Description

A maliciously constructed svn+ssh:// URL would cause Subversion clients before 1.8.19, 1.9.x before 1.9.7, and 1.10.0.x through 1.10.0-alpha3 to run an arbitrary shell command. Such a URL could be generated by a malicious server, by a malicious user committing to a honest server (to attack another user of that server's repositories), or by a proxy server. The vulnerability affects all clients, including those that use file://, http://, and plain (untunneled) svn://.

Affected products

Apache Software Foundation Apache Subversion: through 1.8.18; 1.9.0, 1.9.1, 1.9.2, 1.9.3, 1.9.4, 1.9.5 (+5)
