CVE-2023-38709 is a high-severity vulnerability affecting the Apache HTTP Server, specifically through version 2.4.58. This vulnerability allows attackers to exploit faulty input validation within the server's core functions, leading to potential HTTP response splitting. The implications of this vulnerability are significant, as they can compromise the integrity of web applications using the affected server, allowing unauthorized manipulation of HTTP responses.
With a CVSS score of 7.3, this vulnerability is classified as high severity. The low attack complexity and lack of required privileges or user interaction mean that it can be exploited easily by attackers. Organizations running affected versions of Apache HTTP Server should prioritize remediation to mitigate potential risks of data exposure and unauthorized access.
Risk to organizations includes HTTP response splitting, which can lead to session hijacking, cache poisoning, and other forms of unauthorized access. Given the ease of exploitation, organizations are urged to implement patches immediately to protect their systems.
As of the latest data, there is no known public exploit for this vulnerability, but it remains critical for organizations to stay vigilant and ensure that their systems are updated with the latest security patches. The urgency of addressing this vulnerability cannot be overstated.
Vulnerability Details
Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators to split HTTP responses. This issue affects Apache HTTP Server: through 2.4.58.
The CVSS score for this vulnerability is 7.3, indicating high severity, which signifies a potential for significant impact if exploited. The affected products include Apache HTTP Server, as well as various operating systems like Debian and Fedora that utilize vulnerable versions of the Apache server.
Technical Analysis
The root cause of CVE-2023-38709 lies in the lack of proper input validation mechanisms within the Apache HTTP Server. Attackers can exploit this weakness to manipulate HTTP responses, potentially leading to various attacks such as cache poisoning or content spoofing.
The attack vector is network-based, with low complexity and no required privileges or user interaction, making it easy for attackers to exploit this vulnerability remotely. The impacts on confidentiality, integrity, and availability are all rated as low, but the potential for exploitation remains concerning.
Risk & Impact Analysis
Real-world deployment of the affected versions of Apache HTTP Server presents a significant risk to organizations, particularly those with publicly accessible services. The potential for HTTP response splitting can lead to serious breaches, including unauthorized access to sensitive information and manipulation of user sessions.
The urgency of addressing this vulnerability is underscored by its high CVSS score and the ease of exploitation. Organizations should prioritize patching this vulnerability to prevent possible exploitation and safeguard their web applications.
