ViewVC before versions 1.1.28 and 1.2.1 has a XSS vulnerability in CVS
show_subdir_lastmod support. The impact of this vulnerability is mitigated
by the need for an attacker to have commit privileges to a CVS repository
exposed by an otherwise trusted ViewVC instance that also has the
show_subdir_lastmod
feature enabled. The attack vector involves files
with unsafe names (names that, when embedded into an HTML stream, would
cause the browser to run unwanted code), which themselves can be
challenging to create. This vulnerability is patched in versions 1.2.1 and
1.1.28.
