CVE-2012-2104

Estado: ModificadaMedia (6.8)—💥 Exploit

cgi-bin/munin-cgi-graph in Munin 2.x writes data to a log file without sanitizing non-printable characters, which might allow user-assisted remote attackers to inject terminal emulator escape sequences and execute arbitrary commands or delete arbitrary files via a crafted HTTP request.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
