Summary
HCL BigFix Service Management is susceptible to HTTP Request Smuggling. HTTP request smuggling vulnerabilities arise when websites route HTTP requests through web servers with inconsistent HTTP parsing. HTTP Smuggling exploits inconsistencies in request parsing between front-end and back-end servers, allowing attackers to bypass security controls and perform attacks like cache poisoning or request hijacking.
