FKIE_CVE-2010-20109
Vulnerability from fkie_nvd - Published: 2025-08-21 20:15 - Updated: 2026-06-16 23:19
Severity
Summary
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.

"value": "Los productos Barracuda, confirmados en versiones de Firewall Antispam y Virus, SSL VPN y Firewall de Aplicaciones Web anteriores a octubre de 2010, contienen una vulnerabilidad de path traversal en el endpoint view_help.cgi. El par\u00e1metro 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 configuraci\u00f3n confidenciales como /mail/snapshot/config.snapshot, lo que podr\u00eda exponer credenciales, configuraci\u00f3n interna y otros datos cr\u00edticos."
