CVE-2016-9498

ManageEngine Applications Manager 12 and 13 before build 13200, allows unserialization of unsafe Java objects. The vulnerability can be exploited by remote user without authentication and it allows to execute remote code compromising the application as well as the operating system. As Application Managers RMI registry is running with privileges of system administrator, by exploiting this vulnerability an attacker gains highest privileges on the underlying operating system.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Potential Mitigations

• Make fields transient to protect them from deserialization.
• An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
