Summary

There are three vulnerabilities in Nimbus JOSE+JWT 3.1.2 used by IBM Spectrum Conductor 2.4.1, IBM Spectrum Conductor 2.4.0 and IBM Spectrum Conductor 2.3.0. IBM Spectrum Conductor 2.4.1, IBM Spectrum Conductor 2.4.0 and IBM Spectrum Conductor 2.3 have addressed the applicable CVEs.

Vulnerability Details

CVEID:CVE-2017-12974
**DESCRIPTION:**Connect2id Nimbus JOSE+JWT could provide weaker than expected security, caused by proceeding with ECKey construction without ensuring that the public x and y coordinates are on the specified curve. A remote attacker could exploit this vulnerability to conduct an Invalid Curve Attack.
CVSS Base score: 7.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/130788 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID:CVE-2017-12972
**DESCRIPTION:**Connect2id Nimbus JOSE+JWT could provide weaker than expected security, caused by the lack of integer-overflow check when converting length values from bytes to bits. A remote attacker could exploit this vulnerability to conduct a HMAC bypass attack.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/130790 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:CVE-2017-16007
**DESCRIPTION:**Node.js node-jose module could allow a remote attacker to obtain sensitive information, caused by a flaw when JWE with Key Agreement with Elliptic Curve Diffie-Hellman Ephemeral Static (ECDH-ES) is used. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to recover the private secret key.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/148284 for the current score.
