The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0799 advisory.
guava: insecure temporary directory creation (CVE-2023-2976)
keycloak: reflected XSS via wildcard in OIDC redirect_uri (CVE-2023-6134)
keycloak: redirect_uri validation bypass (CVE-2023-6291)
keycloak: Log Injection during WebAuthn authentication or registration (CVE-2023-6484)
keycloak: open redirect via form_post.jwt JARM response mode (CVE-2023-6927)
jetty-server: OutOfMemoryError for large multipart without filename read via request.getParameter() (CVE-2023-26048)
jetty-server: Cookie parsing of quoted values can exfiltrate values from other cookies (CVE-2023-26049)
santuario: Private Key disclosure in debug-log output (CVE-2023-44483)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
