CVE-2015-4537: Lockbox in EMC Documentum D2 before 4.5 uses a hardcoded passphrase when a server lacks a D2.Lockbox file,...

Security readout for executives and security teams

EMC Documentum D2 before 4.5 could fall back to a built-in passphrase when the server lacks a D2.Lockbox file. An authenticated remote user could use that passphrase to decrypt administrator tickets, creating a risk of privileged access to protected content workflows. Exposure is most likely in legacy EMC Documentum D2 deployments before 4.5, especially servers missing D2.Lockbox. The bundle does not identify CPEs, exact subversions, or internet exposure patterns. Prioritize remediation for any production D2 system because the issue can expose administrator tickets. Urgency is lower where D2 is absent, already upgraded, or access is tightly restricted. Mitigation focus: Upgrade EMC Documentum D2 to 4.5 or later per EMC guidance.; Verify each D2 server has a valid D2.Lockbox file.; Review vendor advisory ESA-2015-132 before making production changes..
