CVE-2024-4601
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 · uneditedAn incorrect authentication vulnerability has been found in Socomec Net Vision affecting version 7.20. This vulnerability allows an attacker to perform a brute force attack on the application and recover a valid session, because the application uses a five-digit integer value.
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 Socomec Net Vision web application uses a five-digit integer (10000-99999, only 90,000 possible values) for session identification. This extremely limited key space allows attackers to brute force valid session IDs and hijack authenticated user sessions.

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 Socomec Net Vision installationCheck for the Net Vision web application in your environment by reviewing installed software, web server configurations, or network services listening on typical ports (HTTP/HTTPS). Look for 'NetVision' or 'Socomec' in service banners or application documentation.Affected if Socomec Net Vision web application is present in the environment
-
Inspect session token formatLog into the Net Vision web interface and examine the session cookie or session identifier using browser developer tools, a proxy interceptor, or by capturing HTTP requests. Look for the session ID value in cookies, headers, or URL parameters.Affected if The session ID appears as a five-digit integer (numeric only, 5 characters)
-
Measure session ID entropyGenerate or capture multiple session IDs by logging in repeatedly. Count the number of unique characters used and measure the total length of each session ID.Affected if Session IDs are exactly 5 digits long using only numeric characters (10000-99999 range)
-
Assess session ID key spaceCalculate the total number of possible unique session IDs. For a five-digit decimal integer, this is 90,000 possible values (99999 - 10000 + 1). Compare this against recommended cryptographic standards (minimum 128 bits of entropy).Affected if The total pool of possible session IDs is 90,000 or fewer unique values
Your environment is affected if the Socomec Net Vision web application is running and uses session IDs that are five-digit integers (10000-99999), creating a small key space vulnerable to brute force attacks.

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 dataReplace the five-digit integer with a cryptographically secure random session token of sufficient length (minimum 128 bits). Implement rate limiting and account lockout mechanisms to prevent brute force attempts.
