TITLE

Cambium Networks ePMP Command injection vulnerability in some firmware

Trust: 0.8

sources: JVNDB: JVNDB-2017-011728

DESCRIPTION

In version 3.5 and prior of Cambium Networks ePMP firmware, a lack of input sanitation for certain parameters on the web management console allows any authenticated user (including the otherwise low-privilege readonly user) to inject shell meta-characters as part of a specially-crafted POST request to the get_chart function and run OS-level commands, effectively as root. Cambium Networks ePMP Has a command injection vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. CambiumNetworksePMP is a wireless network access platform of Cambium Networks Inc. The platform provides features such as video surveillance, Wi-Fi hotspots and sensor connectivity. A security vulnerability exists in CambiumNetworksePMP using firmware versions 3.5 and earlier, which stems from a failure of the web management console to adequately filter input. An attacker can use this vulnerability to inject shell metacharacters by sending a specially crafted POST request to the \342\200\230get_chart\342\200\231 function to gain access to the administrator, control the device, and the entire WiFi network
