Summary

There are multiple vulnerabilities in JSON Web Token implementation used by IBM Decision Optimization in IBM Cloud Pak for Data. IBM Decision Optimization in IBM Cloud Pak for Data has addressed the applicable CVEs.

Vulnerability Details

CVEID:CVE-2022-23541
**DESCRIPTION:**Auth0 jsonwebtoken could allow a remote authenticated attacker to bypass security restrictions, caused by an insecure implementation of key retrieval function. By sending a specially-crafted request, an attacker could exploit this vulnerability to forge Public/Private Tokens from RSA to HMAC.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/242966 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L)

CVEID:CVE-2022-23539
**DESCRIPTION:**Auth0 jsonwebtoken could provide weaker than expected security, caused by an unrestricted key type issue. A remote authenticated attacker could exploit this vulnerability to allow legacy keys usage and launch further attacks on the system.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/242968 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:N)

CVEID:CVE-2022-23529
**DESCRIPTION:**Auth0 jsonwebtoken could allow a remote authenticated attacker to execute arbitrary code on the system, caused by improper input validation by the jwt.verify function. By sending a specially-crafted request using the key retrieval parameter, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/242967 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2022-23540
**DESCRIPTION:**Auth0 jsonwebtoken could allow a remote authenticated attacker to bypass security restrictions, caused by an insecure default algorithm flaw in the jwt.verify() function. By sending a specially-crafted request, an attacker could exploit this vulnerability to bypass signature validation.
CVSS Base score: 6.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/242969 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:L)
