Vulnerability title: Vertical Privilege Escalation in Symmetricom s350i

CVE: CVE-2014-5070
Vendor: Symmetricom
Product: s350i
Affected version: 2.70.15
Fixed version: N/A
Reported by: Mike Emery


The Team discovered that unauthenticated user could access web application functionality and content for higher privilege users. This issue affected all the functionality within the application. The issue resides in the code that pushes unauthenticated users back to the login page, in that it does not prevent the unauthenticated request from being processed.

Note: Whilst the application correctly detects whether the user making the request has successfully authenticated and has a valid session, it continues to process the users’ request even having detected that a user is not logged in.


This type of privilege escalation occurs when a user or process is able to obtain a higher level of access than an administrator or system developer intended. In addition, a lack of input validation could enable an attacker to exploit any flaw allowing unauthorised code to run with application privileges.
