CVE-2011-4302: n/a vulnerability

CVE-2011-4302: mnet/xmlrpc/client.php in MNET in Moodle 1.9.x before 1.9.14, 2.0.x before 2.0.5, and 2.1.x before 2.1.2 do...

mnet/xmlrpc/client.php in MNET in Moodle 1.9.x before 1.9.14, 2.0.x before 2.0.5, and 2.1.x before 2.1.2 does not properly process the return value of the openssl_verify function, which allows remote attackers to bypass validation via a crafted certificate.

Security readout for executives and security teams

Older Moodle deployments using MNET could accept a crafted certificate because certificate verification was handled incorrectly. This could let a remote attacker bypass a trust check. The provided sources name fixed Moodle releases, but do not show active exploitation or quantify business impact. Exposure is most likely in legacy Moodle 1.9, 2.0, or 2.1 systems where MNET XML-RPC functionality remains enabled or reachable. These branches are very old, so remaining exposure may indicate broader unsupported-platform risk. Treat this as a legacy-platform remediation item, not an emergency based on supplied evidence. Prioritize upgrades if Moodle is internet-facing, supports cross-site trust, or remains business-critical. Mitigation focus: Upgrade Moodle to 1.9.14, 2.0.5, 2.1.2, or a supported later release.; Check Moodle guidance for branch-specific remediation and migration advice.; Retire unsupported Moodle branches where feasible..
