WebNMS Framework Server Credential Disclosure



This module abuses two vulnerabilities in WebNMS Framework Server 5.2 to extract all user credentials. The first vulnerability is an unauthenticated file download in the FetchFile servlet, which is used to download the file containing the user credentials. The second vulnerability is that the passwords in the file are obfuscated with a very weak algorithm which can be easily reversed. This module has been tested with WebNMS Framework Server 5.2 and 5.2 SP1 on Windows and Linux.

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/http/webnms_cred_disclosure
msf auxiliary(webnms_cred_disclosure) > show actions
msf auxiliary(webnms_cred_disclosure) > set ACTION < action-name >
msf auxiliary(webnms_cred_disclosure) > show options
    ...show and set options...
msf auxiliary(webnms_cred_disclosure) > 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.
