Executive Summary

CVE-2025-30188 is a vulnerability in the OX App Suite uimiddleware version 2.1.7 where malicious or unintentional API requests can add a large amount of data to caches. This excessive data causes resource exhaustion by evicting critical information needed for the web frontend to operate, leading to denial of service and unavailability of the component. [1]

Impact Analysis

This vulnerability can cause denial of service (DoS) by making the web frontend component unavailable. The cache pollution leads to eviction of essential data, disrupting normal operation and potentially causing downtime or service interruptions. [1]

Detection Guidance

This vulnerability involves malicious or unintentional API requests that add significant data to caches, causing resource exhaustion and denial of service. Detection can involve monitoring for unusually high volumes of API requests or cache usage spikes. Specific commands are not provided in the resources, but general approaches include using network monitoring tools to detect abnormal API traffic patterns and system commands to check cache size and eviction rates. For example, monitoring logs for excessive API calls or using system tools to observe cache memory usage may help detect exploitation attempts. [1]

Mitigation Strategies

The immediate mitigation step is to deploy the provided updates and patch releases. Specifically, upgrade the OX App Suite uimiddleware from version 2.1.7 to version 2.1.8 or later, where the vulnerability is fixed. This will prevent malicious or unintentional API requests from causing cache pollution and denial of service. [1]
