Security Bulletin: IBM Analytic Accelerator Framework for Communication Service Providers & IBM Customer and Network Analytics for Communications Service Providers and Datasets Impacted by Log4j Vulnerabilities (CVE-2021-45046, CVE-2021-45105)

Summary

Apache Log4j is used by as part of its logging infrastructure by IBM Analytic Accelerator Framework for Communication Service Providers (AAF) and IBM Customer and Network Analytics for Communications Service Providers and Datasets (CNA). These products are vulnerable to CVE-2021-45105 and CVE-2021-45046. The fix includes includes Apache Log4j v2.17.0

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
