Severity:	normal
Title:	WebSVN: Multiple vulnerabilities
Date:	03/09/2009
Bugs:	#243852
ID:	200903-20

Synopsis

Multiple vulnerabilities in WebSVN allow for file overwrite and information disclosure.

Background

WebSVN is a web-based browsing tool for Subversion repositories written in PHP.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-apps/websvn	< 2.1.0	>= 2.1.0	All supported architectures

Description

James Bercegay of GulfTech Security reported a Cross-site scripting (XSS) vulnerability in the getParameterisedSelfUrl() function in index.php (CVE-2008-5918) and a directory traversal vulnerability in rss.php when magic_quotes_gpc is disabled (CVE-2008-5919).
Bas van Schaik reported that listing.php does not properly enforce access restrictions when using an SVN authz file to authenticate users (CVE-2009-0240).

Impact

A remote attacker can exploit these vulnerabilities to overwrite arbitrary files, to read changelogs or diffs for restricted projects and to hijack a user's session.

Workaround

There is no known workaround at this time.

Resolution

All WebSVN users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-apps/websvn-2.1.0"
