#Security Vulnerability

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors might be helpful in your situation: The Windows message queuing service, which is a Windows component, needs to be enabled for a system to be exploitable by this vulnerability. This feature can be added via the Control Panel. You can check to see if there is a service running named **Message Queuing** and TCP port 1801 is listening on the machine.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is values of registry keys the attacker does not have permissions to view.

**According to the CVSS metric, privileges required is low (PR:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires the attacker must be an authenticated user on the network who is a member of the performance log users group. Although this group defaults to only Administrators, it is possible for an Administrator to add other standard users to this group.

**How could an attacker exploit this vulnerability?** An attacker could exploit the vulnerability by tricking an authenticated user into attempting to connect to a malicious SQL server via OLEDB, which could result in the server receiving a malicious networking packet. This could allow the attacker to execute code remotely on the client.

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is the contents of Kernel memory. An attacker could read the contents of Kernel memory from a user mode process.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** An attacker who successfully exploits this vulnerability could affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component could be different from the impacted component and are managed by different security authorities.

**What type of information could be disclosed by this vulnerability?** An attacker that successfully exploited this vulnerability could recover plaintext passwords and usernames from log files created by the affected CLI commands and published by Azure DevOps and/or GitHub Actions.

**How could an attacker exploit this vulnerability?** In a network-based attack, an authenticated attacker could execute code remotely within the SharePoint Server.
