Github Enterprise Default Session Secret And Deserialization Vulnerability



This module exploits two security issues in Github Enterprise, version 2.8.0 - 2.8.6. The first is that the session management uses a hard-coded secret value, which can be abused to sign a serialized malicious Ruby object. The second problem is due to the use of unsafe deserialization, which allows the malicious Ruby object to be loaded, and results in arbitrary remote code execution. This exploit was tested against version 2.8.0.

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 exploit/linux/http/github_enterprise_secret
msf exploit(github_enterprise_secret) > show targets
msf exploit(github_enterprise_secret) > set TARGET < target-id >
msf exploit(github_enterprise_secret) > show options
    ...show and set options...
msf exploit(github_enterprise_secret) > exploit

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.
