WebSVN "path" Cross-Site Scripting Vulnerability

Description

Sony has discovered a vulnerability in WebSVN, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed via the "path" parameter to e.g. comp.php or revision.php is not properly sanitised in the "getLog()" function in svnlook.php before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerability is confirmed in version 2.3.0. Prior versions may also be affected.
