Patched on 2nd July 2018 in version 5.1.8.
Dennis Herrmann and Malte Poll
This vulnerability allows remote attackers to execute arbitrary code in SeedDMS (formerly LetoDMS and MyDMS) before 5.1.8 by adding an system command at the end of the "cacheDir" path and following usage of the "Clear Cache" functionality. This allows an authenticated attacker, with permission to the Settings functionality, to inject arbitrary system commands within the application by manipulating the "Cache directory" path. An attacker can use it to perform malicious tasks such as to extract, change, or delete sensitive information or run system commands on the underlying operating system.
