Vulnerability Details

CVEID:CVE-2022-33915
**DESCRIPTION:**Amazon AWS Apache Log4j hotpatch package could allow a local authenticated attacker to gain elevated privileges on the system, caused by a race condition. By running a custom java process that performs exec() of an SUID binary, an authenticated attacker could exploit this vulnerability to execute a arbitrary code with elevated privileges.
CVSS Base score: 7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/229133 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2021-4104
**DESCRIPTION:**Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by the deserialization of untrusted data when the attacker has write access to the Log4j configuration. If the deployed application is configured to use JMSAppender, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/215048 for the current score.

CVEID:CVE-2021-44832
**DESCRIPTION:**Apache Log4j could allow a remote attacker with permission to modify the logging configuration file to execute arbitrary code on the system. By constructing a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI , an attacker could exploit this vulnerability to execute remote code.
CVSS Base score: 6.6
