CVE-2022-30310 Festo CVE debrief

Who should care

Industrial control system operators, OT security teams, plant engineers, and integrators responsible for Festo Controller CECC-X-M1 and related Servo Press Kit YJKP deployments should treat this as high priority. It is especially important for environments where the device web interface or management plane is reachable from broader networks.

Technical summary

The flaw affects Festo Controller CECC-X-M1 product family variants and related Servo Press Kit YJKP installations. The advisory states that the HTTP endpoint "cecc-x-acknerr-request" in a POST request does not check port syntax, creating a command-injection condition with improper access control. The result can be execution of system commands with root privileges. CISA's CSAF advisory lists affected firmware/product combinations and identifies fixed releases including 3.8.18 and 4.0.18 depending on the specific product/order code.

Defensive priority

Critical and urgent. Because the issue is network-reachable, requires no user interaction, and can lead to root-level command execution, organizations should prioritize inventorying exposed assets, confirming firmware versions, and applying the vendor-fixed release as soon as operationally feasible.

Recommended defensive actions

• Inventory all Festo CECC-X-M1 and Servo Press Kit YJKP assets and confirm the exact firmware and order code in use.
• Upgrade each affected product to the fixed firmware version listed in the advisory for that specific model, using 3.8.18 or 4.0.18 as applicable.
• Restrict access to the device HTTP management interface so only trusted administrative networks can reach it.
• Review network and device logs for unexpected or unauthorized POST requests to the "cecc-x-acknerr-request" endpoint.
• Apply ICS defense-in-depth guidance and segment OT devices from user and enterprise networks where possible.

Evidence notes

The supplied CISA CSAF source and linked vendor references describe a POST-based HTTP endpoint validation failure that can lead to command injection and root-privileged system command execution. The source lists affected Festo products and remediation versions, including 3.8.18 and 4.0.18 for specific CECC-X-M1 variants. The CVSS vector provided is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, which aligns with a remotely exploitable, high-impact issue. The supplied enrichment does not indicate KEV inclusion.
