CVE-2002-2295

Estado: ModificadaAlta (7.5)—💥 Exploit

Buffer overflow in Pico Server (pServ) 2.0 beta 1 through beta 5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) a 1024-byte TCP stream message, which triggers an off-by-one buffer overflow, or (2) a long method name in an HTTP request, (3) a long version number in an HTTP request, (4) a long User-Agent header, or (5) a long file path.

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.
