CVE-2024-45825
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCVE-2024-45825 IMPACT A denial-of-service vulnerability exists in the affected products. The vulnerability occurs when a malformed CIP packet is sent over the network to the device and results in a major nonrecoverable fault causing a denial-of-service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is a denial-of-service vulnerability in industrial control devices that process CIP (Common Industrial Protocol) packets. When a malformed CIP packet is sent to the affected device, it triggers a major nonrecoverable fault, causing the device to become unavailable. The attack is network-based and does not require authentication.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device modelCheck the device nameplate, product documentation, or access the device's web interface/management console to confirm the model is Rockwell Automation 5015 U8ihftAffected if Device is not a 5015 U8ihft model, then not affected by this specific CVE
-
Check firmware versionAccess the device's web interface, management console, or use vendor tools to retrieve the installed firmware version. Compare against 1.011 and 1.012Affected if Firmware version is exactly 1.011 or 1.012, then device is vulnerable
-
Verify CIP protocol is enabledCheck device network settings or configuration menu for CIP (Common Industrial Protocol) communication settings. This is typically found under Protocol Configuration, Network Settings, or I/O ConfigurationAffected if CIP protocol is disabled, the malformed packet trigger may not be reachable even on vulnerable firmware versions
-
Assess network exposure of CIP portScan the network for open CIP ports (typically UDP/TCP port 2222 or 44818). Check firewall rules and network segmentation to determine if untrusted network traffic can reach the deviceAffected if Device has CIP port exposed to untrusted/unauthenticated network segments, the attack surface is present
A user is affected if they have a 5015 U8ihft device running firmware 1.011 or 1.012 with CIP protocol enabled and accessible from a network where attackers can send malformed CIP packets.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied patches or firmware updates that address CIP packet validation. Implement network segmentation and firewall rules to restrict untrusted traffic from reaching affected devices until patches can be applied.
