CVE-2025-53131 is a high-severity Heap-based Buffer Overflow (CWE-122) vulnerability in Microsoft Windows 10 1809. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Malicious File (T1204.002); ranked in the top 46.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Requires timely remediation through vendor patches to eliminate the heap-based buffer overflow in Windows Media, preventing arbitrary code execution.
Enforces memory protections such as ASLR and DEP to block unauthorized code execution from heap buffer overflow exploits in Windows Media.
Deploys malicious code protection tools to scan for and prevent execution of malicious media files exploiting the Windows Media buffer overflow.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Heap buffer overflow in Windows Media enables RCE via opening a malicious file (user interaction required), directly facilitating T1204.002.
NVD Description
Heap-based buffer overflow in Windows Media allows an unauthorized attacker to execute code over a network.
Deeper analysisAI
CVE-2025-53131 is a heap-based buffer overflow vulnerability, classified under CWE-122, affecting the Windows Media component. Published on 2025-08-12T18:15:36.723, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.
An unauthorized attacker (PR:N) can exploit this vulnerability over the network (AV:N) with low attack complexity (AC:L), though it requires user interaction (UI:R), such as opening a malicious file. Successful exploitation allows arbitrary code execution in the context of the affected process, resulting in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H) without changing the scope (S:U).
