CVE-2015-2091 describes a critical authentication bypass vulnerability in mod-gnutls versions 0.5.10 and earlier, affecting Apache web servers configured with this module. Despite GnuTLSClientVerify being set to "require," the authentication hook fails to properly validate client certificates, allowing remote attackers to spoof legitimate clients using crafted certificates. This vulnerability has a CVSS score of 5.0, indicating a medium severity, with low attack complexity and potential for unauthorized access (integrity impact). While no active exploitation, exploit code, or significant community discussion has been observed, the flaw could lead to unauthorized access to resources protected by client certificate authentication.
