The web management interface of Ubiquiti airMAX, airFiber, airGateway and EdgeSwitch XP (formerly TOUGHSwitch) allows an unauthenticated attacker to upload and write arbitrary files using directory traversal techniques. An attacker can exploit this vulnerability to gain root privileges. This vulnerability is fixed in the following product versions (fixes released in July 2015, all prior versions are affected): airMAX AC 7.1.3; airMAX M (and airRouter) 5.6.2 XM/XW/TI, 5.5.11 XM/TI, and 5.5.10u2 XW; airGateway 1.1.5; airFiber AF24/AF24HD 2.2.1, AF5x 3.0.2.1, and AF5 2.2.1; airOS 4 XS2/XS5 4.0.4; and EdgeSwitch XP (formerly TOUGHSwitch) 1.3.2.

Ubiquiti UCRM versions 2.3.0 to 2.7.7 allow an authenticated user to read arbitrary files in the local file system. Note that by default, the local file system is isolated in a docker container. Successful exploitation requires valid credentials to an account with "Edit" access to "System Customization".

Ubiquiti Networks EdgeSwitch version 1.7.3 and prior suffer from an improperly neutralized element in an OS command due to lack of protection on the admin CLI, leading to code execution and privilege escalation greater than administrators themselves are allowed. An attacker with access to an admin account could escape the restricted CLI and execute arbitrary shell instructions.

Ubiquiti Networks EdgeOS version 1.9.1 and prior suffer from an Improper Privilege Management vulnerability due to the lack of protection of the file system leading to sensitive information being exposed. An attacker with access to an operator (read-only) account could escalate privileges to admin (root) access in the system.

Ubiquiti Networks EdgeOS version 1.9.1 and prior suffer from a Cross-Site Request Forgery (CSRF) vulnerability. An attacker with access to an operator (read-only) account could lure an admin (root) user to access the attacker-controlled page, allowing the attacker to gain admin privileges in the system.

Ubiquiti Networks EdgeOS version 1.9.1.1 and prior suffer from an Improper Privilege Management vulnerability due to the lack of validation on the input of the Feature functionality. An attacker with access to an operator (read-only) account and ssh connection to the devices could escalate privileges to admin (root) access in the system.
