CVE-2026-125298

Summary

The AsiaInfo BSS 9.2.0–9.2.40 fails to properly validate cryptographic signatures on JWTs, allowing attackers to forge valid-looking tokens without knowing the signing key. This enables unauthenticated remote users to impersonate privileged accounts and execute unauthorized administrative actions.

Exploitability

Exploitation is trivial for a remote, unauthenticated attacker due to the lack of signature verification; no prior access or user interaction is required.

Blast radius

Successful exploitation could lead to full system compromise including data exfiltration, unauthorized configuration changes, and service disruption across the business support system.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to AsiaInfo BSS version 9.2.41 or later, which includes the fix for CVE-2026-125298.
