Description

This security bulletin contains information about 3 vulnerabilities.


1) SQL injection (CVE-ID: CVE-2023-0620)

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data when using Vault’s community-supported Microsoft SQL (MSSQL) database storage backend. A remote user can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.


2) Input validation error (CVE-ID: CVE-2023-0665)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the PKI mount issuer endpoints do not correctly authorize access to remove an issuer or modify issuer metadata. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


3) Information disclosure (CVE-ID: CVE-2023-25000)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the Shamir implementation uses precomputed table lookups. A remote user can perform a cache-timing attack and recover the Shamir shares.
