CVE-2026-107640 Integrics CVE debrief

Who should care

System administrators and security teams responsible for Integrics Enswitch systems should assess exposure and prioritize patching. Roles include IT administrators, security engineers, and compliance officers. Deployment contexts include environments where Integrics Enswitch is used for critical infrastructure, customer-facing services, or sensitive data processing.

Why it matters

CVE-2026-107640 is a critical authentication bypass vulnerability in Integrics Enswitch versions 3.13 through 4.4. It allows unauthenticated attackers to change account passwords via the Password Reset API. This vulnerability requires immediate attention from system administrators and security teams to prevent potential account takeovers and system compromise.

• Unauthenticated password changes can lead to account takeovers
• Administrator account takeovers can result in elevated privileges and system compromise
• Lack of explicit reset parameter allows for exploitation without prior knowledge of account details
• Verification of affected versions and exposure is necessary for prioritization

Technical summary

The vulnerability exists in the /api/json/user/password/update/ endpoint of Integrics Enswitch versions 3.13 through 4.4. By omitting the reset parameter, unauthenticated attackers can change account passwords. This is particularly impactful for accounts with no pending reset, as their empty reset_key matches the defaulted empty value. Attackers can target administrator accounts after enumerating valid usernames.

Defensive priority

High priority for patching and verifying affected systems

Recommended defensive actions

• Patch affected Integrics Enswitch systems to version 4.5 or later
• Verify and restrict access to the Password Reset API
• Monitor for suspicious password reset attempts
• Implement additional authentication and authorization controls
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
