Red Hat Certificate System 10
Monthly
Server-side request forgery in Dogtag PKI's ACME responder enables unauthenticated ACME account holders to direct the certificate server to make arbitrary HTTP GET requests to internal network addresses. The validator incorrectly accepts IP address literals as valid DNS identifiers and follows HTTP redirects without enforcing RFC-compliant public-address filtering, allowing internal network reconnaissance. When the InMemory database backend is in use, the response body returned by internal services is exposed to the attacker through ACME challenge error messages, compounding the confidentiality impact. No public exploit code or active exploitation has been identified at time of analysis.
Authorization bypass in Red Hat Certificate System's CA renewal path allows an authenticated user to renew a certificate belonging to a different realm without the required realm-based authorization check. Affects versions 9, 10, and 11 of the Certificate System on Red Hat Enterprise Linux 6 through 10. No evidence of active exploitation or public exploit code exists at the time of analysis, and EPSS probability is low (0.21%).
