CVE-2008-0455

Vulnerabilidad de secuencias de comandos en sitios cruzados (XSS) en el módulo mod_negotiation de Apache HTTP Server 2.2.6 y anteriores en las series 2.2.x, 2.0.61 y anteriores en las series 2.0.x, y 1.3.39 y anteriores en las series 1.3.x permite a usuarios remotos autenticados inyectar secuencias de comandos web o HTML de su elección subiendo un fichero con un nombre que contiene secuencias XSS y una extensión de fichero, lo cual conduce conduce a la inyección en respuestas HTTP (1) "406 Not Acceptable" o (2) "300 Multiple Choices" cuando se omite la extensión en la petición del fichero.

The httpd packages contain the Apache HTTP Server, which is the namesake project of The Apache Software Foundation. An input sanitization flaw was found in the mod_negotiation Apache HTTP Server module. A remote attacker able to upload or create files with arbitrary names in a directory that has the MultiViews options enabled, could use this flaw to conduct cross-site scripting attacks against users visiting the site. It was discovered that mod_proxy_ajp, when used in configurations with mod_proxy in load balancer mode, would mark a back-end server as failed when request processing timed out, even when a previous AJP CPing request was responded to by the back-end. A remote attacker able to make a back-end use an excessive amount of time to process a request could cause mod_proxy to not send requests to back-end AJP servers for the retry timeout period or until all back-end servers were marked as failed.
