CWE-20

Summary

A vulnerability in the web interface that is used to update the system time on
Cisco Small Business 500 Series Wireless Access Point devices could allow an 
unauthenticated, remote attacker to impact the integrity of a system.

The vulnerability is due to insufficient validation of user-controlled 
parameters in HTTP POST requests. An attacker could exploit this vulnerability
by sending an HTTP POST request with crafted user parameters that update the 
system time maliciously. An exploit could allow the attacker to impact the 
integrity of the system because the user parameters are not properly 
validated.

Cisco has not released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
