Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-23539)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to insecure key types are used for signature verification. A remote user can enable legacy keys usage.


2) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-23541)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to insecure implementation of key retrieval function. A remote user attacker can cause successful validation of forged tokens.


3) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-23540)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to insecure default algorithm in jwt.verify(). A remote attacker can cause signature validation bypass.


4) Input validation error (CVE-ID: CVE-2022-23529)

The vulnerability allows a remote attacker to execute arbitrary code on the system.

The vulnerability exists due to insufficient validation of user-supplied input in jwt.verify function. A remote attacker can pass specially crafted input to the application and execute arbitrary code on the target system.
