CyberRota Analysis
AI-GeneratedThe vulnerability affects epa4all versions prior to 2026-05-20, allowing attackers on the network path to exploit disabled TLS verification and present self-signed certificates, which can lead to man-in-the-middle (MITM) attacks. This enables unauthorized access to sensitive data and the ability to modify traffic, including smartcard operations and OIDC authentication exchanges. Organizations using affected versions of epa4all should prioritize updating to the patched version to mitigate these risks.

Original NVD Description
In epa4all, prior to version 2026-05-20, an attacker on the network path between epa4all and any backend (ePA Aktensystem, Konnektor, IDP, TSS) can present a self-signed TLS certificate and intercept the connection. For non-VAU connections (Konnektor, IDP), this allows direct read and modification of the inner traffic, including smartcard operations and OIDC authentication exchanges. For the ePA backend, the disabled TLS verification is the transport-level enabler for the VAU MITM described in GHSA-vvh7-x6c7-46gh. This issue has been patched in version 2026-05-20.
