Summary

ViewVC is a browser interface for CVS and Subversion version control repositories. In versions 1.1.0 through 1.1.31 and 1.2.0 through 1.2.3, the standalone.py script provided in the ViewVC distribution can expose the contents of the host server's filesystem though a directory traversal-style attack. This is fixed in versions 1.1.31 and 1.2.4.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
