Security Bulletin: IBM App Connect Enterprise and IBM Integration Bus are vulnerable to a remote attacker due to Node.js (CVE-2022-43548 & CVE-2022-35256)

Summary

IBM App Connect Enterprise and IBM Integration Bus are vulnerable to a remote attacker due to Node.js (CVE-2022-43548 & CVE-2022-35256). The fix includes Node.js 14.21.1

Vulnerability Details

CVEID:CVE-2022-43548
**DESCRIPTION:**Node.js could allow a remote attacker to execute arbitrary code on the system. The rebinding protector for --inspect still allows invalid IP address, specifically, the octal format. By combining with an active --inspect session, an attacker could exploit this vulnerability to perform DNS rebinding and execute arbitrary code on the system.
CVSS Base score: 5.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/241552 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID:CVE-2022-35256
**DESCRIPTION:**Node.js is vulnerable to HTTP request smuggling, caused by the failure to correctly handle header fields that are not terminated with CLRF by the llhttp parser in the http module. A remote attacker could send a specially-crafted request to lead to HTTP Request Smuggling (HRS). An attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/236964 for the current score.
