A vulnerability was determined in Acrel Electrical EEMS Enterprise Power Operation and Maintenance Cloud Platform 1.3.0. Affected by this issue is some unknown functionality of the file /SubstationWEBV2/app/..;/main/upfile. Executing a manipulation of the argument path can lead to path traversal. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
Casky was already ahead
This CVE exploits attack patterns that Casky's 331matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.
CVE-2026-9550 exploits a path traversal vulnerability in Acrel Electrical's EEMS Enterprise Power Operation and Maintenance Cloud Platform version 1.3.0. The vulnerability exists in the file upload functionality at /SubstationWEBV2/app/..;/main/upfile, where insufficient input validation on the 'path' parameter allows attackers to traverse directory structures and write files outside intended directories. This impacts critical infrastructure operators relying on Acrel's power management systems, enabling unauthorized file placement that could compromise system integrity, introduce malicious code, or expose sensitive configuration data. The lack of vendor response and public disclosure increase the risk of widespread exploitation.
Casky.ai's 754 mapped security skills leverage Claude's extended reasoning to detect the attack patterns underlying this vulnerability across MITRE ATT&CK techniques TA0001 (Initial Access) and TA0007 (Discovery). Practitioners using Casky would identify abnormal file upload requests with suspicious path parameters containing traversal sequences (../, ..\ or URL-encoded variants), coupled with unexpected file creation in system directories. The platform's skill set would flag reconnaissance activity probing the /SubstationWEBV2 endpoint structure, anomalous file system writes outside designated upload folders, and attempts to access parent directories during upload operations—enabling detection of both pre-exploitation reconnaissance and active compromise attempts before attackers establish persistence in power infrastructure environments.
