Descriptions

The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion 1.5.x and 1.6.x before 1.6.17, when the SVNPathAuthz short_circuit option is disabled, does not properly enforce permissions for files that had been publicly readable in the past, which allows remote attackers to obtain sensitive information via a replay REPORT operation.

El módulo mod_dav_svn para Apache HTTP Server, como se distribuye en Apache Subversion v1.5.x y v1.6.x anteriores a 1.6.17,cuando la opción SVNPathAuthz short_circuit está deshabilitada no se aplican correctamente los permisos para los archivos que habían sido legibles públicamente en el pasado, lo que permite a atacantes remotos obtener información sensible a través de una operación de reproducción de INFORMES.
