CVE-2026-48005: CWE-306 Missing authentication for critical function in Apache Software Foundation Apache HTTP Server
Missing authentication checks in mod_auth_digest in Apache Software Foundation Apache HTTP Server before 2.4.69 on all platforms allows an unauthenticated remote client to cause a denial of service (forced re-authentication) via forged Authorization headers when Digest authentication is enabled with AuthDigestNcCheck . Users are recommended to upgrade to version 2.4.69, which fixes this issue.
AI Analysis
Technical Summary
This vulnerability (CWE-306) affects Apache HTTP Server versions 2.4.0 through 2.4.68. The mod_auth_digest module lacks proper authentication checks for critical functions, enabling unauthenticated remote attackers to trigger a denial of service condition by sending forged Authorization headers. This forces legitimate users to re-authenticate repeatedly when Digest authentication with AuthDigestNcCheck is enabled. The Apache Software Foundation has addressed this issue in version 2.4.69.
Potential Impact
An unauthenticated remote attacker can cause a denial of service by forcing repeated re-authentication requests, potentially disrupting legitimate user access to the Apache HTTP Server when Digest authentication is enabled with AuthDigestNcCheck.
Mitigation Recommendations
Users should upgrade Apache HTTP Server to version 2.4.69 or later, where this vulnerability is fixed. No other mitigations are specified.
