Description Huzaifa S. Sidhpurwala 2011-04-13 08:41:13 UTC

Python's SimpleHTTPServer class is a simple HTTP server, documented as
serving up the content of the pwd and below readonly via GET and HEAD
commands:

$ python -m SimpleHTTPServer
Serving HTTP on 0.0.0.0 port 8000 ...

However, by inserting "../" path fragments within the path section of
the URL, it's possible to traverse other directories within the
filesystem.

For example:

lynx localhost:8000/../../../../..

shows 5 directories above in the directory structure.

We can also browse /proc and /sys on this example using:

lynx localhost:8000/../../../../../../../../proc
lynx localhost:8000/../../../../../../../../sys

(by browsing to find the correct number of ".." entries to locate the
root directory).

Comment 2 Huzaifa S. Sidhpurwala 2011-07-01 06:06:02 UTC

http://bugs.python.org/issue11197#msg139056

suggests that this bug cannot be reproduced. 
Also SimpleHTTPServer is supposed to serve contents from the current directory and any directories below it.

Closing this issue.

Comment 6 Huzaifa S. Sidhpurwala 2011-07-01 08:31:59 UTC

This is NOT a security issue, in fact this is not a bug at all. lynx was used incorrectly. This resulted in files being viewed from the local system and not from the web.

I asked MITRE (via the http://cveform.mitre.org/) to REJECT the CVE.
