Last modified Jun 17, 2026

CVE-2020-25206 is a high-severity vulnerability rated 7.2/10 on the CVSS scale. The web console for Mimosa B5, B5c, and C5x firmware through 2.8.0.2 allows authenticated command injection in the Throughput, WANStats, PhyStats, and QosStats API classes. An attacker with access to a web console account may execute operating system commands on affected devices by sending crafted POST requests to the affected endpoints (/core/api/calls/Throughput.php, /core/api/calls/WANStats.php, /core/api/calls/PhyStats.php, /core/api/calls/QosStats.php). EPSS estimates a 5.31% chance of exploitation in the next 30 days.

Description

The web console for Mimosa B5, B5c, and C5x firmware through 2.8.0.2 allows authenticated command injection in the Throughput, WANStats, PhyStats, and QosStats API classes. An attacker with access to a web console account may execute operating system commands on affected devices by sending crafted POST requests to the affected endpoints (/core/api/calls/Throughput.php, /core/api/calls/WANStats.php, /core/api/calls/PhyStats.php, /core/api/calls/QosStats.php). This results in the complete takeover of the vulnerable device. This vulnerability does not occur in the older 1.5.x firmware versions.
