CVE-2025-3037 Overview
CVE-2025-3037 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] identified in the yzk2356911358 StudentServlet-JSP project. The affected commits are cc0cdce25fbe43b6c58b60a77a2c85f52d2102f5 and d4d7a0643f1dae908a4831206f2714b21820f991. An attacker can trigger the flaw remotely by inducing a victim to interact with attacker-controlled content. The project uses continuous delivery with rolling releases, so no fixed version identifiers are published. The exploit has been publicly disclosed.
Critical Impact
A remote attacker can perform state-changing actions in the context of an authenticated user without their consent, targeting the affected StudentServlet-JSP application over the network.

Technical Details for CVE-2025-3037
Vulnerability Analysis
The issue is a Cross-Site Request Forgery weakness [CWE-352] in the StudentServlet-JSP web application. The application processes state-changing HTTP requests without validating that the request was intentionally issued by the authenticated user. Because no anti-CSRF token, origin check, or equivalent control is enforced, any request accompanied by a valid session cookie is accepted as authentic. The attack requires user interaction, such as clicking a link or loading a malicious page, but no attacker privileges on the target system.
Root Cause
The servlet endpoints do not implement a synchronizer token, SameSite cookie protection, or verification of the Origin/Referer headers. The browser automatically attaches session cookies to cross-origin requests, so a forged POST or GET request executes with the victim's authority. This is a classic missing-control condition rather than a logic flaw in a specific handler.
Attack Vector
An attacker hosts a page containing an auto-submitting form or embedded resource that targets a sensitive StudentServlet-JSP endpoint. When an authenticated user visits the attacker-controlled page, the browser sends the request with the user's session cookies. The application processes the request as if the user initiated it, allowing unauthorized data creation, modification, or deletion. See the GitHub Issue Tracker and VulDB #302098 for reference details.
Detection Methods for CVE-2025-3037
Indicators of Compromise
- Web server access logs showing state-changing requests to StudentServlet-JSP endpoints with an external Referer header or missing Origin.
- Bursts of identical POST requests originating from different client IPs shortly after users visit unrelated third-party sites.
- Unexpected creation, modification, or deletion of student records without corresponding legitimate user activity.
Detection Strategies
- Instrument the servlet layer to log the Origin, Referer, and session identifier for every state-changing request and alert on cross-origin values.
- Deploy a web application firewall rule that flags authenticated POST requests lacking a valid anti-CSRF token.
- Correlate authentication events with subsequent write actions to detect requests that lack a preceding user-initiated navigation.
Monitoring Recommendations
- Baseline normal Referer domains for the application and alert on deviations.
- Monitor administrative and data-modification endpoints for anomalous request volume per session.
- Retain HTTP request metadata for at least 90 days to support post-incident CSRF investigations.
How to Mitigate CVE-2025-3037
Immediate Actions Required
- Restrict access to the StudentServlet-JSP application to trusted networks until CSRF controls are added.
- Configure session cookies with SameSite=Strict or SameSite=Lax and the Secure and HttpOnly attributes.
- Require users to re-authenticate before performing sensitive actions such as account or record modification.
Patch Information
No vendor patch or fixed release is available. The project uses continuous delivery with rolling releases, and the maintainer has not published an advisory identifying a corrected commit. Operators must implement CSRF protections themselves or migrate off the affected code. Track updates through the GitHub Issue #3 discussion.
Workarounds
- Add a synchronizer token pattern: generate a per-session random token, embed it in every form, and validate it server-side on each state-changing request.
- Enforce Origin and Referer header validation in a servlet filter, rejecting requests from unexpected domains.
- Place the application behind a reverse proxy or WAF that injects and validates CSRF tokens for legacy applications.
# Example servlet filter concept for CSRF token validation
# 1. On GET: issue token -> session attribute "csrfToken" and hidden form field
# 2. On POST: compare request parameter "csrfToken" against session value
# 3. Reject request with HTTP 403 if missing or mismatched
