CISA KEV Advisory
Microsoft GDI Remote Code Execution Vulnerability
A remote code execution vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in the memory. An attacker who successfully exploited this vulnerability could take control of the affected system.
Apply updates per vendor instructions.
Risk Analysis
A remote code execution vulnerability exists in the Windows Graphics Device Interface (GDI) due to how it handles objects in memory. Successful exploitation could allow an attacker to take full control of the affected system. With a high EPSS score of 0.34444 and confirmed exploitation, this is a critical remote code execution vulnerability.
This vulnerability has been actively exploited in the wild and is listed in CISA's KEV catalog, indicating confirmed real-world exploitation. The flaw is remotely exploitable.
Apply the latest security updates from Microsoft to patch the Windows GDI component. Ensure all systems are running the most current versions of Windows.
Technical Analysis
CVE-2019-0903 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2019-0903 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
