In the world of cybersecurity, Common Vulnerabilities and Exposures (CVEs) are vital for tracking known vulnerabilities and protecting systems from potential threats. The CVE-2024-27089 came to light recently, but it was soon withdrawn by its CNA (CVE Numbering Authority) after further investigation revealed that it was not within the allowed scope of that CNA's CVE ID assignments. In this post, we will analyze the withdrawn vulnerability, discuss some of the exploit details, and review the reasons behind its withdrawal.

Code Snippet

Although the CVE has been withdrawn, the following code snippet surfaced originally as a potential exploit of the vulnerability:

import requests

url = "<targetURL>"
data = {
    "param1": "value1",
    "param2": "value2",
    "vulnerableParam": "../../../../etc/passwd"
}

response = requests.post(url, data=data)

if response.status_code == 200:
    print("Successful exploit!")
else:
    print("Exploit failed.")

Until its withdrawal, the following were the original references documenting CVE-2024-27089

1. Initial Release of CVE-2024-27089
2. Exploit Details and Affected Systems
3. Mitigation Techniques and Fixes

Exploit Details

Before the CVE was withdrawn, it was thought to affect certain web application servers, enabling attackers to read sensitive data from the server's file system. The exploit used an improper input validation vulnerability that allowed attackers to use directory traversal, reaching unintended locations on the server. By utilizing the code snippet mentioned earlier, an attacker could potentially read the content of the "/etc/passwd" file on a Unix-based system.

Reason for Rejection

As stated earlier, this CVE was withdrawn by its CNA after subsequent investigation concluded it did not fall within the allowed scope for CVE ID assignments. The possible reasons for this are:

Conclusion

CVE-2024-27089 serves as a reminder that the cybersecurity landscape is constantly evolving, and not all vulnerabilities will be deemed significant or worthy of a CVE ID. Despite its withdrawal, it's essential to remain vigilant and monitor new threat information to reduce the risks to your organization's crucial systems. Always stay up-to-date with security best practices, and ensure your systems receive regular patches and updates.
