The X.509 certificate chain used by this service contains certificates with RSA keys that may have been improperly generated.
At least one of the X.509 certificates sent by the remote host has an RSA key that appears to be generated improperly, most likely by a TPM (Trusted Platform Module) produced by Infineon Technologies. A third party may be able to recover the private key from the certificate's public key. This may allow an attacker to impersonate an HTTPS website or decrypt SSL/TLS sessions to the remote service.
Upgrade the firmware for all Infineon TPMs and revoke the affected certificates, including any certificates signed by an affected key.
