CVE-2020-7034Network attack vector

Authenticated command execution via crafted messages

Published Apr 23, 2021 · Updated Sep 16, 2024

OS command injection in Avaya SBCE 7.x and 8.0 through 8.1.1.x allows remote authenticated users to execute arbitrary commands. Avaya has not published the affected message handler or how crafted messages reach an operating-system command without sufficient neutralization. Access to an authenticated network interface is required, and successful exploitation runs commands with the affected system's privileges, allowing control over its data and service operation.
