DDI-VRT-2017- 05: Remote Unauthenticated Root Command Injection



Vulnerability: Remote Unauthenticated Root Command Injection

Impact: A remote, unauthenticated user could leverage this flaw to gain complete control of an affected asset.

Details: The scripts at /aesvcs/loginErrorPage.xhtml and /aesvcs/login.xhtml do not properly sanitize user input before using it in shell commands. As a result, a remote unauthenticated user could leverage this flaw to inject arbitrary commands which will be executed in the context of the root user. A crafted POST request to these scripts with the "LoginForm%3AuserName" parameter populated with a command injection string can be used to exploit this vulnerability.


The Digital Defense team and Avaya engineers have rated this vulnerability as having a high security impact and recommend Avaya AES users patch their system at the earliest opportunity.
