Vulnerable System:
Webseries Payment Application
Vulnerability Title:
Password Policy Implemented At Client rather than Server
Vulnerability discovery and development:
Portcullis Security Testing Services
Affected systems:
Bottomline Webseries Payment Application
Details:
The password policy, enforcing the minimum length of passwords, is
implemented in the client browser using JavaScript which can be bypassed
using any local proxy system, allowing for single character passwords.
Impact:
Whilst client side data validation can be of assistance in aiding a user
to correctly enter the required information, client side scripts can be
easily by-passed in a number of ways. This allows a user to set their
password to a value not acceptable to the implemented security policy.
Exploit:
Exploit code not required.
