CVSS v3.1
Official Description
Norton App Lock, prior to 1.4.0.503, may be susceptible to a bypass exploit. In this type of circumstance, the exploit can allow the user to circumvent the app to prevent it from locking other apps on the device, thereby allowing the individual to gain access.
Technical Analysis
CVE-2019-18373 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 5.6.
