Hi@all #### General Information ## Report history: Since 01.05. we have contacted the support of Vodafone 3 times. There has been no response until today. Toady we release the vulnerabilities in hope that Vodafone will react. ## Vendor Information: Vodafone is worldwide operating ISP. Quotation of vodafone.com - about us: " Today, more than 400 million customers around the world choose us. In 30 years, a small mobile operator in Newbury has grown into a global business and one of the most valuable brands in the world. We now operate in around 30 countries and partner with networks in over 50 more. " ## Affected products: EasyBox 804 in all versions and perhaps other product models. EasyBox 804 is shipped to german private customers default. We were not able to verify other countries and business customers default box. We were not able to test other models, because vodafone have not shown any reaction. #### Vuln 1 DoS Combined with this vulnerability it is possible to disable authentication for Vuln 2. This is a combined attack. CVSSv3: 6.5 (AV:A,AC:L,PR:N,UI:N,S:U,C:N,I:N,A:H) Credits: Tim Schughart, ProSec Networks Affected firmware versions: All Patch available: No PoC: You have to browse to the web interface of the router, default is http://192.168.2.1 - here you just need to click on forgot password. This results, in an factory reset, after you have entered the captcha code. The Box is DoS, because you have to refill all needed data for connecting to Vodafone, but thats not all - here is an problem, you'll find in vuln 2. #### Vuln 2 (Infected Firmware upload & Authentication Bypass) For upgrading an Firmware you have to be authenticated - but after exploiting vuln 1, this authentication is disabled - so you are able to upload an modified firmware. CVSSv3: 8.3 (AV:A,AC:H,PR:N,UI:N,S:C,I:H,A:H) Credits: Tim Schughart, ProSec Networks Affected firmware versions: All Patch available: No PoC: You have to exploit Vuln 1 before. After this the authentication for firmware upgrades has been bypassed and you are able to upload any infected firmware you want. Because the code of EasyBox is OpenSource - it's much easier to modify it. You just need to click on "Firmware update" - thats all.
