Apache HTTP Server Update Patches Critical Source Code Disclosure Flaw (CVE-2024-39884)

Recently, the Apache Software Foundation has rushed to release Apache HTTP Server version 2.4.61, a crucial update that addresses a severe source code disclosure vulnerability (CVE-2024-39884). This flaw, rated as “Important” by the Apache team, could expose sensitive server-side information to malicious actors.

The CVE-2024-39884 vulnerability stems from a regression in the handling of legacy content-type based configurations. Specifically, the “AddType” directive and similar settings, when used under specific circumstances, could inadvertently reveal the source code of files intended to be processed. This could include server-side scripts, configuration files, or other sensitive data.

While source code disclosure might seem like a technical concern, the implications can be far-reaching. Attackers could exploit this vulnerability to:

• Gain a deeper understanding of the server environment: This could pave the way for more sophisticated attacks targeting specific software versions or configurations.
• Identify vulnerabilities in the revealed code: This could lead to further exploitation, potentially compromising the entire server or connected systems.
• Steal sensitive data: If the exposed code contains database credentials, API keys, or other confidential information, the consequences could be disastrous.

The Apache team urges all users of Apache HTTP Server 2.4.60 to immediately upgrade to version 2.4.61. This update not only patches the source code disclosure flaw but also addresses several other vulnerabilities and bugs discovered in the previous version.

For further information on the vulnerabilities fixed in Apache HTTP Server 2.4.61, refer to the official security advisory on the Apache website. Additionally, consider implementing additional security measures such as web application firewalls, intrusion detection systems, and regular vulnerability scanning to fortify your defenses against evolving threats.
