Common Vulnerabilities and Exposures assigned an identifier CVE-2013-4522 to the following vulnerability:

Name: CVE-2013-4522
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4522
Assigned: 20130612
Reference: http://openwall.com/lists/oss-security/2013/11/25/1
Reference: http://git.moodle.org/gw?p=moodle.git&a=search&h=HEAD&st=commit&s=MDL-38743

lib/filelib.php in Moodle through 2.2.11, 2.3.x before 2.3.10, 2.4.x before 2.4.7, and 2.5.x before 2.5.3 does not send "Cache-Control: private" HTTP headers, which allows remote attackers to obtain sensitive information by requesting a file that had been previously retrieved by a caching proxy server.
