Vitec Flamingo 4.12.2 Unauthenticated OS Command Injection via gen_graphs.php

Published Jul 13, 2026 CVSS 4.0 · 9.3 Critical EPSS 4.0% KEV · Not listed

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.

Analysis

Technical impact

Vitec Flamingo 4.12.2 contains an unauthenticated OS command injection flaw in the admin/ajax/gen_graphs.php endpoint. The script accepts the start, end, key, and format GET parameters and forwards them directly to a shell via passthru() without any input sanitization. Because the web server runs with passwordless sudo, injection of shell metacharacters into these parameters lets an attacker execute arbitrary operating‑system commands with root privileges, giving full system compromise.

Affected Systems

The vulnerability is specific to Vitec Flamingo version 4.12.2. No other versions or products are identified as impacted.

Risk and Exploitability

The CVSS score of 9.3 signals critical severity, and the EPSS score of 4% indicates a moderate likelihood that exploit code exists in the wild. The flaw is not listed in CISA KEV, yet the lack of authentication and remote reachability of the gen_graphs.php endpoint make exploitation highly feasible. An attacker only needs to send a crafted HTTP GET request; if successful, arbitrary commands can be run as root due to passwordless sudo privileges, enabling a complete takeover of the host system.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Disable the admin/ajax/gen_graphs.php endpoint or remove graph generation functionality from the configuration.
Reconfigure the web server or application to run under a non‑privileged user and eliminate any passwordless sudo privileges for the web process to prevent elevated command execution.
Restrict external network access to the Flamingo server, ensuring only trusted networks can reach the gen_graphs.php endpoint.
