FAQ
What privileges could be gained by an attacker who successfully exploited this vulnerability?
An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.
According to the CVSS score, this vulnerability has Scope: Changed (S:C). What does this mean?
A CVSS Scope change (S:C) means that successful exploitation of this vulnerability allows an attacker to access resources outside the original security boundary of the vulnerable component. In this case, the vulnerable code runs within a restricted AppContainer environment, and exploitation could allow an attacker to access sensitive user data outside of that sandbox. Although this does not provide full system control, it represents a break out of the intended isolation boundary.
