Technical details

IBM Aspera Faspex 5 is vulnerable to an OS command injection (CWE-78) within its web interface. A remote authenticated attacker with high privileges (PR:H) can exploit this vulnerability by sending specially crafted input to the application, which is then improperly neutralized before being passed to a system shell. Successful exploitation allows the attacker to execute arbitrary commands on the underlying operating system with the privileges of the application process. This vulnerability is addressed in IBM Aspera Faspex version 5.0.16.
