  "details" : [ "In Dogtag PKI through 10.8.3, the pki.client.PKIConnection class did not enable python-requests certificate validation. Since the verify parameter was hard-coded in all request functions, it was not possible to override the setting. As a result, tools making use of this class, such as the pki-server command, may have been vulnerable to Person-in-the-Middle attacks in certain non-localhost use cases. This is fixed in 10.9.0-b1.", "A flaw was found in PKI, where the dogtag's pki.client.PKIConnection class disables the python-requests certificate validation. This flaw allows an attacker to intercept a connection between a FreeIPA client and a server, and execute an active Man-in-the-Middle attack. The highest threat from this vulnerability is to confidentiality and integrity." ],
  "statement" : "In PKI, the pki.client.PKIConnection python class is used by the `pki-server` and `pkispawn` commands. `pki-server` runs locally on the server, thus not subject to a Person in the Middle attack. `pkispawn` may access remote node in decentralized or cloned contexts.\nIdentity Management (IPA) command line interface (the vault related sub-commands) may call pki.client.PKIConnection().",
