The IDAL HTTP server is vulnerable to memory corruption through insecure use of user supplied format strings. An attacker can abuse this functionality to bypass authentication or execute code on the server. The IDAL HTTP server does not safely handle username or cookie strings during the authentication process. Attempting to authenticate with the username "%25s%25p%25x%25n" will crash the server. Sending "%08x.AAAA.%08x.%08x" will log memory content from the stack. View the full article

The IDAL HTTP server is vulnerable to a stack-based buffer overflow when receiving a large host header in a HTTP request. The host header value overflows a buffer and overwrites the Structured Exception Handler (SEH) address with a larger buffer. An unauthenticated attacker can send a Host header value of 2047 bytes or more to overflow the host headers and overwrite the SEH address which can then be leveraged to execute attacker controlled code on the server.

The IDAL HTTP server CGI interface contains a URL, which allows an unauthenticated attacker to bypass authentication and gain access to privileged functions. In the IDAL CGI interface, there is a URL (/cgi/loginDefaultUser), which will create a session in an authenticated state and return the session ID along with the username and plaintext password of the user. An attacker can then login with the provided credentials or supply the string 'IDALToken=......' in a cookie which will allow them to perform privileged operations such as restarting the service with /cgi/restart.

The IDAL FTP server is vulnerable to memory corruption through insecure use of user supplied format strings. An attacker can abuse this functionality to bypass authentication or execute code on the server. View the full article

The IDAL FTP server fails to ensure that directory change requests do not change to locations outside of the FTP servers root directory. An authenticated attacker can simply traverse outside the server root directory by changing the directory with "cd ..". An authenticated attacker can traverse to arbitrary directories on the hard disk and then use the FTP server functionality to download and upload files. An unauthenticated attacker can take advantage of the hardcoded or default credential pair exor/exor to become an authenticated attacker. View the full article

The IDAL FTP server is vulnerable to a buffer overflow where a large string is sent by an authenticated attacker that causes a buffer overflow. This overflow is handled, but terminates the process. An authenticated attacker can send a FTP command string of 472 bytes or more to overflow a buffer causing an exception that terminates the server. An unauthenticated attacker can take advantage of the hardcoded or default credential pair exor/exor to become an authenticated attacker. View the full article
