Vulnerability in Heimdalsecurity Heimdal
CVE-2018-5349
A vulnerability has been found in Heimdal PRO v2.2.190, but it is most likely also present in Heimdal FREE and Heimdal CORP. Faulty permissions on the directory "C:\ProgramData\Heimdal Security\Heimdal Agent" allow BUILTIN\Users to write new files to the directory. On startup, the process Heimdal.MonitorServices.exe running as SYSTEM will attempt to load version.dll from this directory. Placing a malicious version.dll in this directory will result in privilege escalation. NOTE: any affected Heimdal products are completely unrelated to the Heimdal vendor of a Kerberos 5 product on the h5l.org web site.
