CVE-2009-10005

Status: DeferredHigh (8.7)—

ContentKeeper Web Appliance (now maintained by Impero Software) versions prior to 125.10 expose the mimencode binary via a CGI endpoint, allowing unauthenticated attackers to retrieve arbitrary files from the filesystem. By crafting a POST request to /cgi-bin/ck/mimencode with traversal and output parameters, attackers can read sensitive files such as /etc/passwd outside the webroot.

CVSS

Exploitation probability (EPSS)

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).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vector AV:N/PR:N/UI:N indica acceso remoto sin privilegios ni interacción; CGI expuesto permite lectura directa de archivos sensibles (/etc/passwd) mediante path traversal sin autenticación.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
