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://.
Impact: An attacker can execute arbitrary command via a successful exploit in the context of the vulnerable software.
Affected OS: Windows, Linux, FreeBSD, Solaris, Other Unix, Network Device, Mac OS, iOS, Android, Others
