CVE-2024-45338 is classified as a medium-severity vulnerability with a CVSS score of 5.3. This vulnerability allows an attacker to craft an input to the Parse functions, which would be processed non-linearly concerning its length. As a result, this can lead to extremely slow parsing, causing a denial of service. Organizations should understand the implications of this vulnerability, especially in environments where performance is critical.
The urgency for defenders is moderate due to the potential impact of denial of service on affected systems. Although the vulnerability is not yet known to have exploits in the wild, its characteristics suggest it could be weaponized if not addressed promptly. Therefore, organizations should schedule remediation to mitigate any risks associated with this vulnerability.
The availability impact is rated as low, indicating that while the service may be disrupted, it is not entirely compromised. Organizations should assess their exposure to this vulnerability and consider implementing controls to limit potential exploitation.
Given that the vulnerability is still awaiting analysis, organizations should remain vigilant and monitor for updates or patches that may be released by vendors or security advisories.
Vulnerability Details
CVE-2024-45338 describes a vulnerability in which crafted input can lead to non-linear parsing, resulting in denial of service. The CVSS score of 5.3 indicates a medium severity level, and the vulnerability falls under CWE-1333. The vulnerability was published on December 18, 2024, and is categorized as having a low attack complexity, requiring no privileges or user interaction.
Technical Analysis
The root cause of this vulnerability lies in how the Parse functions handle input. The non-linear processing of input length can lead to significant performance degradation. As the attack vector is classified as network-based, attackers can exploit this vulnerability remotely. The attack complexity is low, meaning that the required conditions for exploitation are straightforward. No privileges are required to trigger this vulnerability, and user interaction is not necessary.
The impacts on confidentiality and integrity are nonexistent; however, the availability impact is rated as low due to the potential for denial of service. Therefore, organizations should take this vulnerability seriously, as it can lead to service disruptions.
Risk & Impact Analysis
Risk to organizations includes the potential for denial of service, which can disrupt operations and affect user experience adversely. The low availability impact suggests that while services may slow down, they will not be completely unavailable. Organizations should assess their infrastructure and determine the potential blast radius of this vulnerability, especially in high-traffic environments where performance is critical.
Given the CVSS score of 5.3, organizations should address this vulnerability in their priority patch cycle. Regular monitoring for updates and effective incident response strategies can help mitigate the risks associated with this vulnerability.
