There are Brute Force and Cross-Site Request Forgery vulnerabilities in TP-Link TL-WR841N and TL-WR841ND. ------------------------- Affected products: ------------------------- Vulnerable are the next models: TP-Link TL-WR841N and TL-WR841ND, Firmware Version 3.16.9 Build 151216. All other versions also must be vulnerable. ---------- Details: ---------- Brute Force (WASC-11): http://192.168.0.1 No protection from BF attacks in login form. By default access from Internet is closed, so it's possible to pick up password only via LAN. But via CSRF attacks it's possible to open remote access. Cross-Site Request Forgery (WASC-09): In section Remote Control. Turn off access via Internet: http://192.168.0.1/YVNLOORCJBATZQDB/userRpm/ManageControlRpm.htm?port=80&ip=0.0.0.0&Save=1 Turn on access via Internet: http://192.168.0.1/YVNLOORCJBATZQDB/userRpm/ManageControlRpm.htm?port=80&ip=255.255.255.255&Save=1 For protection bypass it's needed to set Referer header and path (YVNLOORCJBATZQDB), that changes every time at login to admin panel. This path can be found through information leakage, social engineering or XSS vulnerabilities in admin panel. Cross-Site Request Forgery (WASC-09): Logout from admin panel via request to page http://192.168.0.1. <img src="http://192.168.0.1"> I mentioned about these vulnerabilities at my site (http://websecurity.com.ua/8485/).
