Overview<\/strong><\/p>\n

This report provides an in-depth analysis of the CVE-2024-42516, a significant security vulnerability detected in the Apache HTTP Server. This vulnerability, if exploited, allows an attacker to manipulate the Content-Type response headers of applications, potentially leading to a system compromise or data leakage. As Apache HTTP Server is widely used across multiple platforms and industries, understanding and addressing this vulnerability is of utmost importance.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2024-42516
\nSeverity: High (CVSS: 7.5)

Product | Affected Versions<\/p>\n

Apache HTTP Server | 2.4.59<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability CVE-2024-42516 is an HTTP response splitting flaw located in the core of Apache HTTP Server. An attacker exploiting this vulnerability can manipulate the Content-Type response headers of applications hosted or proxied by the server, thereby splitting the HTTP response. This splitting can potentially be used to trick the server into sending arbitrary responses, resulting in cache poisoning, cross-user defacement, cross-site scripting, or even potential remote code execution.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a high-level conceptual example of how this vulnerability might be exploited:<\/p>\n

GET \/vulnerable\/endpoint HTTP\/1.1\nHost: target.example.com\nContent-Type: text\/html; charset=UTF-8%0D%0ASet-Cookie:%20malicious_cookie=malicious_value<\/code><\/pre>\n
In the above example, the attacker manipulates the ‘Content-Type’ header to insert a ‘Set-Cookie’ header into the response. This allows the attacker to set a malicious cookie on a client’s browser.<\/p>\n
Mitigation<\/strong><\/p>\n
Users are recommended to upgrade to Apache HTTP Server version 2.4.64, which includes a patch for this vulnerability. In the interim, employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may serve as temporary mitigation strategies.<\/p>\n","protected":false},"excerpt":{"rendered":"
