CVE-2023-47359 is a critical vulnerability affecting Videolan's VLC Media Player, specifically versions prior to 3.0.20. This vulnerability allows for a heap-based buffer overflow due to an incorrect offset read in the function GetPacket(). The consequences of this flaw include memory corruption, which can lead to system instability and potential exploitation by malicious actors.
With a CVSS score of 9.8, this vulnerability is classified as critical, indicating its severe nature and potential impact. Risk to organizations includes unauthorized access to sensitive data, system crashes, and exploitation of the vulnerability through crafted network packets. Organizations should prioritize patching immediately to prevent exploitation.
Currently, there is no confirmed public exploit available for CVE-2023-47359, but the nature of the vulnerability makes it a significant risk, especially as it is identified as a network exploitable flaw with low attack complexity and no required user interaction.
Organizations using affected versions of VLC Media Player should take immediate action to apply the necessary patches or updates to mitigate the risk associated with this vulnerability.
Vulnerability Details
The vulnerability in question stems from an incorrect offset read in the GetPacket() function, which can lead to a heap-based buffer overflow. This is classified under CWE-787. The affected product is the VLC Media Player developed by Videolan, with the vulnerability impacting all versions prior to 3.0.20.
The vulnerability was published on November 7, 2023, and is currently marked as modified. Organizations should be aware that this flaw poses a high risk due to its potential for exploitation, and immediate remediation steps should be undertaken.
Technical Analysis
The root cause of CVE-2023-47359 lies in the incorrect handling of data offsets within the VLC Media Player's GetPacket() function, leading to a heap-based buffer overflow. This vulnerability can be exploited over the network (attack vector), requires no privileges (privileges required), and does not necessitate user interaction.
The attack complexity is assessed as low, which means that an attacker with basic skills can exploit this vulnerability without significant barriers. The impacts on confidentiality, integrity, and availability are all rated as high, indicating that successful exploitation could lead to significant consequences for affected systems.
Risk & Impact Analysis
Real-world deployment of VLC Media Player with this vulnerability presents significant risks to organizations. The possibility of memory corruption could lead to unauthorized access and manipulation of sensitive data. As the attack vector is network-based, the blast radius of exploitation could be extensive, potentially affecting multiple users and systems.
Given the CVSS score of 9.8, organizations should prioritize remediation efforts in their patch management cycles. The urgency for addressing this vulnerability is critical, and failure to act promptly could result in severe operational disruptions and data breaches.
