Local IOCTL from an authenticated low-priv user (AV:L/PR:L); unreliable/groomed kernel write gives AC:H; kernel EoP yields full C/I/A on the host with no scope change (S:U).

Lifecycle Timeline
3DescriptionCVE.org
An out-of-bounds write vulnerability in the Productivity Suite allows a local attacker to trigger kernel memory corruption via a crafted IOCTL request, potentially resulting in privilege escalation or system instability.
AnalysisAI
Local privilege escalation in AutomationDirect Productivity Suite lets an authenticated local attacker corrupt kernel memory by issuing a crafted IOCTL request to an out-of-bounds write flaw (CWE-787). Successful exploitation can elevate privileges to SYSTEM/kernel level or crash the host running this engineering workstation software for AutomationDirect Productivity-series PLCs. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access with an already-authenticated low-privileged session (CVSS PR:L, AV:L) on a Windows host that has AutomationDirect Productivity Suite installed, plus the ability to open and send IOCTL requests to its kernel driver - there is no remote or network path and no user interaction by a victim is needed (UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:L/AC:H/AT:N/PR:L/UI:N, base 7.3) frames this as a locally-exploitable, high-complexity, low-privilege issue with high confidentiality, integrity and availability impact to the vulnerable system but no scope change to other systems - consistent with a driver-level EoP rather than a remotely wormable flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has already obtained a low-privileged interactive session on an engineering workstation (via phishing, stolen operator credentials, or an insider) runs a small user-mode program that opens the Productivity Suite driver and sends a crafted IOCTL with malformed size/offset fields. The out-of-bounds kernel write is groomed to overwrite a kernel structure, escalating the process to SYSTEM and giving the attacker full control of the OT engineering host; a botched attempt instead bugchecks the machine. … |
| Remediation | Patch available per vendor advisory: download and install the fixed Productivity Suite release from AutomationDirect's software downloads portal (https://www.automationdirect.com/support/software-downloads) and follow the guidance in CISA advisory ICSA-26-197-04 (https://www.cisa.gov/news-events/ics-advisories/icsa-26-197-04); an exact fixed version number was not provided in the source data, so confirm the target build against the advisory before deployment. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: conduct inventory of all systems running AutomationDirect Productivity Suite and document their criticality to operations; immediately restrict local logon access to these workstations to authorized engineering personnel only. …
