CVE-2023-46814 is a high-severity binary hijacking vulnerability affecting the VideoLAN VLC media player versions prior to 3.0.19 on Windows. This vulnerability allows standard users to execute arbitrary code with elevated privileges, specifically as SYSTEM, through the uninstaller that operates from a user-writable location. The potential for abuse is significant, making this a critical issue for organizations utilizing VLC.
The CVSS score of 7.8 indicates a high level of risk, primarily due to the ease of exploitation. Attackers with standard user access can leverage this vulnerability to execute code, leading to possible system compromise. Organizations should prioritize patching VLC media player installations to mitigate this risk.
Risk to organizations includes unauthorized access and potential data breaches, as the vulnerability can be exploited without user interaction. Given its nature, it is imperative for security teams to assess their environments for vulnerable installations and apply the necessary updates immediately.
Organizations should prioritize patching immediately.
Vulnerability Details
The official description states that a binary hijacking vulnerability exists within the VideoLAN VLC media player before version 3.0.19 on Windows. The uninstaller attempts to execute code with elevated privileges from a standard user writable location, enabling standard users to gain arbitrary code execution as SYSTEM.
The CVSS 3.1 score is 7.8, classified as high severity due to its potential impact on confidentiality, integrity, and availability, all rated as high. The vulnerability falls under CWE-427, indicating a binary hijacking risk. The vulnerability was made public on November 22, 2023.
Technical Analysis
The root cause of this vulnerability is improper handling of the uninstaller process that allows execution of arbitrary code with elevated privileges. The attack vector is local, requiring an attacker to have standard user access to the system. The attack complexity is low, as exploitation does not require significant skills or resources.
Privileges required are low, allowing any standard user to exploit this vulnerability. There is no user interaction required, making it easier for attackers to execute code without raising alarms. The potential impacts include high confidentiality, integrity, and availability risks, which could lead to complete system compromise.
Risk & Impact Analysis
Real-world deployment risk is substantial due to the wide usage of VLC media player across various environments. Exploitation could potentially allow attackers to elevate their privileges and execute malicious code, compromising sensitive data and system integrity. Organizations should consider the blast radius of this vulnerability, as it could affect multiple systems if exploited.
The urgency assessment based on the CVSS score indicates that this vulnerability should be addressed in the priority patch cycle. By mitigating this risk through immediate patching, organizations can protect their systems from unauthorized access and potential data leaks.
