Technical details
HCL Aftermarket EPC version 1.0.0 is vulnerable to Host header poisoning due to improper input validation (CWE-20) of the HTTP Host header. The application accepts arbitrary hostnames provided in the header when communicating via the HTTP protocol. A remote, unauthenticated attacker can exploit this by sending a specially crafted request to the server. Successful exploitation can lead to various attacks, including web cache poisoning, password reset poisoning, or bypassing security controls that rely on the Host header for routing or domain-specific logic. The vulnerability is confirmed in version 1.0.0.
