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.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
