FasterXML jackson-databind through 2.8.10 and 2.9.x through 2.9.3 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 Spring libraries are available in the classpath. FasterXML jackson-databind hasta la versión 2.8.10 y 2.9.x hasta la 2.9.3 permite que se ejecute código de manera remota y no autenticada debido a una solución incompleta de la vulnerabilidad de deserialización CVE-2017-7525. Esto es explotable enviando una entrada JSON manipulada maliciosamente al método readValue de ObjectMapper, omitiendo una lista negra que no es efectiva si las librerías Spring están disponibles en el classpath.

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.

Remote code execution occurs in Apache Solr before 7.1 with Apache Lucene before 7.1 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. Elasticsearch, although it uses Lucene, is NOT vulnerable to this. Note that the XML external entity expansion vulnerability occurs in the XML Query Parser which is available, by default, for any query request with parameters deftype=xmlparser and can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server. Note also that the second vulnerability relates to remote code execution using the RunExecutableListener available on all affected versions of Solr. Ocurre una ejecución remota de código en Apache Solr en versiones anteriores a la 7.1 con Apache Lucene en versiones anteriores a la 7.1 explotando XXE junto con el uso de un comando add-listener de la API de configuración para alcanzar la clase RunExecutableListener. • https://www.exploit-db.com/exploits/43009 http://mail-archives.us.apache.org/mod_mbox/www-announce/201710.mbox/%3CCAOOKt51UO_6Vy%3Dj8W%3Dx1pMbLW9VJfZyFWz7pAnXJC_OAdSZubA%40mail.gmail.com%3E http://openwall.com/lists/oss-security/2017/10/13/1 http://www.securityfocus.com/bid/101261 https://access.redhat.com/errata/RHSA-2017:3123 https://access.redhat.com/errata/RHSA-2017:3124 https://access.redhat.com/errata/RHSA-2017:3244 https://access.redhat.com/errata/RHSA-2017:3451 https:/ • CWE-138: Improper Neutralization of Special Elements CWE-611: Improper Restriction of XML External Entity Reference •
