CVE-2024-38472 is a high-severity vulnerability classified as a Server-Side Request Forgery (SSRF) affecting the Apache HTTP Server on Windows. This vulnerability allows attackers to potentially leak NTLM hashes to a malicious server through specially crafted requests. The CVSS score for this vulnerability is 7.5, indicating a significant risk to affected systems. Organizations using vulnerable versions of Apache HTTP Server must prioritize remediation efforts.
The vulnerability is particularly concerning due to its potential impact on confidentiality, with a high confidentiality impact score. Attackers may leverage this weakness to gain unauthorized access to sensitive information, exposing organizations to data breaches and compliance violations. As of now, exploit availability has been confirmed, which increases the urgency of addressing this vulnerability.
Organizations should prioritize patching immediately. Upgrading to version 2.4.60 of the Apache HTTP Server will mitigate this issue. However, existing configurations that access UNC paths will require a new directive named "UNCList" to allow access during request processing.
Failure to address this vulnerability could lead to severe repercussions, including unauthorized access to sensitive data and potential exploitation of the affected systems by malicious actors.
Vulnerability Details
The official description of CVE-2024-38472 states that it allows an attacker to leak NTLM hashes to a malicious server via SSRF and malicious requests or content. The vulnerability is present in Apache HTTP Server versions prior to 2.4.60.
The CVSS score of 7.5 indicates a high severity level, primarily due to its high confidentiality impact. The attack vector is network-based, with low complexity and no privileges required for exploitation.
The vulnerability was published on July 1, 2024, and is classified under CWE-918, which pertains to Server-Side Request Forgery vulnerabilities.
Technical Analysis
The root cause of this vulnerability lies in the improper validation of requests that access internal resources via UNC paths. This oversight can be exploited by attackers to send crafted requests that may leak sensitive information, such as NTLM hashes, to external servers.
The attack vector is network-based, meaning attackers do not need physical access to the machines. The complexity of the attack is low, as no special privileges or user interaction are required to exploit this vulnerability. The confidentiality impact is high, as sensitive data can be exposed, while integrity and availability impacts remain unaffected.
Risk & Impact Analysis
Risk to organizations includes potential data breaches and unauthorized access to sensitive information. The blast radius can be significant, especially for organizations that rely on the Apache HTTP Server for critical applications.
Given the exploitability of this vulnerability and its critical nature, organizations should address it urgently. The high exploitability score indicates a real and immediate risk of attack.
