Akamai Guardicore Platform Agent (GPA) and Zero Trust Client on Linux and macOS allow TOCTOU-based local privilege escalation. The GPA service creates an IPC socket in the world-writable /tmp directory. It accepts unauthenticated IPC control messages. This enables a TOCTOU vulnerability in the HandleSaveLogs() function of the GPA service, by creating a log file and manipulating it into a symlink that points to the targeted path; this can allow an unprivileged local user to make arbitrary root-owned files world-writable. In addition, a diagnostic collection tool (gimmelogs) running with root privileges was vulnerable to command injection from the dbstore, offering a second privilege escalation vector. (On Windows, gimmelogs does not have command injection but does allow writing a ZIP archive to an unintended location.) This affects Akamai Guardicore Platform Agent 7.0 through 7.3.1 and Akamai Zero Trust Client 6.0 through 6.1.5.
AnalysisAI
Local privilege escalation in Akamai Guardicore Platform Agent 7.0-7.3.1 and Zero Trust Client 6.0-6.1.5 on Linux and macOS enables unprivileged users to gain root access through two distinct vectors: a TOCTOU race condition in the HandleSaveLogs() function that creates world-writable root-owned files via symlink manipulation in /tmp, and command injection in the gimmelogs diagnostic tool executing with root privileges. The vulnerability requires local access with high attack complexity (CVSS AC:H) but no authentication (PR:N), affecting endpoint security agents that typically run with elevated privileges. …
