The HTTP Request Smuggling vulnerability in Qlik Sense Enterprise allows attackers to bypass security measures and perform unauthorized actions by exploiting the way the application parses HTTP requests. This vulnerability occurs when ambiguous requests are processed by the server in a manner that enables an attacker to insert additional requests into the server's request queue. It can lead to various security issues, including privilege escalation, unauthorized data access, and execution of malicious commands. This vulnerability requires immediate attention due to its potential impact on data integrity and system security.

The vulnerability exploits specific endpoints in the Qlik Sense Enterprise software that inadequately handle HTTP request parsing. Attackers can smuggle HTTP requests by manipulating the 'Content-Length' and 'Transfer-Encoding' headers, causing the server to misinterpret the boundary between separate HTTP requests. This manipulation can allow attackers to inject malicious requests or commands that are executed by the backend server, compromising the application's security. The vulnerable endpoints and parameters are critical components of the Qlik Sense Enterprise infrastructure, making them prime targets for exploitation.

Exploitation of the HTTP Request Smuggling vulnerability could lead to several adverse effects, including unauthorized access to sensitive data, elevation of privileges, and the ability to execute arbitrary code on the server. Attackers might also disrupt the normal operation of the application, leading to denial of service. The vulnerability exposes the system to potential data breaches, compromising the confidentiality, integrity, and availability of the data processed by Qlik Sense Enterprise.
