Status: ModifiedCritical (9.8)—Exploit
Severity9.8Critical · CVSS 3.1
Exploitation probability98 %higher than 100% of CVEs

Public exploitAvailablePublished on Exploit-DB · Proof of concept on GitHub (unverified) · Metasploit module (reliable, widely available exploit) · Nuclei template (automated mass detection)

An issue was discovered in rConfig 3.9.2. An attacker can directly execute system commands by sending a GET request to ajaxServerSettingsChk.php because the rootUname parameter is passed to the exec function without filtering, which can lead to command execution.

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
