A flaw was found in the Apache Log4j logging library 2.x. when the logging configuration uses a non-default Pattern Layout with a Context Lookup. Attackers with control over Thread Context Map (MDC) input data can craft malicious input data that contains a recursive lookup and can cause Denial of Service.
A flaw was found in jackson-databind 2.x. FasterXML jackson-databind 2.x mishandles the interaction between serialization gadgets and typing. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
A flaw was found in jackson-databind 2.x. FasterXML jackson-databind 2.x mishandles the interaction between serialization gadgets and typing. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
A flaw was found in jackson-databind 2.x in versions prior to 2.9.10.4. FasterXML jackson-databind 2.x mishandles the interaction between serialization gadgets and typing. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
A flaw was found in camel. Apache Camel RabbitMQ enables java deserialization, by default, without any means of disabling which can lead to arbitrary code being executed. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
A flaw was found in dom4j library. By using the default SaxReader() provided by Dom4J, external DTDs and External Entities are allowed, resulting in a possible XXE.
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.

A flaw was found in the Java logging library Apache Log4j in version 1.x. JDBCAppender in Log4j 1.x is vulnerable to SQL injection in untrusted data. This allows a remote attacker to run SQL statements in the database if the deployed application is configured to use JDBCAppender with certain interpolation tokens.
FasterXML jackson-databind 2.x before 2.6.7.4, 2.7.x before 2.7.9.7, 2.8.x before 2.8.11.5, and 2.9.x before 2.9.10.2 lacks certain net.sf.ehcache blocking.
