Fortinet Discovers Oracle Subdomain Takeover Vulnerability
Fortinet's FortiGuard Labs has discovered the eloqua.com subdomain takeover vulnerability.
Eloqua.com is part of Oracle, an American multinational computer technology company.
The subdomain takeover vulnerability is caused by a misconfigured DNS entry. It exists because Eloqua.com is using the Microsoft Azure Domain Controller, pointing one of its subdomains to an unregistered Azure subdomain. As a result, it can allow attackers to hijack cookies, bypass Cross-Origin Resource Sharing (CORS), bypass Content-Security Policies (CSP), cheat the password manager applications, intercept emails, etc. by registering the subdomain.
The vendor has fixed the issue since 02/07/2019.
Fortinet reported the vulnerability to Oracle on January 26, 2019.
Oracle confirmed the vulnerability on February 7, 2019.
Oracle patched the vulnerability on February 7, 2019.
This vulnerability was discovered by Zhouyuan Yang of Fortinet's FortiGuard Labs.
