Cross-site scripting (XSS) vulnerability in the "extra" details in the DiffSource.getrow function in lib/viewvc.py in ViewVC 1.0.x before 1.0.13 and 1.1.x before 1.1.16 allows remote authenticated users with repository commit access to inject arbitrary web script or HTML via the "function name" line.
