What is CVE-2025-21298?

CVE-2025-21298 is a remote code execution vulnerability affecting various Microsoft products through Windows Object Linking and Embedding (OLE). This flaw allows attackers to execute arbitrary code on an affected system, potentially leading to unauthorized control and significant disruptions within an organization's IT infrastructure. The inherent risk of this vulnerability necessitates immediate attention from organizations utilizing Microsoft software, as it opens the door for serious security breaches.

Technical Details

This vulnerability is categorized under remote code execution, meaning that successful exploitation can occur without prior authentication by the attacker. Attackers may exploit this flaw through specially crafted files or web links that interface with the OLE framework. This can trigger malicious code execution in the context of the user’s session, thereby compromising the security of the impacted systems. Given the scope of Microsoft products that utilize OLE, the breadth of potential targets is extensive.

Potential Impact of CVE-2025-21298

  1. Unauthorized System Control: Exploitation of this vulnerability may allow attackers to gain complete control over affected systems, enabling them to execute arbitrary commands and manipulate data without detection.

  2. Data Breach Risks: The remote code execution capability could facilitate unauthorized access to sensitive information, leading to potential data breaches that can have severe legal and financial repercussions for organizations.

  3. Disruption of Business Operations: Malicious exploitation could result in significant operational disruption, including downtime, data loss, and the potential need for costly recovery measures, ultimately impacting an organization’s productivity and reputation.

Affected Version(s)

Windows 10 Version 1507 32-bit Systems 10.0.10240.0 < 10.0.10240.20890

Windows 10 Version 1607 32-bit Systems 10.0.14393.0 < 10.0.14393.7699

Windows 10 Version 1809 32-bit Systems 10.0.17763.0 < 10.0.17763.6775

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
