This is done by writing beyond the designated memory area, which causes an access violation. Once inside, the threat actor can run harmful code on the system. This affects the confidentiality, integrity, and availability of the product. To trigger this, the user would unwittingly need to open a malicious file shared by the threat actor.\n\n","published_at":"2024-03-26T15:34:35.837000Z","last_modified_at":null,"cvss_v3_score":7.8,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-787"],"nvd_references":["https://www.rockwellautomation.com/en-us/support/advisory.SD-1665.html"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:52:30.567529Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"rockwell-automation","vendor_name":"Rockwell Automation","product_slug":"arena-simulation","product_name":"Arena® Simulation","version_start":"Version 16.00 - 16.20.02","version_start_inclusive":true,"version_end":"Version 16.00 - 16.20.02","version_end_inclusive":true,"cpe23_uri":"cve5:rockwell-automation:arena-simulation:Version 16.00 - 16.20.02:Version 16.00 - 16.20.02"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.rockwellautomation.com/en-us/support/advisory.SD-1665.html","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2024-03-26T15:34:35.837000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:34:01.064052Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:34:01.064052Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:34:01.064052Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:52:30.567529Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:52:30.567529Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:52:30.567529Z","label":"SSVC decision revised","source":"vulnrichment"}]}
