- Subject: Windows95 Proxy DoS Vulnerabilites
-
- While playing with a proxy server the other day, I have accidently stumbled
- across two remote bugs in numerous proxy servers. Those affected are
- "WinGate and StarTech". Both companies have been previously notified of
- their vulnerability, and in WinGate's case I guess it has been patched
- already.
-
- The bug is pretty straight forward, telnet to the proxy server at its
- pop3 port and type
-
- For WinGate:
- USER x#99999.....
-
- With lots of nine's, the proxy server stops responding and needs to
- be restarted.
-
- For Startech:
- USER x<9999999.....>
-
- Once again, as many nines as possible, startech quits responding.
-
- In Startech's case, this can also be done in the telnet daemon part of
- it also...
-
- Havent tried much others...
-
- My Startech proxy server did not have a version number on it, and the
- Wingate's wasn't available. Sorry, I will try to get this in tommarrow
- if neccessary...
