Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
An elevation of privilege vulnerability exists in the Windows AppX Deployment Service (AppXSVC) due to improper handling of hard links. The flaw is tracked under CWE-59 and carries a CVSS 3.1 base score of 7.8, reflecting local attack vector, low attack complexity, and low privileges required for exploitation. It affects Windows systems that use the AppX deployment mechanism and is distinct from the related CVE-2019-1130.
A local attacker with a low-privileged account can exploit the issue to obtain elevated privileges on the affected system, resulting in full control over confidentiality, integrity, and availability of the host. The attack requires no user interaction and can be performed from a standard user context.
Microsoft published remediation guidance in its security advisory for CVE-2019-1129. The vulnerability appears in CISA's catalog of known exploited vulnerabilities, confirming observed in-the-wild exploitation.
