CISA KEV Advisory
Microsoft Windows Universal Plug and Play (UPnP) Service Privilege Escalation Vulnerability
A privilege escalation vulnerability exists when the Windows UPnP service improperly allows COM object creation.
Apply updates per vendor instructions.
Risk Analysis
This high-severity vulnerability in Windows UPnP service allows for privilege escalation due to improper COM object creation. An attacker can exploit this flaw to gain higher privileges on an affected system. The high EPSS score and inclusion in CISA's KEV confirm active exploitation and a high likelihood of further attacks.
This vulnerability is actively being exploited in the wild. Exploitation typically requires local access to the system to achieve privilege escalation.
Apply all available security updates for Microsoft Windows to address this vulnerability. Disable the UPnP service if it is not essential for operations.
Technical Analysis
CVE-2019-1405 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-2019-1405 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.
