CVE-2019-1253
In short
A flaw in Windows AppX Deployment Server allows an attacker who already has access to a computer to gain higher privileges by exploiting how the system handles file system junctions. This lets them run code with administrator-level permissions without proper authorization.
Technical detail
An elevation of privilege vulnerability in Windows AppX Deployment Server stemming from improper junction handling (CWE-59) allows an authenticated local attacker to escalate privileges. The attack requires prior code execution on the target system and leverages symlink/junction manipulation to bypass security boundaries, resulting in execution with SYSTEM or elevated user context.
Summary generated and translated by AI from the official description.
An elevation of privilege vulnerability exists when the Windows AppX Deployment Server improperly handles junctions.To exploit this vulnerability, an attacker would first have to gain execution on the victim system, aka 'Windows Elevation of Privilege Vulnerability'. This CVE ID is unique from CVE-2019-1215, CVE-2019-1278, CVE-2019-1303.
