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
In ABB SREA-01 revisions A, B, C: application versions up to 3.31.5, and SREA-50 revision A: application versions up to 3.32.8, an attacker may access internal files of ABB SREA-01 and SREA-50 legacy remote monitoring tools without any authorization over the network using a HTTP request which refers to files using ../../ relative paths. Once the internal password file is retrieved, the password hash can be identified using a brute force attack. There is also an exploit allowing running of commands after authorization.

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 · high confidence

Path traversal vulnerability in ABB SREA-01 and SREA-50 remote monitoring tools allows unauthenticated attackers to access internal files via HTTP requests containing ../../ directory traversal sequences. Successful exploitation exposes the password file, enabling offline brute-force cracking of password hashes and subsequent command execution.

MitigationUpgrade ABB SREA-01 to version 3.31.5+ and SREA-50 to version 3.32.8+. If patching is not feasible immediately, restrict network access to these devices and implement Web Application Firewall rules to block directory traversal patterns.

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 the device model
    Access the device's web interface or check device documentation to confirm the model is ABB SREA-01 or SREA-50 remote monitoring tool
    Affected if The device is an ABB SREA-01 or SREA-50 model
  2. Check the firmware version
    Log into the device's web interface or check the device administration page to find the installed firmware version
    Affected if The firmware version is 3.32.8 or lower for SREA-50, or 3.31.5 or lower for SREA-01
  3. Verify HTTP web interface is enabled
    Attempt to access the device's IP address via HTTP on the standard web port (typically 80 or 443) to confirm the web interface is reachable
    Affected if The HTTP web interface is exposed and accessible on the network
  4. Test for path traversal vulnerability
    Send an HTTP GET request to the device using a directory traversal pattern such as ../../../../etc/passwd or ../../../../etc/shadow to attempt to access internal system files
    Affected if The request returns contents of internal system files instead of being blocked or returning an error

A user is affected if they have an ABB SREA-01 or SREA-50 device with firmware at or below the affected versions and the HTTP web interface is accessible, as the path traversal vulnerability allows unauthenticated access to internal files including password data.

From vendor data
Upgrade available Upgrade to a release after 3.32.8
Interim mitigation

Upgrade ABB SREA-01 to version 3.31.5+ and SREA-50 to version 3.32.8+. If patching is not feasible immediately, restrict network access to these devices and implement Web Application Firewall rules to block directory traversal patterns.
