Description Agostino Sarubbo 2013-05-26 18:49:53 UTC

From oss-security mailing list:

As mentioned in early messages to oss-sec, I've inherited
maintainership of the cgit codebase and am gradually auditing it.
Today I found a nasty directory traversal:

http://somehost/?url=/somerepo/about/../../../../etc/passwd

This should be pretty straightforward to categorize.

Exploitation looks like:

I've committed a fix for it here:
http://git.zx2c4.com/cgit/commit/?h=wip&id=babf94e04e74123eb658a823213c062663cdadd6

And this fix will be in the master branch and a new release will be made soon.

Cgit by default is not vulnerable to this, and the vulnerability only
exists when a user has configured cgit to use a readme file from a
filesystem filepath instead of from the git repo itself. Until a
release is made, administrators are urged to disable reading the
readme file from a filepath, if currently enabled.
