| Description | Punto Switcher through 4.5.0.583 contains an unquoted search path element vulnerability that allows local attackers to execute arbitrary code by exploiting the application's call to WinExec without a fully qualified path for RunDll32.exe when invoking shell32.dll Control_RunDLL input.dll. Attackers can place a malicious executable earlier in the search order to achieve arbitrary code execution in the context of the affected user. |
