🔍 How to Verify
Check if Vulnerable:
Test the login endpoint with a malicious redirect_url parameter (e.g., http://example.com/login?redirect_url=http://evil.com) and check if it redirects.Check Version:
Check the project's pom.xml or build.gradle for version information, or inspect the application's metadata.Verify Fix Applied:
After applying fixes, retest with the same malicious redirect_url to ensure no redirect occurs or only to allowed domains.📡 Detection & Monitoring
Log Indicators:
- Log entries showing redirects to external domains from the login endpoint, especially with unusual redirect_url values.
Network Indicators:
- HTTP 302 redirect responses from /login to non-whitelisted domains in network traffic.
SIEM Query:
source="web_logs" AND url_path="/login" AND response_code=302 AND redirect_url NOT IN ("allowed-domain1.com", "allowed-domain2.com")
