Working Resources BadBlue Unauthorized HTS Access Vulnerability

BadBlue is prone to a vulnerability that could allow remote attackers to gain unauthorized access to administrative functions.

It is possible to bypass BadBlue security checks when '.hts' files are requested by a remote user. BadBlue restricts access to non-HTML files by replacing the first two letters in the file extension of a requested resource with 'ht'. If the third character of a file extension is 's', then it is possible to trick BadBlue into serving a non-HTML file with an extension of '.hts'. This will bypass other security checks which would normally prevent BadBlue from serving these files to remote users.
