CVE-2013-4522 describes an information disclosure vulnerability in Moodle versions 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. The vulnerability arises because the 'lib/filelib.php' component fails to send "Cache-Control: private" HTTP headers. This oversight allows remote attackers to obtain sensitive information by requesting files that have been previously cached by a proxy server. The vulnerability has a CVSS score of 5.0 (Medium), indicating a network-based attack with low complexity, requiring no authentication, and resulting in partial confidentiality impact. There is no integrity or availability impact. Currently, there is no evidence of active exploitation, nor is exploit code publicly available on platforms like Metasploit or ExploitDB. The vulnerability has received minimal community discussion and media coverage, suggesting a low level of public attention.
