  Gemalto Sentinel License Manager 18.0.1 Directory Traversal Vulnerability     Vendor: Gemalto NV | SafeNet, Inc Product web page: http://www.gemalto.com | http://www.safenet-inc.com Affected version: 18.0.1.55505   Summary: The Sentinel License Manager enforces and manages licensing in multi-user environment. It keeps track of all the licenses and handles requests from network users who want to run your application, granting authorization to the requesters to allow them to run the application, and denying requests when all licenses are in use. It is an integral component of the network licensing schemes that can be implemented with Sentinel RMS, namely server-locked licenses, site licenses and commuter licenses.   Desc: Input passed via the &apos;alpremove&apos; and &apos;check_in_file&apos; parameters is not properly verified in &apos;/_int_/action.html&apos; and &apos;/_int_/checkin_file.html&apos; before being used to delete and create files. This can be exploited to arbitrarily delete sensitive information on a system and/or write files via directory traversal attacks.   Tested on: Microsoft Windows 7 Ultimate SP1 (EN) HASP LM/18.00 (web server)     Vulnerability discovered by Gjoko &apos;LiquidWorm&apos; Krstic @zeroscience     Advisory ID: ZSL-2016-5330 Advisory URL: http://www.zeroscience.mk/en/vulnerabilities/ZSL-2016-5330.php     26.04.2016   --       1.
