Mirasys · Mirasys Vms · CVE-2019-11029
**Name of the Vulnerable Software and Affected Versions**
Mirasys VMS versions prior to 7.6.1
Mirasys VMS versions 8.x prior to 8.3.2
**Description**
The issue concerns the mishandling of the `Download()` method of `AutoUpdateService` in `SMServer.exe`, leading to Directory Traversal. An attacker could use `..` with this method to iterate over lists of interesting system files and download them without previous authentication. This includes SAM-database backups, `Web.config` files, etc., and might cause a serious impact on confidentiality.
**Recommendations**
For versions prior to 7.6.1, update to version 7.6.1 or later.
For versions 8.x prior to 8.3.2, update to version 8.3.2 or later.
