CVE-2023-24033 is a high-severity vulnerability affecting the Samsung Exynos Modem 5123, Exynos Modem 5300, Exynos 980, Exynos 1080, and Exynos Auto T512 baseband modem chipsets. This vulnerability allows the exploitation of improper checks on format types specified by the Session Description Protocol (SDP) module. As a result, attackers can trigger a denial of service (DoS) condition, impacting device functionality.
The severity of this vulnerability is classified as high, with a CVSS score of 7.5, indicating serious implications for affected devices. Organizations utilizing these chipsets must assess their exposure and the potential impact on their operations. The risk to organizations includes service disruption, which can lead to significant operational and reputational damage.
Currently, there is no public knowledge of exploits or proofs of concept for this vulnerability. However, the nature of the issue suggests that it may be actively sought by attackers. Organizations should prioritize patching immediately to mitigate any risks associated with this vulnerability.
Given the critical nature of the vulnerabilities identified, it is advisable for organizations to remain vigilant and proactive in their security posture, especially regarding firmware updates and vulnerability management processes.
Vulnerability Details
The official description for CVE-2023-24033 indicates that the affected Samsung Exynos Modem chipsets do not properly check format types specified by the SDP module. This could lead to a denial of service, allowing unauthorized access to device functionality. The CVSS score of 7.5 reflects a high severity, while the NVD has classified it as critical with a score of 9.8 due to the potential impacts on confidentiality, integrity, and availability.
The affected products include the Exynos Modem 5123, Exynos Modem 5300, Exynos 980, Exynos 1080, and Exynos Auto T512 firmware versions. The vulnerability was published on March 13, 2023, and has been classified under CWE-20, indicating improper input validation as the root cause.
Technical Analysis
The root cause of this vulnerability lies in the failure of the affected chipsets to properly validate the format types specified by the SDP module. The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely without physical access to the device. The attack complexity is low, requiring no special privileges or user interaction, which further facilitates potential exploitation. The consequences of a successful attack include a complete denial of service, affecting the availability of the device.
Given the lack of required privileges and user interaction, this vulnerability poses a significant threat to devices utilizing these Samsung chipsets. Organizations must focus on ensuring that their systems are configured to reject malformed SDP inputs, thus preventing potential service disruption.
Risk & Impact Analysis
Organizations utilizing the affected Samsung Exynos chipsets must recognize the real-world deployment risks associated with CVE-2023-24033. The risk to organizations includes service disruption due to denial of service, which can impact critical operations and lead to financial losses. With the vulnerability having a high exploitability score, there is an urgent need for organizations to address this vulnerability in their patch management cycles.
The potential blast radius of an exploit is significant, as many devices may rely on these chipsets for network connectivity. Organizations must prioritize remediation efforts based on the high CVSS score associated with this vulnerability, assessing their exposure and implementing necessary updates.
