CVE-2005-2540

Estado: ModificadaMedia (5)—💥 Exploit

CRLF injection vulnerability in FlatNuke 2.5.5 and possibly earlier versions allows remote attackers to execute arbitrary PHP commands via an ASCII char 13 (carriage return) in the signature field, which is injected into a PHP script without a preceding comment character, which can then be executed by a direct 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.
