Please note that binary patches are not produced for individual vulnerabilities. To obtain the binary fix for a particular vulnerability you should upgrade to an Apache Archiva version where that vulnerability has been fixed.
For more information about reporting vulnerabilities, see the Apache Security Team page.
Apache Archiva is affected by a vulnerability in the version of the Struts library being used, which allows a malicious user to run code on the server remotely. More details about the vulnerability can be found at http://struts.apache.org/2.2.1/docs/s2-005.html.
All users are recommended to upgrade to Archiva 1.3.6, which configures Struts in such a way that it is not affected by this issue.
Archiva 1.4-M3 and later is not affected by this issue.
An attacker can build a simple html page containing a hidden Image tag (eg: <img src=vulnurl width=0 height=0 />) and entice the administrator to access the page.
Apache Archiva doesn't check which form sends credentials. An attacker can create a specially crafted page and force archiva administrators to view it and change their credentials. To fix this, a referrer check was added to the security interceptor for all secured actions. A prompt for the administrator's password when changing a user account was also set in place. This fix is available in version 1.3.2 of Apache Archiva. All users must upgrade to this version (or higher).
