Open Ticket Request System (OTRS) 2.3.x before 2.3.6 and 2.4.x before 2.4.8 does not properly handle the matching of Perl regular expressions against HTML e-mail messages, which allows remote attackers to cause a denial of service (CPU consumption) via a large message, a different vulnerability than CVE-2010-2080.

Security readout for executives and security teams

This issue affects old OTRS ticketing systems that parse HTML email. A specially large email can make the system spend excessive CPU time, potentially slowing or stopping ticket processing. The business risk is service disruption, not data theft, based on the supplied sources. Exposure is likely limited to organizations still running OTRS 2.3.x or 2.4.x below the fixed versions and processing inbound HTML email into tickets. Prioritize remediation if any legacy OTRS instance still handles email-driven tickets. The main concern is operational downtime or delayed support workflows, especially for customer-facing service desks. Mitigation focus: Upgrade OTRS 2.3.x to 2.3.6 or later, where applicable.; Upgrade OTRS 2.4.x to 2.4.8 or later, where applicable.; Check the OTRS advisory for exact vendor remediation guidance..
