Summary
Vitec Flamingo 4.12.2 contains an unauthenticated OS command injection vulnerability in the admin/ajax/gen_graphs.php endpoint. Attackers can execute arbitrary commands by supplying shell metacharacters in the start, end, key, or format HTTP GET parameters. Lack of input sanitization leads to direct command execution via passthru() with root privileges.
Risk Assessment
The organization is at risk of complete server compromise by an unauthenticated attacker, potentially leading to data theft, malware installation, or service disruption.
Recommendation
Immediately update Vitec Flamingo to the latest patched version. As a temporary measure, restrict access to the admin/ajax/gen_graphs.php endpoint to trusted IP addresses and implement input sanitization.
Original NVD description (English source)
Vitec Flamingo 4.12.2 contains an unauthenticated OS command injection vulnerability in the admin/ajax/gen_graphs.php endpoint that allows remote unauthenticated attackers to execute arbitrary commands by supplying shell metacharacters in the start, end, key, or format HTTP GET parameters. Attackers can exploit the lack of input sanitization in the graph generation script, which passes user-supplied values directly to shell commands via passthru(), to execute arbitrary OS commands with root privileges due to the web server context having passwordless sudo access.
