CVE-2025-46178 is a cross-site scripting (XSS) vulnerability in the CloudClassroom PHP Project. The issue exists in askquery.php and is triggered via the eid parameter, which is insufficiently validated or encoded before being reflected into a web response. An attacker can craft a malicious URL containing JavaScript payloads in the eid parameter and cause that script to execute in the security context of a victim's browser when the victim visits the link.

This repository provides a proof-of-concept (POC) exploit for a reflected Cross-Site Scripting (XSS) vulnerability (CVE-2025-46178) in the CloudClassroom PHP Project version 1.0. The vulnerability exists in the 'askquery.php' file, specifically in the handling of the 'eid' GET parameter, which is not properly sanitized before being rendered in the frontend HTML. The exploit demonstrates that an attacker can craft a URL containing a malicious JavaScript payload (e.g., <ScRiPt >alert(9734)</ScRiPt>) in the 'eid' parameter. When a victim visits this URL, the script executes in their browser, potentially leading to session hijacking or website defacement. The repository consists of two files: a detailed exploit description and a README.md, both outlining the vulnerability, affected component, attack vector, and mitigation recommendations. No actual exploit code is present; the POC is the crafted URL and payload. The main fingerprintable endpoint is the vulnerable 'askquery.php' file accessible via HTTP.
