9.8Critical

Attack vector: Network
Complexity: Low
Privileges needed: None
User interaction: None
Impact: Full C/I/A compromise
Weakness: CWE-321

Impact

Unauthenticated remote attackers can forge admin JWTs and gain full administrative access to protected /webapi routes, including the Doris SQL query API. All an attacker needs is network access to the web interface.

Root cause

The application relies on a hardcoded default HMAC secret in JwtTokenService and configuration files to sign and verify JWTs.

Affected systems

DataBuff ai-apm-web through 0.1.10

CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Fix & remediation

Upgrade to a fixed version beyond 0.1.10 once released. As an immediate workaround, override the default JWT secret in application.yml or via environment variables with a strong, random key and restart the service.

AI-suggested. Run it in staging first and check it against the vendor advisory. Why?

NVD description

DataBuff ai-apm-web through 0.1.10 contains an authentication bypass vulnerability that allows unauthenticated attackers to forge admin session tokens by using the hardcoded HMAC secret in JwtTokenService. Attackers can sign a payload of admin and a future expiry with the default dev-secret to gain full administrative access to protected /webapi routes, including the Doris SQL query API.
