Product Description:
Apache Archiva is an extensible repository management software that
helps taking care of your own personal or enterprise-wide build artifact
repository. It is the perfect companion for build tools such as Maven,
Continuum, and ANT.

proxying, security access management, build artifact storage, delivery,
browsing, indexing and usage reporting, extensible scanning
functionality... and many more! 
(Source: http://archiva.apache.org/)
--------------------------------------------------------------------

Vulnerability Details:
These issues allow an attacker to access and use the application with
the session of a logged on user. In this case if an administrative
account is exploited, total application compromise may be acheived.
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.
