CVE-2019-14439 – jackson-databind: Polymorphic typing issue related to logback/JNDI
https://notcve.org/view.php?id=CVE-2019-14439
A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x before 2.9.9.2. This occurs when Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint and the service has the logback jar in the classpath. Se detectó un problema de escritura polimórfica en jackson-databind de FasterXML versiones 2.x anteriores a 2.9.9.2. Esto ocurre cuando la Escritura Predeterminada está habilitada (globalmente o para una propiedad específica) para un endpoint JSON expuesto externamente y el servicio tiene el jar de logback en el classpath. • https://github.com/jas502n/CVE-2019-14439 https://access.redhat.com/errata/RHSA-2019:3200 https://github.com/FasterXML/jackson-databind/commit/ad418eeb974e357f2797aef64aa0e3ffaaa6125b https://github.com/FasterXML/jackson-databind/compare/jackson-databind-2.9.9.1...jackson-databind-2.9.9.2 https://github.com/FasterXML/jackson-databind/issues/2389 https://lists.apache.org/thread.html/0d4b630d9ee724aee50703397d9d1afa2b2befc9395ba7797d0ccea9%40%3Cdev.tomee.apache.org%3E https://lists.apache.org/thread.html/2d2a76440becb610b9 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-502: Deserialization of Untrusted Data •
CVE-2019-14379 – jackson-databind: default typing mishandling leading to remote code execution
https://notcve.org/view.php?id=CVE-2019-14379
SubTypeValidator.java in FasterXML jackson-databind before 2.9.9.2 mishandles default typing when ehcache is used (because of net.sf.ehcache.transaction.manager.DefaultTransactionManagerLookup), leading to remote code execution. El archivo SubTypeValidator.java en jackson-databind de FasterXML en versiones anteriores a la 2.9.9.2 maneja inapropiadamente la escritura predeterminada cuando se usa ehcache (debido a net.sf.ehcache.transaction.manager.DefaultTransactionManagerLookup), lo que conlleva a la ejecución de código remoto. 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.CLASS` or `Id.MINIMAL_CLASS` or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code. • http://seclists.org/fulldisclosure/2022/Mar/23 https://access.redhat.com/errata/RHBA-2019:2824 https://access.redhat.com/errata/RHSA-2019:2743 https://access.redhat.com/errata/RHSA-2019:2858 https://access.redhat.com/errata/RHSA-2019:2935 https://access.redhat.com/errata/RHSA-2019:2936 https://access.redhat.com/errata/RHSA-2019:2937 https://access.redhat.com/errata/RHSA-2019:2938 https://access.redhat.com/errata/RHSA-2019:2998 https://access.redhat.com/errata/RHSA-2 • CWE-502: Deserialization of Untrusted Data CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •
