CyberRota Analysis
AI-GeneratedThe ePA 3.x Integration prior to version 1.3.0 is vulnerable due to improper handling of CRLF characters, allowing authenticated attackers to inject malicious headers into HTTP requests. This could lead to unauthorized access to patient records or bypassing of authentication mechanisms, posing a significant risk to patient privacy and data integrity. Organizations utilizing this integration should prioritize upgrading to version 1.3.0 to mitigate these vulnerabilities.

Original NVD Description
ePA 3.x Integration implements the authorization workflow and writes Medical Information Objects to Germany's electronic patient record. Prior to 1.3.0, ePA 3.x Integration does not neutralize CRLF characters in values used by app/vau/VAUProtokoll.py to construct VAU inner HTTP requests. The build_inner_header function interpolates the uri, host, accept_type, content_type, content_length, USER_AGENT, and insurant_id values into request lines and headers, including x-useragent and x-insurantid. An authenticated attacker who controls a value can inject additional headers into the inner request. Depending on ePA server handling, an injected x-insurantid header can expose another patient's records, and injected Authorization headers can bypass the intended authentication or authorization context. Session-derived USER_AGENT input can also poison requests across the session. This issue is fixed in version 1.3.0.
