Detection & IOCsextracted from sources · hover to see the quote
- →Attack vector requires a user to mount a specially crafted VHD file; monitor for VHD mount events on endpoints as a potential exploitation indicator. ↗
- →CVE-2025-24993 is confirmed actively exploited in the wild (Exploited:Yes, Exploitation Detected); prioritize detection of anomalous NTFS heap activity and VHD mount operations. ↗
- →The vulnerability is a heap-based buffer overflow in Windows NTFS triggered locally; monitor for unexpected code execution following VHD mount events, especially from unprivileged users. ↗
- →Zscaler Advanced Threat Protection subscription is flagged as required for coverage; ensure ATP policies are active for endpoints running affected Windows versions. ↗
- ·Despite the CVE title saying 'Remote Code Execution', the attack vector is local (AV:L); 'Remote' refers to the attacker's logical position, not network-based exploitation. The attack is carried out locally on the victim machine. ↗
- ·User interaction is required (UI:R); exploitation depends on tricking a local user into mounting a malicious VHD, meaning purely automated/network-based exploitation without user interaction is not applicable. ↗

CVE-2025-24993 [HIGH] CWE-122 Windows NTFS Remote Code Execution Vulnerability
Windows NTFS Remote Code Execution Vulnerability
Description: Heap-based buffer overflow in Windows NTFS allows an unauthorized attacker to execute code locally.
FAQ: According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?
The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.
FAQ: According to the CVSS metric, the attack vector is local (AV:L) while user interaction is required (UI:R). What does that mean for this vulnerability?
An attacker can trick a local user on a

Microsoft patches Windows Kernel zero-day exploited since 2023

CVE-2025-24983 [HIGH] Microsoft patches Windows Kernel zero-day exploited since 2023
## Microsoft patches Windows Kernel zero-day exploited since 2023
## Sergiu Gatlan
ESET said on Tuesday that a zero-day exploit targeting the CVE-2025-24983 vulnerability was "first seen in the wild" in March 2023 on systems backdoored using PipeMagic malware.
This exploit targets only older Windows versions (Windows Server 2012 R2 and Windows 8.1) that Microsoft no longer supports. However, the vulnerability also affects newer Windows versions, including the still-supported Windows Server 2016 and Windows 10 systems running Windows 10 build 1809 and earlier.
"The Use-After-Free (UAF) vulnerability is related to improper memory usage during software operation. This can lead to software crashes, execution of malicious code (including remotely), privilege escalation, or data corruption,"

CVE-2025-24991 [HIGH] Microsoft: 6 Zero-Days in March 2025 Patch Tuesday
Microsoft today issued more than 50 security updates for its various Windows operating systems, including fixes for a whopping six zero-day vulnerabilities that are already seeing active exploitation.
Two of the zero-day flaws include CVE-2025-24991 and CVE-2025-24993, both vulnerabilities in NTFS, the default file system for Windows and Windows Server. Both require the attacker to trick a target into mounting a malicious virtual hard disk. CVE-2025-24993 would lead to the possibility of local code execution, while CVE-2025-24991 could cause NTFS to disclose portions of memory.
Microsoft credits researchers at ESET with reporting the zero-day bug labeled CVE-2025-24983, an elevation of privilege vulnerability in older versions of Windows. ESET said the exploit was deployed via the PipeMa
