CVE-2024-38476: 
Apache HTTP Server vulnerability analysis and mitigation

Overview

A critical vulnerability (CVE-2024-38476) was discovered in Apache HTTP Server versions 2.4.59 and earlier. The vulnerability affects the core functionality of the server and was reported by Orange Tsai (@orange8361) from DEVCORE. The issue was disclosed on July 1, 2024, and was fixed in version 2.4.60 ([Apache Advisory](https://httpd.apache.org/security/vulnerabilities24.html)).

Technical details

The vulnerability allows for information disclosure, Server-Side Request Forgery (SSRF), or local script execution through backend applications whose response headers are malicious or exploitable. The vulnerability has been assigned a CVSS v3.1 base score of 9.8 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating high severity across confidentiality, integrity, and availability impacts (NVD).

Impact

The vulnerability can lead to multiple severe consequences including information disclosure, allowing attackers to access sensitive data, SSRF attacks enabling attackers to make server-side requests to internal resources, and local script execution which could result in unauthorized code execution on the affected system (Apache Advisory, NetApp Advisory).

Mitigation and workarounds

Users are strongly recommended to upgrade to Apache HTTP Server version 2.4.60, which contains the fix for this vulnerability. After the fix, some legacy uses of the 'AddType' directive to connect a request to a handler must be ported to 'SetHandler' (Apache Advisory).
