CVE-2025-34305
Full vulnerability record from the local CVENow database.
Description
IPFire versions prior to 2.29 (Core Update 198) contain multiple stored cross-site scripting (XSS) vulnerabilities caused by a bug in the cleanhtml() function (/var/ipfire/header.pl) that fails to apply HTML-entity encoding to user input. When an authenticated user submits data to affected endpoints - for example, POST /cgi-bin/wakeonlan.cgi (CLIENT_COMMENT), /cgi-bin/dhcp.cgi (ADVOPT_DATA, FIX_REMARK, FIX_FILENAME, FIX_ROOTPATH), /cgi-bin/connscheduler.cgi (ACTION_COMMENT), /cgi-bin/dnsforward.cgi (REMARK), /cgi-bin/vpnmain.cgi (REMARK), or /cgi-bin/dns.cgi (REMARK) - the application calls escape() and HTML::Entities::encode_entities() but never assigns the sanitized result back to the output variable. The original unsanitized value is therefore stored and later rendered in the web interface without proper sanitation or encoding, allowing injected scripts to execute in the context of other users who view the affected entries.

"value": "Las versiones de IPFire anteriores a la 2.29 (Core Update 198) contienen múltiples vulnerabilidades de cross-site scripting (XSS) almacenado causadas por un error en la función cleanhtml() (/var/ipfire/header.pl) que no aplica la codificación de entidades HTML a la entrada del usuario. Cuando un usuario autenticado envía datos a los puntos finales afectados -por ejemplo, POST /cgi-bin/wakeonlan.cgi (CLIENT_COMMENT), /cgi-bin/dhcp.cgi (ADVOPT_DATA, FIX_REMARK, FIX_FILENAME, FIX_ROOTPATH), /cgi-bin/connscheduler.cgi (ACTION_COMMENT), /cgi-bin/dnsforward.cgi (REMARK), /cgi-bin/vpnmain.cgi (REMARK), o /cgi-bin/dns.cgi (REMARK)- la aplicación llama a escape() y HTML::Entities::encode_entities() pero nunca asigna el resultado saneado de vuelta a la variable de salida. El valor original sin sanear se almacena, por lo tanto, y se renderiza posteriormente en la interfaz web sin la sanación o codificación adecuadas, permitiendo que los scripts inyectados se ejecuten en el contexto de otros usuarios que visualizan las entradas afectadas."
