The vulnerability resides in the /SubstationWEBV2/main/elecMaxMinAvgValue file, where manipulation of the fCircuitids argument allows for the injection of arbitrary SQL commands. The vulnerability, identified as CVE-2026-7694, can be exploited remotely without authentication, posing a significant risk to systems exposed to the network. The vendor was notified but did not respond, and a public exploit is available, increasing the likelihood of exploitation. This flaw allows attackers to potentially access, modify, or delete sensitive data within the ECEMS database.

Attack Chain

  1. Attacker identifies an accessible instance of Acrel ECEMS 1.3.0.
  2. Attacker crafts a malicious SQL payload designed to extract sensitive information or modify the database.
  3. The attacker sends a crafted HTTP request to /SubstationWEBV2/main/elecMaxMinAvgValue with the SQL payload embedded in the fCircuitids parameter.
  4. The ECEMS application fails to properly sanitize the fCircuitids input.
  5. The application executes the attacker-supplied SQL query against the database.
  6. The database server processes the malicious query, potentially returning sensitive data or executing harmful commands.
  7. The attacker receives the output of the injected SQL query.
  8. The attacker uses the extracted information for further malicious activities, such as data exfiltration, privilege escalation, or denial of service.

Impact

Successful exploitation of this SQL injection vulnerability could allow an attacker to read sensitive information from the ECEMS database, modify existing data, or even gain administrative access to the system. This could lead to the compromise of energy efficiency management data, potentially impacting grid stability and financial records. Given the lack of vendor response and the availability of a public exploit, organizations using the affected software are at high risk. The impact includes potential data breaches, system outages, and reputational damage.

Recommendation

  • Inspect web server logs for suspicious requests to /SubstationWEBV2/main/elecMaxMinAvgValue containing potentially malicious SQL syntax within the fCircuitids parameter (see Sigma rule “Detect Acrel ECEMS SQL Injection Attempt”).
  • Deploy the Sigma rule “Detect SQL Injection Error Messages” to identify potential SQL injection attempts across all web applications.
  • Apply input validation and sanitization to all user-supplied input, especially the fCircuitids parameter in /SubstationWEBV2/main/elecMaxMinAvgValue, to prevent SQL injection.
  • Consider deploying a web application firewall (WAF) to filter out malicious requests targeting this vulnerability.
