CVE-2020-25206Network attack vector

Authenticated device takeover via API command injection

Published Jul 20, 2021 · Updated Aug 4, 2024

Command injection in Mimosa B5, B5c, and C5x firmware through 2.8.0.2 allows remote authenticated users to take over devices. The Throughput, WANStats, PhyStats, and QosStats web-console API classes pass crafted POST input into operating system commands without neutralizing command syntax. A valid web-console account is required; successful injection executes arbitrary operating system commands and grants complete control of the appliance.
