Authentication bypass via hardcoded JWT signing key
Published Oct 24, 2023 · Updated Sep 17, 2024
Hardcoded credentials in Dromara Sureness before 1.0.8 allow remote attackers to forge JWTs with the default signing key. JsonWebTokenUtil initializes secretKey from the constant DEFAULT_SECRET_KEY, then uses that shared key to create and verify tokens. Exploitation requires a deployment that retains the default key; accepted forged claims can bypass the consuming application's authentication and authorization controls.
