Cisco Wide Area Application Services Lets Remote Users Cause the Target Service to Crash
Severity Rating: Medium
Systems Affected:
  • This vulnerability affects Cisco Wide Area Application Services (WAAS).
Description
A vulnerability has been identified in the HTTP web interface for Cisco Wide Area Application Services (WAAS) and could allow an unauthenticated, remote attacker to cause an HTTP Application Optimization (AO) related process to restart, causing a partial denial of service (Denial of Service) condition.
 
The vulnerability is caused due to lack of input validation of user-supplied input parameters within an HTTP request. An attacker could exploit this vulnerability by sending a crafted HTTP request through the targeted device. Successful exploitation of the vulnerability can allow the attacker to cause a DoS condition due to a process unexpectedly restarting. The WAAS could drop traffic during the brief time the process is restarting.
 
Solution
Users are advised to apply updates.
