CVE-2016-1240

Estado: ModificadaAlta (7.8)—💥 Exploit

The Tomcat init script in the tomcat7 package before 7.0.56-3+deb8u4 and tomcat8 package before 8.0.14-1+deb8u3 on Debian jessie and the tomcat6 and libtomcat6-java packages before 6.0.35-1ubuntu3.8 on Ubuntu 12.04 LTS, the tomcat7 and libtomcat7-java packages before 7.0.52-1ubuntu0.7 on Ubuntu 14.04 LTS, and tomcat8 and libtomcat8-java packages before 8.0.32-1ubuntu1.2 on Ubuntu 16.04 LTS allows local users with access to the tomcat account to gain root privileges via a symlink attack on the Catalina log file, as demonstrated by /var/log/tomcat7/catalina.out.

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.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
