Description

This security bulletin contains information about 1 vulnerability.

1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2011-1584)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a remote #AU# to read and manipulate data.

The updateFile function in inc/core/class.dc.media.php in the Media Manager in Dotclear before 2.2.3 does not properly restrict pathnames, which allows remote authenticated users to upload and execute arbitrary PHP code via the media_path or media_file parameter. NOTE: some of these details are obtained from third party information.

Remediation

Install update from vendor's website.
