Mitel

Mitel's vulnerability profile spans a well-represented portfolio of unified communications, contact center, and conferencing products serving enterprise deployments, presenting a significant attack surface across collaboration infrastructure. Vulnerabilities affecting the vendor skew strongly toward critical-severity outcomes and have a meaningful tendency toward both confirmed in-the-wild exploitation and public exploit availability, reflecting the internet-facing and authentication-sensitive nature of these systems. The exposure recurs across products such as MiCollab, MiVoice Connect, and MiContact Center Business through weakness classes including cross-site scripting, SQL injection, improper input validation, and code injection—characteristic of web-centric and database-integrated platforms where input handling and output encoding are persistently challenging. Defenders should prioritize patches for internet-reachable collaboration and contact center instances and treat this vendor's advisories as high-priority for systems handling sensitive communications. Current exploitation activity and exposure counts are shown alongside this summary.
