Security Bulletin: Vulnerabilities in Apache Log4j affects IBm Edge Application Manager (CVE-2021-45105 and CVE-2021-45046)

Security Bulletin


Summary

IBM Edge Application Manager (IEAM) 4.3.1 contains two dependencies that are affected by the Apache Log4j vulnerabilities described in CVE-2021-45105 and CVE-2021-45046. Note that IBM Edge Application Manager does not use Log4j directly. The first relates to code included in Intel Secure Device Onboarding (SDO) which is open-source code that IEAM uses to help with onboarding devices into an IEAM cluster. The other is a dependency on IBM Cloud Pak Foundational Services (IBM Common Services) which includes an unused Operator that contains a vulnerable version of Log4j. This bulletin provides a remediation for both vulnerabilities, CVE-2021-45105 and CVE-2021-45046, by upgrading IBM Edge Application Manager to the latest version. This includes updates to Log4j to version 2.17 which addresses any potential exposure to the Log4j vulnerabilities.

Vulnerability Details

CVEID:   CVE-2021-45105
DESCRIPTION:   Apache Log4j is vulnerable to a denial of service, caused by the failure to protect from uncontrolled recursion from self-referential lookups. A remote attacker with control over Thread Context Map (MDC) input data could craft malicious input data that contains a recursive lookup to cause a StackOverflowError that will terminate the process. Note: The vulnerability is also called LOG4J2-3230.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/215647 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:   CVE-2021-45046
DESCRIPTION:   Apache Log4j could result in remote code execution, caused by an incomplete fix of CVE-2021-44228 in certain non-default configurations. When the logging configuration uses a non-default Pattern Layout with a Context Lookup, an attacker with control over Thread Context Map (MDC) input data can craft malicious input data using a JNDI Lookup pattern to leak sensitive information and remote code execution in some environments and local code execution in all environments.
CVSS Base score: 9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/215195 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H)
