CVE-2020-15843

CVE-2020-15843

ActFax Version 7.10 Build 0335 (2020-05-25) is susceptible to a privilege escalation vulnerability due to insecure folder permissions on %PROGRAMFILES%ActiveFaxClient, %PROGRAMFILES%ActiveFaxInstall and %PROGRAMFILES%ActiveFaxTerminal. The folder permissions allow "Full Control" to "Everyone". An authenticated local attacker can exploit this to replace the TSClientB.exe binary in the Terminal directory, which is executed on logon for every user. Alternatively, the attacker can replace any of the binaries in the Client or Install directories. The latter requires additional user interaction, for example starting the client.

Improper directory permissions in the Hotspot Shield VPN client software for Windows 10.3.0 and earlier may allow an authorized user to potentially enable escalation of privilege via local access. The vulnerability allows a local user to corrupt system files: a local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.
