A vulnerability has been identified in SIMATIC WinCC OA V3.15 (All versions < V3.15 P038), SIMATIC WinCC OA V3.16 (All versions < V3.16 P035), SIMATIC WinCC OA V3.17 (All versions < V3.17 P024), SIMATIC WinCC OA V3.18 (All versions < V3.18 P014). The affected component allows to inject custom arguments to the Ultralight Client backend application under certain circumstances.
