CVE-2025-55275
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedHCL Aftermarket DPC is affected by Admin Session Concurrency vulnerability using which an attacker can exploit concurrent sessions to hijack or impersonate an admin user.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceHCL Aftermarket DPC contains a session concurrency vulnerability in its admin authentication mechanism. The application fails to properly restrict or manage concurrent admin sessions, allowing an attacker to potentially establish a competing session or exploit race conditions to hijack or impersonate an existing admin user's session.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Hcltech Aftermarket Cloud installation and versionLocate the Hcltech Aftermarket Cloud application and retrieve its installed version number. This may be found in the application itself, installation directory, or system inventory software.Affected if The installed version is exactly 1.0.0 (Hcltech Aftermarket Cloud version 1.0.0).
-
Confirm admin authentication is enabledVerify that the admin authentication mechanism is active on the Aftermarket Cloud installation. Check whether admin users can authenticate to the system.Affected if Admin authentication is enabled and functional on the affected version.
-
Review session management configurationExamine configuration files or settings related to session management within the Aftermarket Cloud application. Look for settings that control session behavior, session IDs, and session lifecycle.Affected if Session management configuration exists and allows multiple concurrent admin sessions without proper restriction.
-
Check concurrent session limitsInspect the application or its configuration to determine whether limits are enforced on concurrent admin sessions per user account.Affected if No limit is enforced on how many concurrent admin sessions a single user can maintain.
-
Verify session invalidation behaviorTest or inspect whether previous admin sessions are invalidated when a new login occurs, or if older sessions remain active alongside new ones.Affected if Previous admin sessions remain active after a new login (no session fixation protection or session invalidation on new auth).
A user is affected if they are running Hcltech Aftermarket Cloud version 1.0.0 with admin authentication enabled, and the application permits multiple concurrent admin sessions without proper session invalidation or concurrency controls.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper session management controls including session fixation protection, enforce session expiration, limit concurrent admin sessions per user, and invalidate previous sessions upon new login or suspicious activity.
