Hello list! I want to warn you about new multiple security vulnerabilities in ADSL modem Callisto 821+ (SI2000 Callisto821+ Router). These are Cross-Site Request Forgery and Cross-Site Scripting vulnerabilities. In April I've already drew attention of Ukrtelecom's representative (and this modem was bough at Ukrtelecom) about multiple vulnerabilities in this model of Callisto modems (and other models also could be affected). SecurityVulns ID: 11700. ------------------------- Affected products: ------------------------- Vulnerable is the next model: SI2000 Callisto821+ Router: X7821 Annex A v1.0.0.0 / Argon 4x1 CSP v1.0 (ISOS 9.0) [4.3.4-5.1]. This model with other firmware and also other models of Callisto also must be vulnerable. ---------- Details: ---------- These attacks should be conducted on modem owner, which is logged into control panel. Taking into account that it's unlikely to catch him in this state, then it's possible to use before-mentioned vulnerabilities (http://websecurity.com.ua/5161/) for conducting of remote login (for logining him into control panel). After that it's possible to conduct CSRF or XSS attack. CSRF (WASC-09): In section LAN connection: Ethernet routed (http://192.168.1.1/configuration/lan_create_service.html?EmWeb_ns:vim:3=/configuration/lan_ether_routed.html) it's possible to add connection. In section LAN connection: Ethernet bridged (http://192.168.1.1/configuration/lan_create_service.html?EmWeb_ns:vim:3=/configuration/lan_ether_bridged.html) it's possible to add connection. In section LAN connections (http://192.168.1.1/configuration/lan.html) the functionality of editing and deleting connections also must be vulnerable to CSRF. But because in my modem the functionality of creating connections worked incorrectly (it was not possible to create them), then there was no possibility to check it. XSS (WASC-08): There are many persistent XSS vulnerabilities in above-mentioned functionalities. http://192.168.1.1/configuration/lan_create_service.html?EmWeb_ns:vim:9=%3Cscript%3Ealert(document.cookie)%3C/script%3E http://192.168.1.1/configuration/lan_create_service.html?EmWeb_ns:vim:10=%3Cscript%3Ealert(document.cookie)%3C/script%3E http://192.168.1.1/configuration/lan_create_service.html?EmWeb_ns:vim:11=%3Cscript%3Ealert(document.cookie)%3C/script%3E http://192.168.1.1/configuration/lan_create_service.html?EmWeb_ns:vim:15=%3Cscript%3Ealert(document.cookie)%3C/script%3E And also attacks via the names of parameters (when XSS code is setting in the name of parameter), which I wrote about earlier (http://websecurity.com.ua/5277/). In this case the code will be executed immediately, and also at visiting of pages http://192.168.1.1/system/events.html and http://192.168.1.1/shared/event_log_selection.html. In section LAN connection: Ethernet routed (http://192.168.1.1/configuration/lan_create_service.html?EmWeb_ns:vim:3=/configuration/lan_ether_routed.html) there are persistent XSS vulnerabilities in some text fields and some hidden fields (including XSS attacks via the names of parameters). In this case the code will be executed immediately, and also at visiting of pages http://192.168.1.1/system/events.html and http://192.168.1.1/shared/event_log_selection.html. And in case of some fields XSS code will execute at page http://192.168.1.1/configuration/lan.html. In section LAN connection: Ethernet bridged (http://192.168.1.1/configuration/lan_create_service.html?EmWeb_ns:vim:3=/configuration/lan_ether_bridged.html) there are persistent XSS vulnerabilities in some text fields and some hidden fields (including XSS attacks via the names of parameters). In this case the code will be executed immediately, and also at visiting of pages http://192.168.1.1/system/events.html and http://192.168.1.1/shared/event_log_selection.html. And in case of some fields XSS code will execute at page http://192.168.1.1/configuration/lan.html. I mentioned about these vulnerabilities at my site (http://websecurity.com.ua/5281/).
