Details
What privileges could be gained by an attacker who successfully exploited the vulnerability?
An attacker who successfully exploited this vulnerability would gain the ability to escape the AppContainer and impersonate a non-AppContainer token.
According to the CVSS metric, successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?
In this case, a successful attack could be performed from a low privilege AppContainer. The attacker could elevate their privileges and execute code or access resources at a higher integrity level than that of the AppContainer execution environment.
How could an attacker exploit this vulnerability?
An attacker could exploit the vulnerability by escaping the sensor-app docker container (which is running the web application) and running commands on the host. This would allow them to enter any other containers and potentially gain control over the system.
