[waraxe-2012-SA#081] – Multiple Vulnerabilities in Coppermine 1.5.18

The Coppermine web picture gallery script version 1.5.18 is affected by multiple vulnerabilities. The first vulnerability is a stored cross-site scripting (XSS) in the picture keywords feature. This vulnerability allows an attacker with appropriate privileges to insert malicious code in the keywords field, which is later displayed in the HTML meta section, leading to XSS attacks. The second vulnerability is a path disclosure vulnerability in the "visible" feature of the software. This vulnerability allows an attacker to disclose sensitive information about the file structure of the server.

Mitigation:

To mitigate the stored XSS vulnerability, it is recommended to properly sanitize user-supplied input data before outputting it as HTML. To mitigate the path disclosure vulnerability, it is recommended to validate user input to prevent the disclosure of sensitive information.

Affected versions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Tests were conducted against Coppermine version 1.5.18.

###############################################################################
1. Stored XSS in picture keywords
###############################################################################

Reason: failure to sufficiently sanitize user-supplied input data
Preconditions: privileges needed for picture keywords editing

Coppermine user with appropriate privileges is able to modify picture information:

http://localhost/cpg1518/edit_one_pic.php?id=1&what=picture

There is a field in form named as "Keywords (separate with semicolon)".
After insertion to database those keywords are later used in html meta section.
It appears, that specific user supplied data is not properly validated before
outputting as html to the end user, resulting in Stored XSS vulnerability.

Testing:

1. Open picture information editing page:

http://localhost/cpg1518/edit_one_pic.php?id=1&what=picture

2. Insert XSS payload below as keywords and click "Apply changes":

"><body onload=javascript:alert(String.fromCharCode(88,83,83))>

After that issue request to view this image:

http://localhost/cpg1518/displayimage.php?pid=1

As result we can observe XSS payload execution.
