CVE-2023-38170 is a high severity vulnerability identified in the Microsoft HEVC Video Extensions software. This vulnerability allows remote code execution due to improper validation of input. Given its CVSS score of 7.8, this vulnerability poses a significant threat to organizations utilizing the affected software. Organizations should prioritize patching immediately to mitigate the risk of exploitation.
The vulnerability was first published on August 8, 2023, and has since been modified. As the vulnerability is classified as high severity, it is essential for organizations to remain vigilant and address this issue without delay to prevent potential security breaches.
Risk to organizations includes unauthorized access and execution of malicious code, which could lead to data breaches and further compromise of system integrity. As the vulnerability requires user interaction, the potential for exploitation increases if users are not aware of the risks associated with the software.
Currently, there are no known exploits or public proofs of concept available for CVE-2023-38170, but organizations should not become complacent. The nature of this vulnerability suggests that attackers could develop exploits if they are not addressed promptly.
Vulnerability Details
The official description for CVE-2023-38170 indicates that it is a remote code execution vulnerability in the Microsoft HEVC Video Extensions. This vulnerability is categorized under CWE-122, which pertains to improper input validation.
The CVSS score of 7.8 indicates a high severity level, with impacts on confidentiality, integrity, and availability. The attack vector is classified as local, requiring low attack complexity, no privileges, but user interaction is necessary to exploit the vulnerability.
The affected product is the Microsoft HEVC Video Extensions, with all versions prior to 2.0.61933.0 being vulnerable. The publication date for this vulnerability was August 8, 2023.
Technical Analysis
The root cause of CVE-2023-38170 stems from improper validation of input, which allows attackers to execute arbitrary code within the context of the user. This vulnerability is particularly concerning due to its potential impact on user data and system integrity.
The attack vector is local, meaning that an attacker would need physical or remote access to the vulnerable system to exploit the vulnerability. The attack complexity is low, indicating that the vulnerability can be exploited with minimal effort. Users are required to interact with the malicious content, which increases the risk of exploitation, especially in environments where users are less security-aware.
Successful exploitation could lead to high impacts on confidentiality, integrity, and availability, as the attacker could run arbitrary code, potentially gaining control over the affected system.
Risk & Impact Analysis
Organizations utilizing the Microsoft HEVC Video Extensions must recognize the significant risks associated with CVE-2023-38170. The potential for unauthorized access and execution of malicious code can lead to data breaches, loss of sensitive information, and disruption of services. The blast radius includes any system running the vulnerable software, which could be extensive in enterprise environments.
The urgency for organizations to patch this vulnerability is high, given its CVSS score of 7.8 and the potential impacts on confidentiality, integrity, and availability. Organizations should address this vulnerability in their priority patch cycle to mitigate risks effectively.
