CVE-2026-44185: CWE-126 Buffer Over-read in Apache Software Foundation Apache HTTP Server
Buffer Over-read vulnerability in Apache HTTP Server via outbound OCSP requests to an attacker controlled OCSP server This issue affects Apache HTTP Server: from 2.4.0 through 2.4.67. Users are recommended to upgrade to version 2.4.68, which fixes the issue.
AI Analysis
Technical Summary
This vulnerability involves a buffer over-read (CWE-126) in the Apache HTTP Server when it processes outbound OCSP (Online Certificate Status Protocol) requests. Specifically, if the server communicates with a malicious OCSP responder, it may read beyond the intended buffer boundaries, potentially leading to information disclosure or application instability. The affected versions range from 2.4.0 up to 2.4.67. The Apache Software Foundation recommends upgrading to version 2.4.68, which contains the fix for this issue.
Potential Impact
The vulnerability could allow an attacker controlling an OCSP server to cause the Apache HTTP Server to read memory beyond allocated buffers during OCSP response processing. This may result in information disclosure or server instability. However, no known exploits are reported in the wild, and the impact is limited to scenarios where the server makes outbound OCSP requests to a malicious OCSP responder.
Mitigation Recommendations
Users should upgrade Apache HTTP Server to version 2.4.68, which fixes this buffer over-read vulnerability. Since this is an official fix from the vendor, applying the update is the recommended remediation. Patch status is confirmed by the vendor advisory recommending the upgrade. No additional mitigations are specified.
