Detailsinfo

A vulnerability was found in linqi 504. It has been rated as critical. Affected by this issue is an unknown function of the component Custom Process Creation Feature. The manipulation with an unknown input leads to a server-side request forgery vulnerability. Using CWE to declare the problem leads to CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. Impacted is confidentiality, integrity, and availability. CVE summarizes:

A Server-Side Request Forgery (SSRF) vulnerability in the custom process creation feature of linqi allows an authenticated attacker to probe internal network components. By crafting a specific process containing an HTTP Request component, an attacker can force the server to send arbitrary HTTP requests. By observing the varying application responses (Success, Failed, or 504 Gateway Time-out), the attacker can determine the status of internal ports, leading to internal network reconnaissance.
