Apache HTTP Server Vulnerabilities Lead to Potential Denial of Service and Code Execution

The Apache HTTP Server has critical vulnerabilities related to ACME certificate renewals and Server Side Includes (SSI). Specifically, CVE-2025-55753 allows repeated renewal attempts without delays, potentially causing a denial of service, while CVE-2025-58098 permits arbitrary code execution through improperly handled query strings. Affected systems include those using Apache with SSI enabled and mod_cgid.
