inc/functions_time.php in MyBB (aka MyBulletinBoard) 1.4.10, and possibly earlier versions, allows remote attackers to cause a denial of service (CPU consumption) via a crafted request with a large year value, which triggers a long loop, as reachable through member.php and possibly other vectors.

Security readout for executives and security teams

This is an old MyBB denial-of-service issue. A remote request could make the forum spend excessive CPU time processing an unrealistic year value, potentially slowing or disrupting the site. It affects MyBB 1.4.10 and possibly earlier versions according to the CVE description. Exposure is most likely limited to internet-facing legacy MyBB forums running 1.4.10 or possibly earlier 1.4 releases. Modern or upgraded MyBB installations are not shown as affected by the provided sources. Treat this as a moderate legacy exposure issue. It is not shown as actively exploited, but an exposed vulnerable forum could be disrupted remotely and should be upgraded or retired. Mitigation focus: Inventory any MyBB installations and confirm exact versions.; Apply the MyBB 1.4.11 security update or later supported vendor release.; Restrict or retire obsolete internet-facing MyBB deployments..
