Cisco Secure ACS Unauthorized Password Change



This module exploits an authentication bypass issue which allows arbitrary password change requests to be issued for any user in the local store. Instances of Secure ACS running version 5.1 with patches 3, 4, or 5 as well as version 5.2 with either no patches or patches 1 and 2 are vulnerable.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/admin/networking/cisco_secure_acs_bypass
msf auxiliary(cisco_secure_acs_bypass) > show actions
msf auxiliary(cisco_secure_acs_bypass) > set ACTION < action-name >
msf auxiliary(cisco_secure_acs_bypass) > show options
    ...show and set options...
msf auxiliary(cisco_secure_acs_bypass) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
