CVE-2025-55275Network attack vector

Administrator impersonation via concurrent session handling

Published Mar 26, 2026 · Updated Mar 26, 2026

Session concurrency handling in HCL Aftermarket DPC 1.0.0 allows remote authenticated users to hijack or impersonate an administrator. HCL has not published the affected session-management locus or the operation that incorrectly permits concurrent sessions to assume an administrator's identity. The CNA assessment requires low-privileged access, user interaction, and high-complexity conditions; reported effects are limited data exposure and service interruption.
