Title: Baltimore Technologies WEBsweeper Restricted Directory Disclosure Vulnerability
Severity: HIGH
Description:
WEBsweeper is an application which implements content security of suspicious filetypes, hidden mailtos, web content, HTTP and FTP transfers, scripts, etc.
WEBsweeper enables the administrator to block remote access to specific web directories. A vulnerability exists in WEBsweeper which could enable a remote user to bypass this feature and gain access to restricted web directories. Requesting such a directory along with specially chosen characters (example: '../' '/./' '//'), could reveal the contents of the known web directory.
Successful exploitation of this vulnerability could lead to the disclosure of private/sensitive data, possibly assisting in further attacks against the target host.
