CVE-2008-2938

Estado: ModificadaMedia (4.3)—💥 Exploit
Directory traversal vulnerability in Apache Tomcat 4.1.0 through 4.1.37, 5.5.0 through 5.5.26, and 6.0.0 through 6.0.16, when allowLinking and UTF-8 are enabled, allows remote attackers to read arbitrary files via encoded directory traversal sequences in the URI, a different vulnerability than CVE-2008-2370. NOTE: versions earlier than 6.0.18 were reported affected, but the vendor advisory lists 6.0.16 as the last affected version.
CVSS

Versión: 2.0
Vector: AV:N/AC:M/Au:N/C:P/I:N/A:N
Puntuación base: 4.3
Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 100%
Percentil entre todas las CVEs puntuadas: 100
Fecha de la puntuación: 29/9/2026
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.
