TITLE:
YaPiG Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA15600

VERIFY ADVISORY:
http://secunia.com/advisories/15600/

CRITICAL:
Highly critical

IMPACT:
Cross Site Scripting, Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
YaPiG 0.x
http://secunia.com/product/3795/

DESCRIPTION:
Some vulnerabilities have been reported in YaPiG, which can be
exploited to remove or create arbitrary directories, conduct
cross-site scripting attacks, and compromise a vulnerable system.

1) It is possible to upload arbitrary files to a directory inside the
web root. This can e.g. be exploited to execute arbitrary PHP code by
uploading a malicious PHP file.

Successful exploitation requires administrative privileges.

2) Input passed to the "phid" parameter in "view.php" isn't properly
sanitised before being returned to users. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of a vulnerable site.

3) Input passed to the "BASE_DIR" and "YAPIG_PATH" parameters isn't
properly verified, before it is used to include files. This can be
exploited to include arbitrary files from external and local
resources.

Successful exploitation requires that "register_globals" is enabled.

4) Input passed to the "dir" parameter in "upload.php" isn't properly
verified before being used. This can be exploited to create or remove
arbitrary directories via directory traversal attacks.

Successful exploitation requires administrative privileges.

The vulnerabilities have been reported in versions 0.92b, 0.93u, and
0.94u. Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
