You can use any web browser you like to login to the Huawei B660. (Copy of the Homepage: http://setuprouter.com/router/huawei/b660/manual-1184.pdf ) Abstract Advisory Information: ============================== The vulnerability laboratory core research team discovered a security flaw that affects the official Huawei Flybox B660 3G/4G router product series. Vulnerability Disclosure Timeline: ================================== 2017-01-10: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Huawei Product: Flybox - Router (Web-Application) B660 3G/4G Exploitation Technique: ======================= Remote Severity Level: =============== Medium Technical Details & Description: ================================ A remote cross-site request forgery (CSRF) vulnerability has been discovered in the official Huawei Flybox B660 3G/4G router product series. The security vulnerability allows remote attackers to submit special requests to the affected product which could lead reboot the Product. The vulnerability is located in the `/htmlcode/html/reboot.cgi` and `/htmlcode/html/system_reboot.asp` file modules and `RequestFile` parameter of the localhost path URL. Remote attackers are able to reboot any Huawei Flybox B660 via unauthenticated POST method request. The security risk of the csrf web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 4.4. Exploitation of the csrf web vulnerability requires a low privilege web-application user account and medium or high user interaction. Successful exploitation of the vulnerability results in unauthenticated application requests and manipulation of affected or connected device backend modules. Request Method(s): [+] POST Vulnerable Module(s): [+] /htmlcode/html/reboot.cgi [+] /htmlcode/html/system_reboot.asp Vulnerable Parameter(s): [+] RequestFile Software version of the modem: 1066.12.15.01.200 Hardware version of the modem: WLB3TCLU Name of the device: B660 Hardware version of the router: WL1B660I001 Software version of the router: 1066.11.15.02.110sp01 Proof of Concept (PoC): ======================= The security vulnerability can be exploited by remote attackers without privilege web-application user account and with medium or high user interaction. For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue. --- PoC Session Logs --- POST /htmlcode/html/reboot.cgi?RequestFile=/htmlcode/html/system_reboot.asp HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101 Firefox/31.0 Iceweasel/31.4.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Referer: localhost/htmlcode/html/system_reboot.asp Connection: keep-alive Content-Type: application/x-www-form-urlencoded Content-Length: 0 HTTP/1.1 200 OK CACHE-CONTROL: no-cache Content-Type: text/html Content-Length: 364 replace Note: Attacker are able to reboot the device itself without being authenticated to it . Also an Attacker can put an auto-submit javascript-generated form inside an high traffic website to compromise. PoC: CSRF Exploit Security Risk: ============== The security risk of the cross site request forgery vulnerability in the Huawei Flybox B660 3G/4G router product series is estimated as medium.
