An attacker can abuse this issue to bypass Application Whitelisting in order to run arbitrary code on the target machine. ------------------------------------------------------------------------ Tested versions ------------------------------------------------------------------------ This issue was successfully verified on Ivanti Workspace Control version 10.2.700.1. ------------------------------------------------------------------------ Fix ------------------------------------------------------------------------ This issue was resolved in Ivanti Workspace Control version 10.2.950.0. PowerGrid now uses the GetSystemDirectory() function to construct an absolute path to rundll32.exe. ------------------------------------------------------------------------ Details ------------------------------------------------------------------------ https://www.securify.nl/advisory/SFY20180801/ivanti-workspace-control-application-whitelist-bypass-via-powergrid-_rws-command-line-argument.html _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
