Kerberos
Monthly
Authentication bypass in the Keycloak (Red Hat Build of Keycloak) Kerberos federation provider lets an attacker on the same or adjacent network impersonate the Key Distribution Center and bypass Kerberos password authentication, potentially gaining unauthorized access to user accounts. The flaw only manifests in the specific, non-default configuration where Kerberos PASSWORD authentication is used while SPNEGO is disabled, because that mode never requests a server ticket to verify the KDC's identity. Rated CVSS 3.1 6.8 (AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N), exploitation requires network adjacency and an active on-path spoofing operation; no public exploit code has been identified and the CVE has not been listed as confirmed actively exploited (CISA KEV).
The kerberos package before 1.0.0 for Node.js allows arbitrary code execution and privilege escalation via injection of malicious DLLs through use of the kerberos_sspi LoadLibrary() method, because. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
A Reachable Assertion issue was discovered in the KDC in MIT Kerberos 5 (aka krb5) before 1.17. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable.
An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
In MIT Kerberos 5 (aka krb5) 1.7 and later, an authenticated attacker can cause a KDC assertion failure by sending invalid S4U2Self or S4U2Proxy requests. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity.
plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service. Rated low severity (CVSS 3.5), this vulnerability is remotely exploitable. No vendor patch available.
MIT Kerberos 5 (aka krb5) 1.7.x through 1.12.x before 1.12.2 allows remote attackers to cause a denial of service (buffer over-read or NULL pointer dereference, and application crash) by injecting. Rated medium severity (CVSS 5.0), this vulnerability is remotely exploitable, low attack complexity. This Buffer Overflow vulnerability could allow attackers to corrupt memory to execute arbitrary code or crash the application.
An unspecified third-party database module for the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.10.x allows remote authenticated users to cause a denial of service (NULL pointer. Rated medium severity (CVSS 4.0), this vulnerability is remotely exploitable, low attack complexity.
