Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU42310

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2013-4522

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

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.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Moodle: 1.1.1 - 2.5.2

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2013-4523

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

Vulnerability allows a remote attacker to perform Cross-site scripting attacks.

An input validation error exists in message/lib.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.
