Deeper analysis
CVE-2023-54340 is a SQL injection vulnerability (CWE-89) affecting WorkOrder CMS version 0.1.0. The flaw resides in the login functionality, where the username and password parameters are vulnerable to manipulation, enabling attackers to inject malicious SQL queries such as 'OR 1=1' or stacked queries. Published on 2026-01-13, it carries a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N), indicating high confidentiality impact with low attack complexity.
Unauthenticated remote attackers can exploit this vulnerability to bypass login authentication without user interaction. Successful exploitation allows extraction of sensitive database information or execution of administrative commands, potentially leading to unauthorized data access or control over the application.
