The CVE-2025-25943 vulnerability is classified as a buffer overflow in Axiosys Bento4 version 1.6.0-641. This vulnerability allows a local attacker to execute arbitrary code via the AP4_Stz2Atom::AP4_Stz2Atom component located in Ap4Stz2Atom.cpp. The severity level is high, given the potential for unauthorized code execution and the implications it poses to system integrity.
The vulnerability has a CVSS score of 7.8, indicating a high severity level. The attack vector is local, and the attack complexity is low, meaning that an attacker with local access can exploit this vulnerability with relative ease. Organizations using the affected version should prioritize immediate remediation to mitigate risks.
Risk to organizations includes potential unauthorized access and control over affected systems, leading to data breaches or system compromise. Given the exploitation potential, immediate action is necessary to secure systems against this vulnerability.
The urgency for defenders is high, as local exploitation is possible. Organizations should prioritize patching immediately.
Vulnerability Details
The official CVE description identifies this vulnerability as a buffer overflow in the AP4_Stz2Atom component of Bento4 v.1.6.0-641. The CVSS score of 7.8 denotes a high severity, underscoring the critical nature of this vulnerability. The affected product is Bento4 by Axiosys, and it was published on February 19, 2025.
CWE-94 classification applies, indicating that this vulnerability falls under the category of improper control of generation of code ('Code Injection').
Technical Analysis
The root cause of this vulnerability is a buffer overflow in the AP4_Stz2Atom component, which may allow an attacker to overwrite the stack or heap memory. This can lead to arbitrary code execution if exploited.
The attack vector is local, meaning that an attacker must have local access to the system. The attack complexity is low, requiring minimal effort on the attacker’s part. Privileges required are low, indicating that standard user permissions are sufficient to exploit the vulnerability.
User interaction is not required for exploitation, and the potential impacts on confidentiality, integrity, and availability are all high, as arbitrary code execution could compromise the entire system.
Risk & Impact Analysis
Organizations using Bento4 v.1.6.0-641 are at significant risk due to this vulnerability. The potential for unauthorized code execution could lead to data breaches, loss of data integrity, and service disruptions. The blast radius is considerable, as an attacker could exploit this vulnerability across multiple systems if left unaddressed.
With a CVSS score of 7.8, the urgency for remediation is high. Organizations should prioritize patching this vulnerability as part of their security strategy, especially given that it is not actively exploited in the wild based on current intelligence.
