Description
In WinRAR versions prior to and including 5.61, there is path traversal vulnerability when crafting the filename field of the ACE format (in UNACEV2.dll). When the filename field is manipulated with specific patterns, the destination (extraction) folder is ignored, thus treating the filename as an absolute path. This module will attempt to extract a payload to the startup folder of the current user. It is limited such that we can only go back one folder. Therefore, for this exploit to work properly, the user must extract the supplied RAR file from one folder within the user profile folder (e.g. Desktop or Downloads). User restart is required to gain a shell.
Module options
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use exploit/windows/fileformat/winrar/acemsf undefined(ace) > show actions ...actions...msf undefined(ace) > set ACTION < action-name >msf undefined(ace) > show options ...show and set options...msf undefined(ace) > runPrioritise with Active Threat Intelligence
