Description

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.
