CVE-2026-45575
Improper Verification of Cryptographic Signature in com.oviva.telematik:epa4all-client
描述
### 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 ri_puk_idp_enc and uri_puk_idp_sig 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](https://github.com/oviva-ag/epa4all-client/pull/36) ### Workarounds None. ### Resources - MS-OVIVA-EPA4ALL-d453c1 ### Credits [Machine Spirits](https://machinespirits.com/) ([contact@machinespirits.de](mailto:contact@machinespirits.de)) - Dr. rer. nat.
