CVE-2026-25787
CriticalCVSS 9.1Exploitation Probability (EPSS)
Low risk29th percentile - higher than 29% of all known CVEs
Summary
The vulnerability in industrial devices is due to improper validation and sanitization of the Technology Object (TO) name displayed on the 'Motion Control Diagnostics' page of the web interface. This allows an authenticated attacker authorized to download a TIA project into the device to inject malicious scripts into the page.
Risk Assessment
The risk involves execution of malicious code within the web session of a privileged user who visits the motion diagnostics page. This could lead to session hijacking, configuration changes, or further privilege escalation within the control system.
Recommendation
Immediately update the device firmware to a version containing the fix for this vulnerability. Until the update is applied, restrict web interface access to trusted users and networks only.
Original NVD description (English source)
Affected devices do not properly validate and sanitize Technology Object (TO) name rendered on the "Motion Control Diagnostics" page of the web interface. This could allow an authenticated attacker who is authorized to download a TIA project into the product, to inject malicious scripts into the page. If a benign user with appropriate rights accesses the "Motion Control Diagnostics" parameters page, the malicious code would be executed in the scope of their web session.
