Subject: CVE-2024-35164: Apache Guacamole: Improper input validation of
console codes
Severity: moderate
Base CVSS Score: 6.8 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N)
Affected versions:
- Apache Guacamole 0.8.0 through 1.5.5
Description:
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.
