Description |
The msfweb component of the Metasploit Framework contains a flaw that allows a remote attacker to bypass "defanged mode" security restrictions. The issue is due to a logic error in the msfweb server, allowing a remote user to overwrite the internal "_Defanged" environment variable before the security check is performed.
