CVE-2008-5177

Estado: ModificadaAlta (10)—💥 Exploit

Stack-based buffer overflow in the DtbClsLogin function in Yosemite Backup 8.7 allows remote attackers to (1) execute arbitrary code on a Linux platform, related to libytlindtb.so; or (2) cause a denial of service (application crash) and possibly execute arbitrary code on a Windows platform, related to ytwindtb.dll; via a long username field during authentication.

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.
