CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. This Deserialization of Untrusted Data vulnerability could allow attackers to execute arbitrary code through malicious serialized objects.
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. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This SQL Injection vulnerability could allow attackers to execute arbitrary SQL commands against the database.
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. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity.
Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. Rated low severity (CVSS 3.7), this vulnerability is remotely exploitable, no authentication required.
