Summary
Improper input validation in the Netconf service in Infinera MTC-9 allows remote authenticated users to crash the service and reboot the appliance via crafted XML payloads, causing a DoS condition. This issue affects MTC-9 from R22.1.1.0275 before R23.0.
Risk Assessment
An attacker could cause a denial of service (DoS) condition, making the Netconf service unavailable and rebooting the appliance. This may disrupt network operations and dependent services.
Recommendation
