CVE-2024-56571 - Rejected CVE Explained

Not all Common Vulnerabilities and Exposures (CVEs) are created equal. Sometimes, a CVE gets public attention only to be later rejected or withdrawn by the official authorities, leaving developers and security teams wondering what happened. Today, we'll take a deep dive into CVE-2024-56571, a CVE that was assigned but ultimately rejected. We'll explain what that means, show what might have been in sample code (for illustration), and help you understand why some CVEs never make it to your patch queue.

What is CVE-2024-56571?

*CVE-2024-56571* was a tracking number initially assigned to a supposed vulnerability. Here is the official caveat, straight from the sources:

> REJECTED: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. Further use of this CVE ID is considered invalid, and any references or claims to this number should not be treated as describing a genuine vulnerability.

Read the official statement on MITRE’s CVE directory.

There are a few main reasons why a CVE gets rejected

- False positive: Someone thought they found a vulnerability, but it turned out to be a false alarm.

Not a vulnerability: After review, the problem was deemed not to affect security.

- Reporter request: The original reporter withdraws their request, perhaps after internal reassessment.

What Was Supposedly Involved in CVE-2024-56571?

Because CVE-2024-56571 was rejected, no official technical information—like affected products, attack vectors, or patch instructions—was published. Sometimes, contributors speculate about what a rejected CVE might have covered. While we don’t recommend chasing rumors, here’s a generic (NOT REAL) example of code that sometimes leads to confusion over vulnerabilities:

# Example: A common false positive in Python web apps

import os
from flask import Flask, request

app = Flask(__name__)

@app.route('/run')
def run_cmd():
    cmd = request.args.get('cmd')
    # False positive: assumed to be vulnerable, but only allowed for authenticated users
    if cmd and user_is_admin():  # <-- Proper check
        os.system(cmd)
    return 'Command executed or access denied'

Security scanners might flag this as a command injection, but if proper authentication guards the dangerous functionality, it may be by design, not a vulnerability.

Before reacting to a headline or rushing a patch, check

- The official CVE site for status (Rejected = not real)
- NVD or vendor advisories for confirmation

Change logs or security bulletins from software authors

If a CVE is marked as REJECTED on official sources, you can ignore any exploits, PoC code, or patch requests referencing it.

Exploit Details: None Available

Since CVE-2024-56571 was officially rejected, no official exploits, proof-of-concept code, or attack vectors are available or valid. Any third-party posts or “PoC” scripts you see are at best speculation, and at worst, outright misinformation.

CVE-2024-56571 is NOT a real vulnerability.

- Official sources MITRE and NVD both say it’s REJECTED.
