Attack-Flow Graph

Executive Summary

This vulnerability exists in PHPEMS version 11.0, specifically in the function temppage within the file /app/exam/controller/exams.master.php, which is part of the Instant Exam Creation Handler component.

The issue arises from the manipulation of the argument 'uploadfile', which leads to a server-side request forgery (SSRF). This means an attacker can make the server send unauthorized requests to other internal or external resources.

The attack can be executed remotely, and the exploit code is publicly available.

Impact Analysis

This vulnerability can allow an attacker to perform server-side request forgery, which may enable them to access or interact with internal systems or services that are not normally exposed.

Such unauthorized requests could lead to information disclosure, unauthorized actions within the internal network, or further exploitation depending on the internal services accessible.

Because the exploit is publicly available and the attack can be performed remotely, the risk of exploitation is increased.
