CVE-2023-4677
CWE-287Published: November 23, 2023· Updated: Jun 17, 2026
Official Description
Cron log backup files contain administrator session IDs. It is trivial for any attacker who can reach the Pandora FMS Console to scrape the cron logs directory for cron log backups. The contents of these log files can then be abused to authenticate to the application as an administrator. This issue affects Pandora FMS <= 772.
Risk Analysis
Pandora FMS exposes administrator session IDs in cron log backup files. An attacker with network access can scrape these logs to hijack administrative sessions, leading to full application compromise.
No public exploit is known, and it is not in the CISA KEV. It is remotely exploitable with low attack complexity.
Upgrade Pandora FMS to a version beyond 772 and ensure log directories are properly secured with restricted permissions.
Technical Analysis
CVE-2023-4677 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-287): Authentication bypass vulnerabilities allow attackers to access protected resources without valid credentials.
