Vulnerability Overview

WordPress before 4.5 does not consider octal and hexadecimal IP address formats when determining an intranet address, which allows remote attackers to bypass an intended SSRF protection mechanism via a crafted address.

Technical Analysis

REMEDIATION: Update to version 4.5, or a newer patched version --- IDENTIFIER: CWE-918 (Server-Side Request Forgery (SSRF)) The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
