Analyst readout for executives and security teams
Plain-English summary
CVE-2026-9523 is a high-severity SQL injection issue in Acrel Electrical EEMS 3000WEBV2. A remote attacker may be able to affect database confidentiality, integrity, and availability through a vulnerable request parameter. Public exploit material is reported, but active exploitation is not confirmed in the supplied sources.
Executive priority
Prioritize discovery and exposure reduction now. The affected platform is tied to power operations, the bug is remotely reachable without authentication, and public exploit material is reported. No confirmed patch is identified in the supplied evidence.
Technical view
The vulnerability affects an unknown function behind /SubstationWEBV2/app/..;/calc/getCalcmeterDetailDayListTree. Manipulating the sort argument can trigger SQL injection. The record lists network access, low complexity, no authentication, CVSS v2 7.5, CWE-74, and CWE-89. No vendor response or fixed version is named.
Likely exposure
Exposure is limited to organizations running Acrel Electrical EEMS Enterprise Power Operation and Maintenance Cloud Platform 3000WEBV2. Risk rises sharply if the platform is reachable from the internet or broadly accessible from operational networks.
Exploitation context
The source bundle says exploit material is public and may be used. It does not show CISA KEV listing or confirmed in-the-wild exploitation. Treat this as credible near-term risk because the issue is remote, unauthenticated, and affects a power operations platform.
Researcher notes
Evidence is primarily from CVE/VulDB records and a third-party submission. The affected function is described as unknown, and the vendor reportedly did not respond. Do not assume fixed builds, exploit prevalence, or safe configuration defaults from the supplied sources.
Mitigation direction
- Identify any deployed Acrel EEMS 3000WEBV2 instances.
- Check Acrel or integrator guidance for patches or supported mitigations.
- Restrict platform access to trusted networks and administrators only.
- Place compensating controls in front of exposed instances where removal is not possible.
- Increase monitoring for suspicious access to the affected calc route.
Validation and detection
- Confirm product name and version on all Acrel EEMS deployments.
- Determine whether affected instances are internet reachable or broadly reachable internally.
- Review web access logs for requests to the named calc route.
- Look for unusual sort parameter activity without testing exploit payloads.
- Track CVE and VulDB updates for vendor response or revised severity.

CWE-74: Exact CWE lookup
Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupCWE-89: Database access and collection lookup
Injection into data stores can inform collection, data access, and exfiltration detection reviews. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupDatabase behavior lookup
The CVE wording references database injection or access, so collection and exfiltration review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
