of the user's session token. This cookie lacked the "secure" flag, which could allow an attacker eavesdropping on the network to intercept the user's session token if unencrypted HTTP requests are made to the same domain.
CVE-2017-3158 High 2018-01-18 No exploit published No public exploit A race condition in Guacamole's terminal emulator in versions 0.9.5 through 0.9.10-incubating could allow writes of blocks of printed data to overlap. Such overlapping writes could cause packet data to be misread as the packet length, resulting in the remaining data being written beyond the end of a statically-allocated buffer.
CVE-2016-1566 Medium 2017-02-02 Not applicable No public exploit Cross-site scripting (XSS) vulnerability in the file browser in Guacamole 0.9.8 and 0.9.9, when file transfer is enabled to a location shared by multiple users, allows remote authenticated users to inject arbitrary web script or HTML via a crafted filename. NOTE: this vulnerability was fixed in guacamole.war on 2016-01-13, but the version number was not changed.
