    How the Exploit Works

    The exploit works by a privileged user leveraging the insufficiencies in the granularity of access control in the OOB-MSM. This user could then exploit these weaknesses to escalate their privileges via adjacent access. Once the user has escalated their privileges, they could potentially compromise the system or leak sensitive data.

    Conceptual Example Code

    While the exact code that could exploit this vulnerability is unique to each specific system, the below pseudocode provides a high-level concept of how the exploit might work:

    function exploitVulnerability() {
    // Gain privileged user access
    let user = getPrivilegedUserAccess();
    // Exploit insufficiency in access control
    let escalatedPrivileges = exploitAccessControl(user);
    // If successful, compromise system or leak data
    if (escalatedPrivileges) {
    compromiseSystemOrLeakData();
    }
    }

    In this example, the exploit begins by gaining access as a privileged user. It then exploits the insufficiency in the granularity of access control to escalate privileges. If successful, the exploit culminates in the compromise of the system or leakage of data.
