CVE-2022-23307: A deserialization flaw in the Chainsaw component of Log4j 1 can lead to malicious code execution.

Published Jan 18, 2022
·
Updated

A deserialization flaw was found in Apache log4j 1.2.x. While reading serialized log events, they are improperly deserialized.

Note this is the same as CVE-2020-9493 which identified a deserialization issue in Apache Chainsaw. Prior to Chainsaw V2.0, Chainsaw was a component of Apache Log4j 1.2.x.

Other sources

A flaw was found in the log4j 1.x chainsaw component, where the contents of certain log entries are deserialized and possibly permit code execution. This flaw allows an attacker to send a malicious request with serialized data to the server to be deserialized when the chainsaw component is run.

Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by an unsafe deserialization in the in Apache Chainsaw component. By sending specially-crafted input, an attacker could exploit this vulnerability to execute arbitrary code on the system.

CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. Prior to Chainsaw V2.0 Chainsaw was a component of Apache Log4j 1.2.x where the same issue exists.
