CVE-2010-20109

Estado: AplazadaAlta (8.7)—

Barracuda products, confirmed in Spam & Virus Firewall, SSL VPN, and Web Application Firewall versions prior to October 2010, contain a path traversal vulnerability in the view_help.cgi endpoint. The locale parameter fails to properly sanitize user input, allowing attackers to inject traversal sequences and null-byte terminators to access arbitrary files on the underlying system. By exploiting this flaw, unauthenticated remote attackers can retrieve sensitive configuration files such as /mail/snapshot/config.snapshot, potentially exposing credentials, internal settings, and other critical data.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector AV:N/PR:N/UI:N indica acceso remoto sin autenticación. Path traversal (CWE-22) en endpoint web expuesto permite lectura de archivos del sistema (T1005).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

El parámetro locale no depura correctamente la entrada del usuario, lo que permite a los atacantes inyectar secuencias de cruce y terminadores de byte nulo para acceder a archivos arbitrarios en el sistema subyacente. Al explotar esta vulnerabilidad, atacantes remotos no autenticados pueden recuperar archivos de configuración confidenciales como /mail/snapshot/config.snapshot, lo que podría exponer credenciales, configuración interna y otros datos críticos."
