A vulnerability has been identified in RUGGEDCOM RST2428P (6GK6242-6PA00) (All versions < V3.2), SCALANCE XCH328 (6GK5328-4TS01-2EC2) (All versions < V3.2), SCALANCE XCM324 (6GK5324-8TS01-2AC2) (All versions < V3.2), SCALANCE XCM328 (6GK5328-4TS01-2AC2) (All versions < V3.2), SCALANCE XCM332 (6GK5332-0GA01-2AC2) (All versions < V3.2), SCALANCE XRH334 (24 V DC, 8xFO, CC) (6GK5334-2TS01-2ER3) (All versions < V3.2), SCALANCE XRM334 (230 V AC, 12xFO) (6GK5334-3TS01-3AR3) (All versions < V3.2), SCALANCE XRM334 (230 V AC, 8xFO) (6GK5334-2TS01-3AR3) (All versions < V3.2), SCALANCE XRM334 (230V AC, 2x10G, 24xSFP, 8xSFP+) (6GK5334-5TS01-3AR3) (All versions < V3.2), SCALANCE XRM334 (24 V DC, 12xFO) (6GK5334-3TS01-2AR3) (All versions < V3.2), SCALANCE XRM334 (24 V DC, 8xFO) (6GK5334-2TS01-2AR3) (All versions < V3.2), SCALANCE XRM334 (24V DC, 2x10G, 24xSFP, 8xSFP+) (6GK5334-5TS01-2AR3) (All versions < V3.2), SCALANCE XRM334 (2x230 V AC, 12xFO) (6GK5334-3TS01-4AR3) (All versions < V3.2), SCALANCE XRM334 (2x230 V AC, 8xFO) (6GK5334-2TS01-4AR3) (All versions < V3.2), SCALANCE XRM334 (2x230V AC, 2x10G, 24xSFP, 8xSFP+) (6GK5334-5TS01-4AR3) (All versions < V3.2). The "Load Configuration from Local PC" functionality in the web interface of affected products contains a race condition vulnerability. This could allow an authenticated remote attacker to make the affected product load an attacker controlled configuration instead of the legitimate one. Successful exploitation requires that a legitimate administrator invokes the functionality and the attacker wins the race condition.
