Description

The version of FlexNet License Manager installed on the remote Windows host is earlier than 11.10.0.3. As such, it is potentially affected by multiple vulnerabilities :

  • Multiple problems exist that allow an attacker to

influence the saving and loading of log files on the

server. By utilizing a directory traversal issue and

some file renaming bugs, an attacker can leverage these

vulnerabilities to execute arbitrary code subject to

the user running the affected application.

  • A buffer overflow vulnerability exists that coul lead to

arbitrary code execution.
