CVE-2023-41265 is an HTTP request tunneling vulnerability in Qlik Sense Enterprise for Windows. The flaw affects the product’s proxy-to-backend request handling and arises from inconsistent parsing of HTTP messages between the front-end proxy and backend services when both Content-Length and Transfer-Encoding are present. The proxy is described as forwarding based on Content-Length while also forwarding Transfer-Encoding, creating a request smuggling/tunneling condition. Because backend services trust proxy-injected identity headers on the internal channel, a tunneled request can bypass proxy header restrictions and impersonate privileged internal identities. In practical exploitation, this enables attacker-controlled requests to reach backend repository functionality that would not normally be directly accessible, including administrative APIs. Public research indicates the issue can be chained with CVE-2023-41266 to achieve unauthenticated remote code execution, including abuse of the repository application’s external program task functionality to execute arbitrary commands.
