This vulnerability allows a local attacker to execute arbitrary code via the Ap4RtpAtom.cpp during the execution of mp4fragment with a crafted MP4 input file. The vulnerability has a CVSS score of 7.3, indicating a high severity level, which should be taken seriously by organizations using affected versions of Bento4.
Risk to organizations includes potential unauthorized code execution, which can lead to severe impacts such as data breaches or system compromise. Given the exploitability of this vulnerability, organizations should prioritize patching immediately.
As of now, there is no confirmed public exploit available, but the nature of this vulnerability underscores the importance of immediate action. The vulnerability was published on February 19, 2025, and affects Bento4 version 1.6.0-641.
Organizations should assess their usage of Bento4 and apply any available patches as soon as possible to mitigate this risk.
Vulnerability Details
The buffer overflow vulnerability affects Bento4 v.1.6.0-641, allowing local attackers to execute arbitrary code. The official CVE description states that the vulnerability occurs specifically in the AP4_RtpAtom::AP4_RtpAtom function.
The CVSS score of 7.3 indicates that this is a high-severity vulnerability, characterized by a local attack vector, low attack complexity, and the requirement of low privileges and user interaction. The impacts on confidentiality, integrity, and availability are all high.
The vulnerability falls under the CWE classification CWE-94, which relates to code execution vulnerabilities.
Technical Analysis
The root cause of this vulnerability is a buffer overflow condition that occurs when processing crafted MP4 input files. Attackers may leverage this vulnerability by providing specially crafted inputs that exceed the buffer limits, leading to arbitrary code execution.
The attack vector is local, meaning that an attacker must have access to the same system to exploit the vulnerability. The attack complexity is low, indicating that exploitation does not require advanced skills. Low privileges are required for exploitation, and user interaction is necessary since the crafted input must be processed by the application.
The vulnerability impacts confidentiality, integrity, and availability, all rated as high, indicating that successful exploitation could lead to significant consequences for affected systems.
Risk & Impact Analysis
Organizations using Bento4 v.1.6.0-641 face real-world risks due to the potential for arbitrary code execution. Attackers may exploit this vulnerability to gain control over affected systems, leading to unauthorized access to sensitive data or disruption of services.
The blast radius of this vulnerability can extend to any system where Bento4 is implemented, potentially impacting multiple users and applications. Given that the CVSS score is high and that there are no current protections against exploitation, this vulnerability should be addressed as a matter of urgency.
With an EPSS score indicating a median likelihood of exploitation, organizations should assess their risk posture and prioritize remediation efforts based on this vulnerability's potential impact.
