A mitigation has been provided for IBM Integration Bus. The latest fix packs for IBM App Connect Enterprise includes async >=3.2.3 and nconf 0.12.0

Vulnerability Details

CVEID: CVE-2021-43138
DESCRIPTION: Async could allow a remote attacker to execute arbitrary code on the system, caused by prototype pollution in the mapValues() method. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/223605 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID: CVE-2022-21803
DESCRIPTION: Node.js nconf module could allow a remote attacker to execute arbitrary code on the system, caused by a prototype pollution flaw when using the memory engine. By adding or modifying properties of Object.prototype using a __proto__ or constructor payload, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 7.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/224357 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)
