WebSVN before 2.6.1 allows remote attackers to execute arbitrary commands via shell metacharacters in the search parameter.

A flaw was found in WebSVN 2.3.2. Without prior authentication, if the 'allowDownload' option is enabled in config.php, an attacker can invoke the dl.php script and pass a well formed 'path' argument to execute arbitrary commands against the underlying operating system.

Cross-site scripting (XSS) vulnerability in WebSVN 2.3.3 and earlier allows remote attackers to inject arbitrary web script or HTML via the path parameter to log.php.

A vulnerability was found in websvn. Having a directory or file in a repository with its filename containing a XSS payload will cause it to be executed in various parts of the application.
