Ladda ner SysManager 1.52.91

[1.52.91] - 2026-07-11
Fixed
- WindowsFeaturesService launched PowerShell by the extension-less name "powershell", defeating the System32 path-pinning that blocks binary-planting privilege escalation on an elevated code path. All three call sites (ListFeaturesAsync, EnableFeatureAsync, DisableFeatureAsync — the enable/disable paths run elevated) called RunProcessAsync("powershell", …). PowerShellRunner hardens the target via SystemPaths.ResolveSystemTool, but that helper resolved by File.Exists and only ever probed the bare name — File.Exists(@"…\System32\WindowsPowerShell\v1.0\powershell") is false (the file is powershell.exe), so both probes missed and it returned the unrooted "powershell". With UseShellExecute=false, Win32 CreateProcess then searches the calling process's own directory first — so an attacker-planted powershell.exe next to SysManager's portable .exe (often run from a user-writable folder, sometimes elevated) would execute with the app's privileges. Changed all three sites to "powershell.exe" (matching PowerShellRunner.RunScriptViaPwshAsync and every other system-tool caller, which all use the .exe suffix). Fix-the-class: SystemPaths.ResolveSystemTool now also probes "<name>.exe" when given an extension-less bare name, so a future caller that forgets the suffix can't silently reopen the same hole.
