OpenNMS Horizon RCE via Unsafe Deserialization
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | org.opennms.core:org.opennms.core.daemon | < 26.0.1 | 26.0.1 |
Details
As written in the advisory (Markdown source, shown as plain text).
An issue was discovered in OpenNMS Horizon before 26.0.1, and Meridian before 2018.1.19 and 2019 before 2019.1.7. The ActiveMQ channel configuration allowed for arbitrary deserialization of Java objects (aka ActiveMQ Minion payload deserialization), leading to remote code execution for any authenticated channel user regardless of its assigned permissions.
