    CVE-2005-2700

    Published: 6 Sept 2005Last Modified: 10 Apr 2026

    Summary:

    Details: ssl_engine_kernel.c in mod_ssl before 2.8.24, when using "SSLVerifyClient optional" in the global virtual host configuration, does not properly enforce "SSLVerifyClient require" in a per-location context, which allows remote attackers to bypass intended access restrictions.
