Hongjing e-HR before 8.2 contains a SQL injection vulnerability in the /servlet/codesettree endpoint where the categories query parameter is passed to a database query without sanitization after HRMS-encoding is stripped. An unauthenticated remote attacker can supply a crafted UNION SELECT payload to read arbitrary database content, including credential tables such as operuser. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-14.

Hongjing e-HR contains an unauthenticated SQL injection vulnerability in the getSdutyTree servlet endpoint that allows remote unauthenticated attackers to access protected resources by supplying a path traversal sequence in the request URI to bypass the oauthservlet authentication filter. Attackers can inject UNION-based SQL payloads through the unsanitized codeitemid parameter into the underlying Microsoft SQL Server query to retrieve sensitive database contents including user credentials. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-07-30 (UTC).
