Security Bulletin: IBM App Connect Enterprise Certified Container Dashboard operands that use COS S3 storage are vulnerable to loss of confidentiality [CVE-2024-42459] [CVE-2024-42460] [CVE-2024-42461]

Summary

Node.js Elliptic module is used by IBM App Connect Enterprise Certified Container for encription and signature validation in communication between a Dashboard and COS S3 storage. IBM App Connect Enterprise Certified Container Dashboard operands that use COS S3 storage for storing bar files are vulnerable to loss of confidentiality. This bulletin provides patch information to address the reported vulnerability in the Node.js Elliptic module. [CVE-2024-42459] [CVE-2024-42460] [CVE-2024-42461]

Vulnerability Details

CVEID:CVE-2024-42461
**DESCRIPTION:**Node.js Elliptic module could allow a remote attacker to obtain sensitive information, caused by a flaw with BER-encoded signatures are allowed. By utilizing cryptographic attack techniques, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/350449 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:CVE-2024-42460
**DESCRIPTION:**Node.js Elliptic module could allow a remote attacker to obtain sensitive information, caused by missing check for whether the leading bit of r and s is zero. By utilizing cryptographic attack techniques, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
