CVE-2024-22025 NodeJS CVE debrief
CVE-2024-22025 is a denial-of-service vulnerability in Node.js affecting Siemens SINEC INS, published 2024-11-12. The vulnerability stems from resource exhaustion during fetch() brotli decoding, where a remote attacker can send a specially crafted request to trigger a DoS condition. The CVSS 3.1 score of 5.3 (MEDIUM) reflects network accessibility with low attack complexity, no required privileges or user interaction, and low availability impact. Siemens has released a vendor fix: update to V1.0 SP2 Update 3 or later. CISA published this advisory as ICSA-24-319-08, cross-referencing Siemens' security advisory SSA-915275.

Who should care
Organizations operating Siemens SINEC INS in industrial environments, OT security teams managing Node.js-based applications, and infrastructure operators relying on fetch() for HTTP communications should prioritize this update.
Technical summary
The vulnerability exists in Node.js's implementation of the fetch() API when handling Brotli-compressed responses. Insufficient resource limits during decompression allow an attacker to exhaust system resources through crafted compressed data, resulting in denial of service. The attack vector is network-based with no authentication required.
Defensive priority
medium
Recommended defensive actions
- Update Siemens SINEC INS to V1.0 SP2 Update 3 or later version per vendor guidance.
- Review network segmentation for SINEC INS deployments to limit exposure of affected systems.
- Monitor for anomalous request patterns that may indicate attempted exploitation of fetch() brotli decoding.
- Apply CISA ICS recommended practices for defense-in-depth strategies in industrial control environments.
