FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to execute arbitrary code by leveraging failure to block the blaze-ds-opt and blaze-ds-core classes from polymorphic deserialization. Las versiones 2.x de FasterXML jackson-databind anteriores a la 2.9.7 podrían permitir a los atacantes remotos ejecutar código arbitrario aprovechando un fallo para bloquear las clases blaze-ds-opt y blaze-ds-core de deserialización polimórfica. A flaw was discovered in jackson-databind, where it would permit polymorphic deserialization of a malicious object using blaze classes. An attacker could use this flaw to execute arbitrary code. • https://access.redhat.com/errata/RHBA-2019:0959 https://access.redhat.com/errata/RHSA-2019:0782 https://access.redhat.com/errata/RHSA-2019:0877 https://access.redhat.com/errata/RHSA-2019:1782 https://access.redhat.com/errata/RHSA-2019:1797 https://access.redhat.com/errata/RHSA-2019:1822 https://access.redhat.com/errata/RHSA-2019:1823 https://access.redhat.com/errata/RHSA-2019:2804 https://access.redhat.com/errata/RHSA-2019:2858 https://access.redhat.com/errata/RHSA • CWE-502: Deserialization of Untrusted Data •

FasterXML jackson-databind before 2.7.9.3, 2.8.x before 2.8.11.1 and 2.9.x before 2.9.5 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 deserialization flaw. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a blacklist that is ineffective if the c3p0 libraries are available in the classpath. FasterXML jackson-databind, en versiones anteriores a la 2.7.9.3, versiones 2.8.x anteriores a la 2.8.11.1 y las versiones 2.9.x anteriores a la 2.9.5, permite la ejecución remota de código sin autenticar debido a una solución incompleta para el error de deserialización CVE-2017-7525. Esto puede explotarse mediante el envío de entradas JSON maliciosamente manipuladas al método readValue de ObjectMapper, omitiendo una lista negra no efectiva si las librerías c3p0 están disponibles en la classpath. • https://github.com/tafamace/CVE-2018-7489 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/103203 http://www.securitytracker.com/id/1040693 http://www.securitytracker.com/id/1041890 https://access.redhat.com/errata/RHSA-2018:1447 https://access.redhat.com/errata/RHSA-2018:1448 https:/ • CWE-20: Improper Input Validation CWE-184: Incomplete List of Disallowed Inputs CWE-502: Deserialization of Untrusted Data •

A deserialization flaw was discovered in the jackson-databind in versions before 2.8.10 and 2.9.1, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. This issue extends the previous flaw CVE-2017-7525 by blacklisting more classes that could be used maliciously. Se ha descubierto un error de deserialización en jackson-databind, en versiones anteriores a la 2.8.10 y a la 2.9.1, que podría permitir que un usuario no autenticado ejecute código enviando las entradas maliciosamente manipuladas al método readValue de ObjectMapper. Este problema amplía el error previo de CVE-2017-7525 metiendo en la lista negra más clases que podrían emplearse de forma maliciosa.
