What is CVE-2023-54399?

The Hongjing e-HR software prior to version 8.2 is susceptible to a SQL injection vulnerability located at the /servlet/codesettree endpoint. This flaw allows an unauthenticated remote attacker to inject a crafted UNION SELECT statement through the categories query parameter, potentially exposing sensitive database contents, including user credentials. The issue arises from insufficient input sanitization once HRMS-encoding is removed. The infiltration method was first detected by the Shadowserver Foundation on October 14, 2023.
