Summary

Improper Verification of Cryptographic Signature in com.oviva.telematik:epa4all-client

Details

Impact

An attacker who can MITM the TLS connection between the client and the IDP (within the TI network) can substitute a forged discovery document. The forged document redirects u ripukidpenc and uripukidpsig to attacker-controlled URLs. The client then encrypts the SMC-B-signed challenge response to the attacker's encryption key and POSTs it to the attacker's auth endpoint. This captures the signed authentication material.

Patches

#36

Workarounds

None.
