CVE-2017-3167: ap_get_basic_auth_pw authentication bypass Severity: Important Vendor: The Apache Software Foundation Versions Affected: httpd 2.2.0 to 2.2.32 httpd 2.4.0 to 2.4.25 Description: Use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed. Mitigation: 2.2.x users should either apply the patch available at https://www.apache.org/dist/httpd/patches/apply_to_2.2.32/CVE-2017-3167.patch or upgrade in the future to 2.2.33, which is currently unreleased. 2.4.x users should upgrade to 2.4.26. Third-party module writers SHOULD use ap_get_basic_auth_components(), available in 2.2.33 and 2.4.26, instead of ap_get_basic_auth_pw(). Modules which call the legacy ap_get_basic_auth_pw() during the authentication phase MUST either immediately authenticate the user after the call, or else stop the request immediately with an error response, to avoid incorrectly authenticating the current request.
