Description

The version of ViewVC hosted on the remote host is vulnerable to a HTML injection attack. Requesting a URL with an invalid parameter name in the query string generates an error message that echoes back the parameter name. Any URLs included in the invalid parameter name become hyperlinks. A remote attacker could trick a user into requesting a malicious URL to facilitate a social engineering attempt.

According to some reports, there is also an unrelated cross-site scripting issue in this version of ViewVC, though Nessus has not checked for that.
