  1. Flaws in Java AMF Libraries Allow Remote Code Execution

Deserialization-related vulnerabilities found in several Java implementations of AMF3 can be exploited for unauthenticated remote code execution and XXE attacks, warned CERT/CC. The security holes were reported to CERT/CC and vendors by Markus Wulftange, the senior penetration tester at Code White. Patches have been made available for some of the affected products. Serialization is the process where an object is converted to a stream of bytes in order to store or transmit that object to memory or a file. The process in which serialized data is extracted is called deserialization and it can lead to significant security flaws if not handled properly. The flaws allow an attacker to execute code remotely. This security hole is said to affect Atlassian’s JIRA, Exadel’s Flamingo, GraniteDS, Spring spring-flex, and WebORB for Java by Midnight Coders. According to CERT/CC, products from HPE, SonicWall and VMware could also be affected according to report published by SecurityWeek.

Cyber Security Tips: Developers are recommended to use versions of JDK that implement serialization blacklisting filters and ensure that their products properly handle deserialized data from untrusted sources.
