Security Bulletin: Hortonworks DataFlow product has log messages vulnerable to arbitrary code execution, denial of service, and remote code execution due to Apache Log4j vulnerabilities [CVE-2021-44228], [CVE-2021-45105], and [CVE-2021-45046]

Summary

Hortonworks DataFlow product for IBM has log messages vulnerable to arbitrary code execution, denial of service, and remote code execution due to Apache Log4j vulnerabilities [CVE-2021-44228], [CVE-2021-45105], and [CVE-2021-45046].

Vulnerability Details

CVEID:CVE-2021-44228
**DESCRIPTION:**Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by the failure to protect against attacker controlled LDAP and other JNDI related endpoints by JNDI features. By sending a specially crafted code string, an attacker could exploit this vulnerability to load arbitrary Java code on the server and take complete control of the system. Note: The vulnerability is also called Log4Shell or LogJam.
CVSS Base score: 10
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/214921 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H)

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.
