ViewVC before 1.1.11 allows remote attackers to bypass the cvsdb rowlimit configuration setting, and consequently conduct resource-consumption attacks, via the limit parameter, as demonstrated by a "query revision history" request.

Unspecified vulnerability in ViewVC 1.0 before 1.0.9 and 1.1 before 1.1.2 has unknown impact and remote attack vectors related to "printing illegal parameter names and values."

Cross-site scripting (XSS) vulnerability in viewvc.py in ViewVC 1.0 before 1.0.9 and 1.1 before 1.1.2 allows remote attackers to inject arbitrary web script or HTML via the view parameter. NOTE: some of these details are obtained from third party information.

ViewVC before 1.0.5 stores sensitive information under the web root with insufficient access control, which allows remote attackers to read files and list folders under the hidden CVSROOT folder.

ViewVC before 1.0.5 includes "all-forbidden" files within search results that list CVS or Subversion (SVN) commits, which allows remote attackers to obtain sensitive information.

ViewVC before 1.0.5 provides revision metadata without properly checking whether access was intended, which allows remote attackers to obtain sensitive information by reading (1) forbidden pathnames in the revision view, (2) log history that can only be reached by traversing a forbidden object, or (3) forbidden diff view path parameters.
