Security readout for executives and security teams
CVE-2013-3927 affects Siemens COMOS client libraries in older 9.2 and 10.0 releases. A local user who should only have database read access may gain unintended write access. This is mainly an integrity risk for organizations still running legacy COMOS environments. Exposure is limited to environments running the affected Siemens COMOS versions where local users have COMOS client access and database read permissions. Organizations without COMOS, or running versions at or beyond the named fixed releases, are not indicated as exposed by the provided sources. Prioritize remediation if COMOS supports engineering, plant, or operational data where unauthorized database changes could affect safety, compliance, or service delivery. If COMOS is not deployed, document non-exposure. If deployed only in legacy environments, schedule upgrade planning with operational owners. Mitigation focus: Inventory Siemens COMOS 9.2 and 10.0 installations.; Upgrade affected 9.2 systems to 9.2.0.6.10 or later.; Upgrade affected 10.0 systems to 10.0.3.0.4 or later..
