CVE-2013-1862

mod_rewrite.c en el modulo mod_rewrite en Apache HTTP Server v2.2.x anterior a v2.2.25 escribe datos en un archivo de log sin eliminar caracteres no imprimibles, lo que podría permitir a un atacante remotos ejecutar comandos arbitrarios a través de una petición HTTP que contiene una secuencia de escape para un emulador de terminal.

The Apache HTTP Server is a popular web server. Cross-site scripting flaws were found in the mod_proxy_balancer module's manager web interface. If a remote attacker could trick a user, who was logged into the manager web interface, into visiting a specially-crafted URL, it would lead to arbitrary web script execution in the context of the user's manager interface session. It was found that mod_rewrite did not filter terminal escape sequences from its log file. If mod_rewrite was configured with the RewriteLog directive, a remote attacker could use specially-crafted HTTP requests to inject terminal escape sequences into the mod_rewrite log file. If a victim viewed the log file with a terminal emulator, it could result in arbitrary command execution with the privileges of that user.
