Security Bulletin: StoredIQ is vulnerable to denial of service and remote code execution in Apache Log4j (CVE-2021-44228, CVE-2021-45046).

Summary

StoredIQ is vulnerable to denial of service and remote code execution in Apache Log4j (CVE-2021-44228, CVE-2021-45046). Apache Log4j is used by StoredIQ as part of its logging infrastructure. The fix includes Apache Log4j v2.17.1.

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
