CVE-2025-7773
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 · uneditedA security issue exists within the 5032 16pt Digital Configurable module’s web server. The web server’s session number increments at an interval that correlates to the last two consecutive sign in session interval, making it predictable.
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 5032 16pt Digital Configurable module's web server generates session IDs in a predictable manner. The session number increment correlates with the last two consecutive sign-in session intervals, allowing an attacker to potentially predict valid session IDs and perform session hijacking attacks.

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 5032 16pt Digital Configurable moduleLocate and confirm the presence of this specific hardware module and its embedded web server interface. Check device inventory or network scans for the module's IP address or hostname.Affected if The module with its web server interface is present and accessible on the network
-
Access the web server login interfaceOpen a browser and navigate to the web interface of the 5032 module. Attempt to log in and capture the session cookie or session identifier that is generated upon authentication.Affected if The web interface is accessible and returns a session ID cookie or parameter
-
Analyze session ID format and patternsPerform multiple login attempts from the same or different IP addresses. Capture and compare the generated session IDs to identify any sequential, time-based, or incremental patterns.Affected if Session IDs increment predictably or correlate to login timestamps/sequence numbers
-
Test session ID predictabilityAfter obtaining one valid session ID, attempt to predict and use subsequent or preceding session IDs to access the system without authentication.Affected if Predicted or enumerated session IDs grant unauthorized access to the application
-
Check session ID entropyExamine the session ID length and character distribution. Determine if the ID uses sufficient randomness or relies on simple numeric counters.Affected if Session IDs are short, numeric-only, or lack cryptographic randomness
A user is affected if the 5032 16pt Digital Configurable module web server is running and produces session IDs that can be predicted, enumerated, or correlated to prior session intervals.

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 cryptographically secure random session ID generation that eliminates any correlation with previous session intervals or login patterns.
