CVE-2024-24795 describes a medium-severity vulnerability found in the Apache HTTP Server. This vulnerability allows an attacker to exploit HTTP Response Splitting in multiple modules. It poses a significant risk as it may enable malicious actors to inject harmful response headers into backend applications, leading to HTTP desynchronization attacks. With a CVSS score of 6.3, it is crucial for organizations to recognize the potential impact and urgency of addressing this vulnerability.
The vulnerability affects various products from multiple vendors, including Apache, Apple, Broadcom, Debian, Fedora, and NetApp. As the issue can lead to unauthorized access or data manipulation, organizations utilizing these products should prioritize remediation. Users are recommended to upgrade to version 2.4.59 of the Apache HTTP Server, which addresses this critical issue.
With no known exploits at present, the situation remains stable. However, the potential for exploitation exists, placing organizations at risk. Organizations should prioritize patching immediately to mitigate potential impacts and safeguard their applications.
The urgency is heightened by the nature of the vulnerability, which could lead to significant operational disruptions if left unaddressed. Security teams should not only apply the necessary patches but also conduct a thorough review of their systems to ensure that other vulnerabilities are not present.
Vulnerability Details
CVE-2024-24795 is classified as an HTTP Response Splitting vulnerability. It is characterized by the ability of an attacker to inject malicious response headers into backend applications, which can disrupt normal HTTP operations. The official description states that it allows for HTTP desynchronization attacks, which could potentially lead to unauthorized actions or access.
The CVSS score of 6.3 indicates a medium severity level, attributed to its attack vector being network-based with low complexity. The attack requires no privileges and necessitates user interaction, indicating that the attacker must trick the user into performing an action that exploits the vulnerability.
This vulnerability affects multiple products from various vendors, including Apache HTTP Server, Debian Linux, Fedora, and macOS. It was published on April 4, 2024, and is classified under CWE-113 (HTTP Response Splitting) and CWE-444 (Inclusion of Functionality from Untrusted Control Sphere).
Technical Analysis
The root cause of CVE-2024-24795 lies in the improper handling of HTTP responses within the Apache HTTP Server. Attackers may leverage this vulnerability by injecting malicious headers into responses sent to users. This process can create a desynchronization between the client and server, leading to potential attacks that manipulate user sessions or extract sensitive information.
The attack vector is network-based, and the attack complexity is rated as low, meaning that it can be executed with relative ease. No privileges are required to perform the attack, but user interaction is necessary, as the attacker must induce a user to send a specially crafted request that exploits the vulnerability.
The impacts of a successful exploit include low confidentiality, integrity, and availability impact, which means that while the immediate effects might seem limited, the potential for significant disruption exists if exploited in conjunction with other vulnerabilities.
Risk & Impact Analysis
Organizations utilizing affected systems face several risks associated with CVE-2024-24795. The ability for attackers to perform HTTP desynchronization attacks can lead to unauthorized access and manipulation of responses, ultimately resulting in loss of customer trust and potential regulatory consequences.
The blast radius of this vulnerability extends across multiple platforms including Debian, Fedora, and macOS, increasing the urgency for organizations to address it across all environments where these operating systems are deployed. Although the exploit status is currently low, the risk remains medium due to the potential for future exploitation as awareness of the vulnerability grows.
Organizations should address this vulnerability in their priority patch cycle. The CVSS score reflects the need for prompt action, as unpatched systems can be subjected to various forms of attacks, leading to severe repercussions.
