CVSS: 6.5EPSS: 0%CPEs: 5EXPL: 0CVE-2023-1664 – keycloak: Untrusted Certificate Validation
https://notcve.org/view.php?id=CVE-2023-1664
A flaw was found in Keycloak. This flaw depends on a non-default configuration "Revalidate Client Certificate" to be enabled and the reverse proxy is not validating the certificate before Keycloak. Using this method an attacker may choose the certificate which will be validated by the server. If this happens and the KC_SPI_TRUSTSTORE_FILE_FILE variable is missing/misconfigured, any trustfile may be accepted with the logging information of "Cannot validate client certificate trust: Truststore not available". This may not impact availability as the attacker would have no access to the server, but consumer applications Integrity or Confidentiality may be impacted considering a possible access to them. • https://bugzilla.redhat.com/show_bug.cgi?id=2182196&comment#0 https://access.redhat.com/security/cve/CVE-2023-1664 https://bugzilla.redhat.com/show_bug.cgi?id=2182196 • CWE-295: Improper Certificate Validation •
CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 0CVE-2022-4492 – undertow: Server identity in https connection is not checked by the undertow client
https://notcve.org/view.php?id=CVE-2022-4492
The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol. A flaw was found in undertow. The undertow client is not checking the server identity the server certificate presents in HTTPS connections. • https://access.redhat.com/security/cve/CVE-2022-4492 https://bugzilla.redhat.com/show_bug.cgi?id=2153260 https://security.netapp.com/advisory/ntap-20230324-0002 • CWE-550: Server-generated Error Message Containing Sensitive Information •
