This critical-severity CVE scores 9.2 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 75% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

An insecure Apache configuration in ConfigServer Security & Firewall maps /usr/bin as CGI programs through the Messenger v3 HTTPS virtual host. A remote unauthenticated attacker whose address is blocked can request a mapped executable and run arbitrary commands as the Apache user. The vulnerability affects installations where CSF Messenger v3 and its HTTPS mode are enabled. WebPros addressed the vulnerability in version 16.31.
