CyberRota Analysis

AI-Generated

Eclipse Milo versions 1.0.0 through 1.1.4 are vulnerable due to a lack of exception safety in monitored-item quota accounting, which can lead to a `StackOverflowError` when processing deeply nested PubSub ExtensionObjects. This flaw allows an unauthenticated remote client to exhaust the server's global monitored-item quota, effectively blocking all new monitored item creations until the server is restarted. Organizations using affected versions should prioritize remediation to prevent potential denial-of-service conditions in their systems.

Original NVD Description

In Eclipse Milo versions 1.0.0 through 1.1.4, monitored-item quota accounting is not exception-safe: if item creation fails with an unchecked error, the server-global reservation is not restored. Deeply nested PubSub ExtensionObjects in a `CreateMonitoredItems` event filter can trigger a `StackOverflowError` during decoding, allowing an unauthenticated remote client to exhaust a finite global monitored-item quota and prevent all clients from creating new monitored items until restart. Existing monitored items and other server functions remain unaffected.
