A denial-of-service security issue exists in the affected Logix platforms listed in the table above. The security issue stems from improper validation of input length during CIP message processing. This can result in a major nonrecoverable fault (MNRF), requiring a power cycle to recover
AnalysisAI
Unauthenticated remote denial-of-service in Rockwell Automation CompactLogix 5380 and ControlLogix 5580 industrial controllers allows a network-adjacent attacker to trigger a Major Nonrecoverable Fault (MNRF) by sending a malformed CIP message with an invalid input length, requiring a physical power cycle to restore controller operation. The vulnerability is rooted in CWE-119 (improper buffer bounds restriction) during CIP message processing on EtherNet/IP-accessible PLCs. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the affected PLC's EtherNet/IP interface (TCP/UDP port 44818). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.7 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N) accurately reflects the attack profile: no authentication, no user interaction, and low complexity over the network. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult Rockwell Automation Security Advisory SD1792 (https://www.rockwellautomation.com/en-us/trust-center/security-advisories/advisory.SD1792.html) for vendor-confirmed patch versions and firmware update procedures; no specific fixed firmware version number is available in the current intelligence data, so the exact patched release cannot be cited here. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct a network asset inventory to identify all CompactLogix 5380 and ControlLogix 5580 controllers and assess their network exposure. …
