Privilege escalation via writable client executable
Published Apr 27, 2021 · Updated Aug 3, 2024
Improper permissions in Soyal Technology 701Client 9.0.1 allow local users to gain elevated privileges by replacing client.exe. The client.exe access-control list grants the Authenticated Users group Full control, allowing any authenticated account to overwrite the executable. A substituted binary executes when the client is subsequently launched, placing execution in the launching account's security context.
