CVE intelligence and bounded remediation
CVE-2016-9498 — ManageEngine Applications Manager 12 and 13 before build 13200, allows unserialization of unsafe Java objects
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 Manager's RMI registry is running with privileges of system administrator, by exploiting this vulnerability an attacker gains highest privileges on the underlying operating system.

Unsafe deserialization and object reconstruction
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Inventory serialization formats accepted from requests, queues, caches, files, cookies, and cross-service messages.
- Trace whether untrusted input can select classes, types, callbacks, constructors, or object hooks during decoding.
- Identify signing, schema validation, trust-boundary, and compatibility settings for each decoder.
Remediate safely
- Replace native object deserialization with a data-only format and explicit schema validation.
- If replacement is not immediate, use a safe decoder with a minimal type allowlist and disable polymorphic or executable hooks.
- Update the affected library and add inert tests for unknown types, extra fields, malformed nesting, and unsigned data.
