Tycon Systems TPDIN-Monitor-WEB3 versions 2.2.9 and prior are vulnerable to a cross-site request forgery vulnerability. This could allow an attacker to perform state changing operations on the device.
AnalysisAI
Cross-site request forgery in Tycon Systems TPDIN-Monitor-WEB3 versions 2.2.9 and prior allows a remote unauthenticated attacker to perform unauthorized state-changing operations on an industrial DC power monitoring device by tricking an authenticated administrator into visiting a malicious webpage. Reported via CISA ICS-CERT advisory ICSA-26-246-08, the vulnerability is rooted in a missing anti-CSRF mechanism in the device web interface; a firmware upgrade to v2.4.2 is available. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a device administrator maintain an active authenticated session with the TPDIN-Monitor-WEB3 web interface while simultaneously visiting an attacker-controlled webpage. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.6 reflects the high impact potential (VC:H/VI:H/VA:H) of unauthorized configuration or control operations on a power monitoring device, but the UI:A requirement is the decisive constraint - the attack cannot proceed without a currently authenticated administrator actively visiting an attacker-controlled resource. … 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 | Upgrade TPDIN-Monitor-WEB3 firmware to version 2.4.2 using the images published by Tycon Systems and referenced in CISA ICS advisory ICSA-26-246-08 (https://www.cisa.gov/news-events/ics-advisories/icsa-26-246-08). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct a complete inventory of all TPDIN-Monitor-WEB3 devices currently deployed and identify which are running firmware version 2.2.9 or earlier, prioritizing systems that support production power distribution. …
