CVE-2023-0620 | Vault Vulnerable to SQL Injection When Configuring the Microsoft SQL Database Storage Backend

HashiCorp Vault and Vault Enterprise versions 0.8.0 through 1.13.1 are vulnerable to an SQL injection attack when configuring the Microsoft SQL (MSSQL) Database Storage Backend. When configuring the MSSQL plugin through the local, certain parameters are not sanitized when passed to the user-provided MSSQL database. An attacker may modify these parameters to execute a malicious SQL command. This issue is fixed in versions 1.13.1, 1.12.5, and 1.11.9.

Base score Version Severity Vector Exploitability Impact Score source
6.5 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
