CVE-2024-20654

FAQ

According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?

Successful exploitation of this vulnerability simply requires the attacker or targeted user to leverage a Microsoft Access application to automatically talk to a SQL Server while utilizing a remote SQL Server address that they control.

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 ODBC, which could result in the client receiving a malicious networking packet. This could allow the attacker to execute code remotely on the client.

According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?

An authenticated victim who is connected to the network must be tricked or persuaded to connect to a malicious SQL database using their SQL client application. After the connection is made, the server can send specially crafted replies to the client that exploit the vulnerability and permit execution of arbitrary code within the context of the user's SQL client application.

According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?

An attacker could exploit the vulnerability by tricking an authenticated user (CVSS metric UI:R) into attempting to connect to a malicious SQL server via a connection driver (for example: ODBC and / or OLEDB as applicable).
