Technical Analysis

This Red Hat security advisory covers two vulnerabilities in the Apache HTTP Server 2.4 packages for Red Hat Enterprise Linux 8.6. CVE-2025-55753 affects the mod_md module, causing unintended retry intervals which could impact the ACME protocol handling. CVE-2025-58098 affects the Server Side Includes feature, where query strings are added to the #exec cmd directive unexpectedly. Red Hat has released updated packages to fix these issues as part of their security update RHSA-2026:0011. The advisory rates the security impact as Important but does not provide CVSS scores. The affected products include multiple Red Hat Enterprise Linux 8.6 variants across x86_64 and ppc64le architectures.

Potential Impact

The vulnerabilities affect the mod_md module and Server Side Includes functionality of Apache HTTP Server 2.4 on Red Hat Enterprise Linux 8.6. The mod_md issue involves unintended retry intervals that could affect ACME certificate management processes. The Server Side Includes vulnerability involves improper handling of query strings in the #exec cmd directive, potentially leading to unintended command execution contexts. Red Hat rates the overall security impact as Important, indicating a significant but not critical risk. No known exploits in the wild have been reported at this time.

Mitigation Recommendations
