CVE-2024-52963 is a low-severity vulnerability affecting Fortinet's FortiOS. This vulnerability allows an attacker to trigger a denial of service through specially crafted packets. The CVSS score for this vulnerability is 3.7, indicating a low level of severity. However, organizations should not overlook potential risks associated with denial-of-service conditions, as they can disrupt service availability.
The risk to organizations includes potential service interruptions that could affect business operations. Given its exploitability rating of low, organizations should plan to address this vulnerability in their upcoming patch cycles. It is critical that organizations remain vigilant and proactive in managing vulnerabilities, even those classified as low severity.
Currently, there is no known public exploit or proof of concept for this vulnerability. However, the potential for denial of service indicates that attackers may leverage this weakness if it remains unaddressed. Therefore, organizations should prioritize patching this vulnerability to maintain operational integrity.
Organizations should schedule remediation to mitigate the risk posed by CVE-2024-52963, particularly as Fortinet has provided versions that do not exhibit this vulnerability.
Vulnerability Details
This vulnerability allows for an out-of-bounds write in Fortinet FortiOS versions 7.6.0, 7.4.0 through 7.4.6, 7.2.0 through 7.2.10, 7.0.0 through 7.0.16, and 6.4.0 through 6.4.15. The official description indicates that this vulnerability can be exploited via specially crafted packets, resulting in a denial of service.
The CVSS 3.1 score of 3.7 reflects the low severity of this vulnerability, as it primarily affects availability (with an availability impact score of low). The vulnerability falls under the common weakness enumeration of CWE-787.
Organizations using FortiOS should be aware of the specific versions affected and ensure compliance with the latest updates provided by Fortinet.
Technical Analysis
The root cause of CVE-2024-52963 is an out-of-bounds write, which typically allows an attacker to overwrite memory regions that should not be modified. The attack vector is network-based, indicating that an attacker does not need physical access to the network to exploit this vulnerability.
The attack complexity is rated as high, meaning that the skill level required to exploit this vulnerability is significant. Additionally, no privileges are required for exploitation, nor is user interaction necessary. The confidentiality and integrity impacts are rated as none, while the availability impact is rated as low, indicating that the primary consequence of exploitation would be a temporary denial of service.
Risk & Impact Analysis
The risk of CVE-2024-52963 to organizations primarily involves potential service disruptions. In environments where Fortinet FortiOS is deployed, the impact of a denial of service can significantly affect operational capabilities.
Organizations should assess the potential blast radius of this vulnerability, particularly in critical infrastructure scenarios where FortiOS plays a key role in network security. Given the low CVSS score, the urgency for remediation is moderate; organizations should schedule remediation as part of their routine maintenance.
Despite the low severity rating, organizations should remain vigilant in monitoring for any exploitation attempts, as the landscape can evolve rapidly.
