What to do
AI-suggested
Organizations should immediately assess their use of Mitel MiContact Center Business, focusing on versions up to 10.1.0.4 that include the legacy chat component. Since no official patches are currently listed, mitigation should include disabling or restricting access to the legacy chat feature if feasible. Network segmentation and firewall rules should limit external access to the chat system to trusted internal networks only. Implement strict monitoring and alerting for unusual chat activity or unauthorized message patterns. Educate users about the risk of interacting with unsolicited or suspicious chat messages to reduce the likelihood of successful user interaction exploitation. Engage with Mitel support for updates or patches and apply them promptly once available. Additionally, conduct regular security assessments and penetration tests focused on contact center components to identify and remediate access control weaknesses. Employ multi-factor authentication and session management improvements where possible to further reduce risk.
Description
A vulnerability in the legacy chat component of Mitel MiContact Center Business through 10.1.0.4 could allow an unauthenticated attacker to conduct an unauthorized access attack due to inadequate access control checks. A successful exploit requires user interaction and could allow an attacker to access sensitive information and send unauthorized messages during an active chat session.
