CVE-2023-24623 : Security Advisory and Response

This CVE-2023-24623 involves Paranoidhttp before version 0.3.0, allowing Server-Side Request Forgery (SSRF) due to an issue where [::] is treated as equivalent to the 127.0.0.1 address, bypassing the filter for private addresses.

Understanding CVE-2023-24623

This section will delve into the details of CVE-2023-24623, discussing what the vulnerability entails and its potential impact.

What is CVE-2023-24623?

The CVE-2023-24623 vulnerability is found in Paranoidhttp versions prior to 0.3.0, where SSRF can occur because [::] is considered the same as the 127.0.0.1 address but is not recognized by the filter designed for private addresses.

The Impact of CVE-2023-24623

The impact of this vulnerability lies in the potential for an attacker to exploit SSRF, allowing them to make requests on behalf of the server, potentially leading to unauthorized access to internal systems or sensitive data.

Technical Details of CVE-2023-24623

In this section, we will explore the technical aspects of CVE-2023-24623, including the vulnerability description, affected systems and versions, and the exploitation mechanism.

Vulnerability Description
