CVE-2024-6515
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 · uneditedWeb browser interface may manipulate application username/password in clear text or Base64 encoding providing a higher probability of unintended credentails exposure. 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 confidenceThe ABB ASPECT Enterprise, NEXUS Series, and MATRIX Series web interfaces expose user credentials in clear text or Base64 encoding during authentication. Base64 is encoding, not encryption, making it trivial to decode exposed credentials. This allows attackers with network access to intercept and easily recover username/password pairs.

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 the firmware version of the ABB deviceAccess the device's web interface or administrative console and navigate to System Information, About, or Firmware Status to retrieve the installed firmware version numberAffected if The firmware version is lower than 3.08.03 for any of the following: ABB Aspect Enterprise (Ent 2, Ent 256, Ent 96), ABB Nexus 2128, 2128 A, 2128 F, 2128 G, or 264
-
Verify if the web interface is accessible over HTTPAttempt to access the device web interface using http:// (not https://) and observe whether the connection succeeds without TLS/SSL encryptionAffected if The web interface accepts HTTP connections on port 80 or other non-encrypted ports
-
Capture authentication traffic to inspect credential encodingUse a network packet capture tool (such as Wireshark or tcpdump) on the network segment between the client and the ABB device, then perform a login attempt and examine the HTTP POST request for the authentication endpointAffected if The login request body contains Base64-encoded strings that decode to username and password pairs, or credentials appear in clear text
-
Check if HTTPS/TLS is enforced for the authentication endpointInspect the web interface configuration or SSL/TLS settings page, or examine the HTTP response headers and initial connection to determine if TLS encryption is enabled and required for all authentication trafficAffected if TLS/SSL is not enabled, not properly configured, or credentials are transmitted over unencrypted channels
You are affected if your ABB device runs firmware version below 3.08.03 AND your web authentication traffic is transmitted over unencrypted HTTP or uses Base64 encoding without TLS protection.

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.
dbcve · scoped3.08.03
Implement TLS/SSL for all authentication traffic and replace Base64 encoding with proper cryptographic hashing and encryption for credential handling. Ensure credentials are never transmitted or stored in reversibly-encoded formats.
Firmware 3.08.03 for all affected ABB Aspect Enterprise and Nexus Series devices
- Identify the specific ABB product model (Aspect Ent 2, Aspect Ent 256, Aspect Ent 96, Nexus 2128, Nexus 2128 A, Nexus 2128 F, Nexus 2128 G, or Nexus 264)
- Access the device administrative interface or contact ABB support to obtain the firmware upgrade package
- Download firmware version 3.08.03 or later from ABB's official support portal (search.abb.com)
- Follow ABB's standard firmware upgrade procedure for the specific device model
- Verify the firmware version after upgrade confirms 3.08.03 or later
- Test that the web interface no longer transmits credentials in cleartext or Base64 encoding
