Security researcher Sam Curry has identified authorization bypass issues in Cox modems, allowing potential unauthorized access and the execution of malicious commands. Following responsible disclosure, the U.S. broadband provider promptly addressed the vulnerabilities. Curry’s analysis revealed potential access to sensitive customer data and the ability to modify device settings, posing significant security concerns.
Based on the meeting notes, the key takeaways are:
1. Authorization bypass issues were discovered in Cox modems, allowing potential unauthorized access and execution of malicious commands.
2. The vulnerabilities were responsibly disclosed and promptly addressed by the U.S. broadband provider, with no evidence of exploitation in the wild.
3. Security researcher Sam Curry highlighted the extensive access that ISPs have to customer devices behind the scenes and the potential for compromising millions of devices.
4. The vulnerabilities included exposed API endpoints that could be exploited to gain administrative functionality and run unauthorized commands.
5. Hypothetically, an attacker could have abused these APIs to retrieve customer account details, Wi-Fi passwords, connected devices, and execute arbitrary commands to take over accounts.
6. Curry emphasized the complexities in managing customer devices and the need for a better authorization mechanism in the REST API.
