CVE-2024-12698 is a new security vulnerability that impacts the ose-olm-catalogd-container, a component commonly used in various modern systems. This vulnerability stems from an incomplete fix for the previously disclosed Rapid Reset Vulnerability (CVE-2023-39325/CVE-2023-44487), where only unauthenticated streams were protected while leaving streams created by authenticated sources vulnerable.

In this post, we will discuss the details of this vulnerability, its impact on affected systems, and the code snippet that demonstrates how the incomplete fix still allows for exploitation. Lastly, we will provide links to original references and further information on how to mitigate this threat.

Vulnerability Details

The ose-olm-catalogd-container component was previously affected by the Rapid Reset vulnerability. This allowed remote attackers to exhaust resources by sending malicious requests to exploit unauthenticated streams. The vendors of the component released a patch to address this issue, but unfortunately, the fix was incomplete. Authenticated streams remained vulnerable, allowing attackers who managed to authenticate with the target system to carry out the same resource exhaustion attack.

The severity of this vulnerability (CVE-2024-12698) is considered Medium, as it requires attackers to first authenticate with the target system. However, its impact can still be significant, leading to denial of service (DoS) attacks and causing systems to become unresponsive.

Code Snippet

The following code snippet demonstrates the incomplete fix that only addresses unauthenticated streams:

def handle_request(request):
    if request.is_authenticated():
        # The security patch only validates unauthenticated requests,
        # leaving authenticated streams vulnerable.
        pass
    else:
        # Here, the unauthenticated stream is checked and limited.
        rate_limit_unauthenticated(request)

    process_request(request)

As seen in the code, the rate_limit_unauthenticated function is only called for unauthenticated requests. Authenticated requests bypass this check, allowing attackers to continue exploiting the vulnerability.

Mitigation

To effectively protect your systems from this vulnerability, it is essential to apply a comprehensive security patch addressing both authenticated and unauthenticated streams. Organizations should monitor their vendors for updates on this vulnerability and apply patches accordingly. Additionally, implementing proper authentication and rate-limiting measures for all streams, whether authenticated or not, can further safeguard against potential threats.

Conclusion

CVE-2024-12698 is a critical vulnerability that highlights the importance of thorough security fixes. The incomplete fix for ose-olm-catalogd-container not only leaves systems exposed, but it also underscores how even seemingly patched vulnerabilities can continue to pose significant risks. To protect against this vulnerability and potential future threats, implement robust security measures and keep abreast of new vulnerabilities and patches.
