jackson-databind: default typing mishandling leading to remote code execution

A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the ehcache and logback JNDI gadgets when used in conjunction with polymorphic type handling methods such as enableDefaultTyping or when @JsonTypeInfo is using Id.CLAS...

jackson-databind: failure to block the logback-core class from polymorphic deserialization leading to remote code execution

A flaw was discovered in FasterXML jackson-databind in versions prior to 2.9.9. The vulnerability would permit polymorphic deserialization of malicious objects using the logback-core gadget when used in conjunction with polymorphic type handling methods such as enableDefaultTyping or when...

The vulnerability of the FasterXML function in the Jackson-Databind Java library for JSON file grammar analysis allows attackers to compromise data integrity, gain access to confidential information, and cause service failures.

The vulnerability of the FasterXML function in the Jackson-Databind Java library for JSON file grammar analysis is related to the blocking of the polymorphic deserialization in the jboss-common-core class. Exploiting this vulnerability could allow an attacker to compromise data integrity, gain...

Debian DLA-1879-1 : jackson-databind security update

Deserialization flaws were discovered in jackson-databind relating to EHCache and logback/jndi, which could allow an unauthenticated user to perform remote code execution. The issue was resolved by extending the blacklist and blocking more classes from polymorphic deserialization. For Debian 8...
