VAR-201802-1251

Vulnerability from variot - Updated: 2024-11-23 23:08

An issue was discovered in PureVPN through 5.19.4.0 on Windows. The client installation grants the Everyone group Full Control permission to the installation directory. In addition, the PureVPNService.exe service, which runs under NT Authority\SYSTEM privileges, tries to load several dynamic-link libraries using relative paths instead of the absolute path. When not using a fully qualified path, the application will first try to load the library from the directory from which the application is started. As the residing directory of PureVPNService.exe is writable to all users, this makes the application susceptible to privilege escalation through DLL hijacking. PureVPN Contains an unreliable search path vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. PureVPN is a paid VPN service. There is a privilege escalation vulnerability in 5.19.4.0 and earlier versions of PureVPN for Windows

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
