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 · unedited
Session Fixation vulnerabilities allow an attacker to fix a users session identifier before login providing an opportunity for session takeover on a product.  Affected products: ABB ASPECT - Enterprise v3.08.02; NEXUS Series v3.08.02; MATRIX Series v3.08.02

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 confidence

Session Fixation vulnerability in ABB ASPECT Enterprise, NEXUS Series, and MATRIX Series v3.08.02 allows attackers to pre-establish or predict session identifiers before user authentication. Upon login, the application reuses the attacker-controlled session ID, enabling session takeover and impersonation of legitimate users.

MitigationImplement session ID regeneration (rotation) upon successful authentication and invalidate any session IDs established prior to login. Additionally, bind sessions to additional factors like IP address or implement secure session token generation using cryptographically random values.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify device model and firmware version
    Access the ABB device web interface or administrative console and navigate to System Information or About section to view the firmware version. Alternatively, use SNMP or the device's API to query the firmware version.
    Affected if The firmware version is < 3.08.03 for any of these models: Aspect Ent 2, Aspect Ent 256, Aspect Ent 96, Nexus 2128, Nexus 2128 A, Nexus 2128 F, Nexus 2128 G, or Nexus 264.
  2. Verify session ID regeneration on login
    Inspect the application or web server logs during a login sequence. Capture the session identifier before and after authentication. Check if a new session ID is generated upon successful login.
    Affected if The session identifier remains the same before and after authentication, indicating session IDs are not being regenerated.
  3. Check session invalidation behavior
    After a user logs out and logs back in, examine whether previous session identifiers are invalidated or rejected. Attempt to use an old session ID after logout to see if it is still accepted.
    Affected if Old session IDs remain valid after logout or are not invalidated upon new login, allowing session fixation.
  4. Review session management configuration
    Access the ABB device administrative interface and look for session management settings. Check configuration files or registry entries related to session handling for whether session ID regeneration is enabled.
    Affected if Session ID regeneration upon authentication is disabled or not configured in the system.

If the device firmware version is < 3.08.03 and session IDs are not regenerated upon login, the environment is vulnerable to session fixation attacks.

Upgrade available Upgrade to 3.08.03 or later
Fixed in 3.08.03
Interim mitigation

Implement session ID regeneration (rotation) upon successful authentication and invalidate any session IDs established prior to login. Additionally, bind sessions to additional factors like IP address or implement secure session token generation using cryptographically random values.

Recommended fix High confidence

Firmware version 3.08.03

  1. Identify the specific model number of the affected device (Aspect Ent 2, Aspect Ent 256, Aspect Ent 96, Nexus 2128, Nexus 2128 A, Nexus 2128 F, Nexus 2128 G, or Nexus 264)
  2. Access ABB's official support portal at search.abb.com and locate the firmware download section for your specific device model
  3. Download firmware version 3.08.03 (or latest available) from ABB's official support site
  4. Review the firmware upgrade instructions provided by ABB for your specific device model
  5. Connect to the device management interface via a secure, trusted network
  6. Create a backup of the current device configuration if the backup feature is available
  7. Upload and install the firmware version 3.08.03 following ABB's documented upgrade procedure
  8. After upgrade completes, verify the firmware version shows 3.08.03 in the device management interface
Caveat Review ABB release notes for version 3.08.03 to check for any configuration or compatibility changes before upgrading
