Hi, The following vulnerability was published for freeipa. CVE-2024-2698[0]: | A vulnerability was found in FreeIPA in how the initial | implementation of MS-SFU by MIT Kerberos was missing a condition for | granting the "forwardable" flag on S4U2Self tickets. Fixing this | mistake required adding a special case for the | check_allowed_to_delegate() function: If the target service argument | is NULL, then it means the KDC is probing for general constrained | delegation rules and not checking a specific S4U2Proxy request. | In FreeIPA 4.11.0, the behavior of ipadb_match_acl() was modified to | match the changes from upstream MIT Kerberos 1.20. However, a | mistake resulting in this mechanism applies in cases where the | target service argument is set AND where it is unset. This results | in S4U2Proxy requests being accepted regardless of whether or not | there is a matching service delegation rule. https://bugzilla.redhat.com/show_bug.cgi?id=2270353 If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
