Executive Summary

This vulnerability is a Cross-Site Request Forgery (CSRF) flaw in the Syllabus-Aligned Learning Management & Examination System version 1.0. It allows attackers to perform unauthorized state-changing actions on behalf of authenticated users by exploiting missing CSRF protections such as anti-CSRF tokens, SameSite cookie attributes, and header validations.

Detection Guidance

Detecting CSRF vulnerabilities typically involves checking for missing anti-CSRF tokens, SameSite cookie attributes, and validating Origin/Referer headers. Review web application logs for suspicious state-changing requests (e.g., GET requests for deletions or modifications). Use browser developer tools to inspect network traffic for predictable token patterns or absence of security headers.

Mitigation Strategies

Implement anti-CSRF tokens for all state-changing operations. Convert GET requests to POST for critical actions. Set SameSite cookie attributes to Strict or Lax. Add Origin/Referer header validation. Ensure custom request headers are checked. These steps prevent unauthorized state changes and mitigate CSRF risks.
