Description

This security bulletin contains information about 4 vulnerabilities.


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

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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.


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

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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.


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

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber


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.


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

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber


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.
