Hi! A FakeBasicAuth authentication bypass issue was reported for mod_nss some time ago: https://www.redhat.com/archives/mod_nss-list/2011-May/msg00001.html The issue was fixed in upstream git: https://git.fedorahosted.org/cgit/mod_nss.git/commit/?id=a6c3370491ae1d3bc552e8de9353c82f73e510e3 but there was no new release of mod_nss since to include the fix. The issue now got CVE-2011-4973 assigned. Note that the fix changes the user name that needs to be specified in htpasswd when using FakeBasicAuth. -- Tomas Hoger / Red Hat Security Response Team
