Apache Software Foundation Apache Guacamole vulnerabilities

CVE-2024-35164 [MEDIUM] CWE-129 CVE-2024-35164: The terminal emulator of Apache Guacamole 1.5.5 and older does not properly validate console codes r 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

CVE-2023-43826 [HIGH] CWE-190 CVE-2023-43826: Apache Guacamole 1.5.3 and older do not consistently ensure that values received from a VNC server w 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.

CVE-2023-30575 [MEDIUM] CWE-131 CVE-2023-30575: Apache Guacamole 1.5.1 and older may incorrectly calculate the lengths of instruction elements sent 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-2023-30576 [MEDIUM] CWE-416 CVE-2023-30576: Apache Guacamole 0.9.10 through 1.5.1 may continue to reference a freed RDP audio input buffer. Depe 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-2021-43999 [HIGH] CWE-287 CVE-2021-43999: Apache Guacamole 1.2.0 and 1.3.0 do not properly validate responses received from a SAML identity pr 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] CWE-200 CVE-2021-41767: Apache Guacamole 1.3.0 and older may incorrectly include a private tunnel identifier in the non-priv 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-2018-1340 [HIGH] CWE-311 CVE-2018-1340: Prior to 1.0.0, Apache Guacamole used a cookie for client-side storage of the user's session token. 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] CWE-362 CVE-2017-3158: A race condition in Guacamole's terminal emulator in versions 0.9.5 through 0.9.10-incubating could 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.
