SQL Injection in risesoft-y9 WorkFlow-Engine

Publication date: 2026-09-29

Last updated on: 2026-09-29

Assigner: VulDB

Description
A vulnerability was detected in risesoft-y9 WorkFlow-Engine up to 9.6.10. Impacted is the function getByIdAndYear of the file CustomHistoricProcessServiceImpl.java of the component OAuth2 Resource Filter. Performing a manipulation of the argument year/processInstanceId results in sql injection. Remote exploitation of the attack is possible. The exploit is now public and may be used. The sink is injectable on two independent positions, not just one. The vendor was contacted early about this disclosure but did not respond in any way.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

CVE-2026-102616 is a SQL injection vulnerability in the risesoft-y9 WorkFlow-Engine up to version 9.6.10. The flaw exists in the getByIdAndYear function of CustomHistoricProcessServiceImpl.java within the OAuth2 Resource Filter component. Attackers can manipulate the year or processInstanceId arguments to inject malicious SQL code, enabling remote SQL injection attacks.

Detection Guidance
  • Check for unauthenticated access to /services/rest/historicProcess/getByIdAndYear endpoint by sending requests with manipulated year and processInstanceId parameters.
  • Monitor SQL query logs for suspicious patterns like direct string concatenation of user inputs in queries.
  • Use tools like SQLMap to test for blind SQL injection by sending boolean-based payloads (e.g., ' AND '1'='1' and ' AND '1'='2').
Impact Analysis

This vulnerability allows remote attackers to execute arbitrary SQL commands on the database without authentication. They can extract sensitive data like database versions, user credentials, or other confidential information. The attack can be automated to systematically guess and retrieve data character by character.

Compliance Impact

This vulnerability likely violates compliance requirements for GDPR and HIPAA due to unauthorized data access and potential data breaches. GDPR mandates protection of personal data, while HIPAA requires safeguarding protected health information. A successful exploit could lead to unauthorized data exposure, resulting in regulatory penalties and legal consequences.

Mitigation Strategies
  • Upgrade to a patched version of risesoft-y9 WorkFlow-Engine if available.
  • Implement strict authentication and authorization checks for all /services/rest/* endpoints.
  • Use parameterized queries instead of string concatenation to prevent SQL injection.
  • Restrict access to the processadmin front end and disable unauthenticated access to sensitive endpoints.
