CVE Number – CVE-2018-8339
A vulnerability in the Microsoft Windows Installer could allow a local attacker to escalate privileges on a targeted system.
The vulnerability is due to improper input sanitization by the affected software, which could cause the affected software to load insecure libraries. An attacker could exploit this vulnerability by accessing the system and executing an application that submits malicious input to the affected software. A successful exploit could allow the attacker to execute arbitrary code with system privileges and compromise the system completely.
Microsoft confirmed the vulnerability and released software updates.
To exploit this vulnerability, the attacker must have user-level access to the targeted system. This access requirement could reduce the likelihood of a successful exploit.
Microsoft addressed this vulnerability by correcting how the affected software sanitizes user-supplied input.
Administrators are advised to apply the appropriate updates.
