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

-------------------------------------------------------------------

1 www-apps/websvn < 2.1.0 >= 2.1.0

 

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"
