Summary
It was discovered that the SocketServer component of Apache Log4j 1.2
incorrectly handled deserialization. An attacker could possibly use this issue
to execute arbitrary code. This issue only affected Ubuntu 16.04 ESM.
(CVE-2019-17571)
It was discovered that the JMSSink component of Apache Log4j 1.2 incorrectly
handled deserialization. An attacker could possibly use this issue to execute
arbitrary code. (CVE-2022-23302)
It was discovered that Apache Log4j 1.2 incorrectly handled certain SQL
statements. A remote attacker could possibly use this issue to perform an SQL
injection attack and alter the database. This issue was only fixed in Ubuntu
18.04 LTS and Ubuntu 20.04 LTS. (CVE-2022-23305)
It was discovered that the Chainsaw component of Apache Log4j 1.2 incorrectly
handled deserialization. An attacker could possibly use this issue to execute
arbitrary code. This issue was only fixed in Ubuntu 18.04 LTS and Ubuntu 20.04
LTS. (CVE-2022-23307)

Critical 9.8
Deserialization of Untrusted Data in Log4j
Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log dat…

Critical 9.8
SQL injection in JDBC Appender in Apache Log4j V1
By design, the JDBCAppender in Log4j 1.2.x accepts an SQL statement as a configuration parameter where the values to be inserted are converters from PatternLayout. The message converter, %m, is likely to always be included. This allows attackers to manipulate…

Deserialization of untrusted data in JMSSink in Apache Log4j 1.x
JMSSink in all versions of Log4j 1.x is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration or if the configuration references an LDAP service the attacker has access to. The attacker can provide a Top…
