Advantech WISE-IoTSuite/SaaS - SQL Injection

id: CVE-2025-52694

info:
  name: Advantech WISE-IoTSuite/SaaS - SQL Injection
  author: Loi Nguyen Thang
  severity: critical
  description: |
    Advantech WISE-IoTSuite/SaaS Composer suffers from an unauthenticated SQL Injection vulnerability due to the unsafe use of the `filename` parameter within the URL path in PostgreSQL queries. Remote attackers can exploit this flaw by injecting SQL code (such as the use of `pg_sleep` for time delays) to verify the vulnerability, and may gain further impact such as Remote Code Execution (RCE) depending on the privileges granted to the database user.
  impact: |
    Successful exploitation could allow an attacker to dump the database, modify data, or execute remote commands on the underlying server.
  remediation: |
    Apply the latest security patches provided by Advantech or sanitize the `filename` input parameter to prevent SQL injection.
