Detection & IOCsextracted from sources · hover to see the quote
- →Exploit vector requires a user to open a specially crafted file; monitor for suspicious document opens triggering Windows Media processing (e.g., media-embedded Office documents or standalone media files opened by untrusted sources) ↗
- →Attack is network-delivered and requires user interaction; hunt for network-sourced file downloads followed by Windows Media component invocation (heap-based buffer overflow in Windows Media) ↗
- →This attack requires a user to open a specially crafted file from the attacker to initiate remote code execution; consider alerting on Windows Media parsing processes spawning unexpected child processes ↗

CVE-2025-29962 [HIGH] CWE-122 Windows Media Remote Code Execution Vulnerability
Windows Media Remote Code Execution Vulnerability
Description: Heap-based buffer overflow in Windows Media allows an unauthorized attacker to execute code over a network.
FAQ: How could an attacker exploit this vulnerability?
An unauthenticated attacker who successfully exploited this vulnerability could gain code execution through convincing a user to open a malicious document at which point the attacker could execute arbitrary code in the context of the user.
FAQ: According to the CVSS metric, the attack vector is network (AV:N) and user interaction is required (UI:R). What is the target context of the remote code execution?
This attack requires a user to open a specially crafted file from the attacker to initiate remote code execution.
