3cx

3CX maintains a focused portfolio of unified communications and call-center products, including its phone system, web server, and live chat platform, that sit on the perimeter of enterprise networks and handle sensitive authentication and customer data. Vulnerabilities affecting the vendor skew toward serious outcomes, with an elevated share reaching critical severity and a moderate tendency toward public exploit availability, reflecting the internet-facing nature and feature density of communications middleware. The exposure recurs across the product line through weakness classes including cross-site scripting, path traversal, unsafe file upload, and cleartext storage of credentials, which are characteristic of web-facing communication applications and present direct risks to deployed instances. Defenders should prioritize patching this vendor's releases and inventory instances exposed to untrusted networks, particularly where the platform handles user authentication or customer interactions. Current exploitation activity and exposure counts are shown alongside this summary.
