Unauthenticated service takeover via hardcoded JWT secret
Published Nov 13, 2024 · Updated Nov 21, 2024
Authentication bypass in FIT2CLOUD DataEase before 2.10.2 allows remote attackers to forge administrator JWTs and access the service. SubstituleLoginServer signs tokens with HMAC-SHA256 using a hardcoded secret while assigning the fixed uid and oid values 1, enabling independently generated tokens to pass verification. No credentials or user interaction are required, and a forged token grants administrator-context access to protected data and service functions.
