The wiki component in Moodle through 2.6.11, 2.7.x before 2.7.10, 2.8.x before 2.8.8, and 2.9.x before 2.9.2 does not consider the mod/wiki:managefiles capability before authorizing file management, which allows remote authenticated users to delete arbitrary files by using a manage-files button in a text editor.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The wiki component in Moodle through 2.6.11, 2.7.x before 2.7.10, 2.8.x before 2.8.8, and 2.9.x before
    2.9.2 does not consider the mod/wiki:managefiles capability before authorizing file management, which
    allows remote authenticated users to delete arbitrary files by using a manage-files button in a text
    editor. (CVE-2015-5265)

Security update.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Moodle, an open-source course management system, installed on the remote host is version 2.7.x prior to 2.7.10, 2.8.x prior to 2.8.8, or 2.9.x prior to 2.9.2, and is affected by multiple vulnerabilities :

  - A flaw due to the program failing to restrict users properly allowing an authenticated remote attacker to delete arbitrary files uploaded from other users. (CVE-2015-5265) 
 - A race condition in the 'enrol/meta/locallib.php' script that can allow suspended students to get assigned a manager role in meta course for several minutes allowing an authenticated remote attacker to gain elevated privileges. (CVE-2015-5266) 
 - A flaw in the 'complex_random_string()' function in the 'lib/moodlelib.php' script that is due to the limitation of PHP randomization. This can cause the program to create predictable password recovery tokens. (CVE-2015-5267) 
 - A flaw in the lesson module that is due to the program failing to protect against making new attempts to answer some questions allowing an authenticated remote attacker to re-attempt answering questions in the lesson. (CVE-2015-5264) 
 - A flaw in the rating component that is due to the program failing to check separate groups allowing an authenticated remote attacker to view ratings from other groups. (CVE-2015-5268) 
 - A flaw that allows a stored cross-site scripting (XSS) attack. This flaw exists because the 'group/overview.php' script does not validate input to grouping descriptions before returning it to users. This may allow an authenticated, remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server. (CVE-2015-5269) 
 - A flaw due to the program failing to check group access when posting to 'all participants' in forum allowing a remote attacker to bypass access restrictions and post to arbitrary locations. (CVE-2015-5272)
