A vulnerability was found in Acrel Electrical EEMS Enterprise Power Operation and Maintenance Cloud Platform 1.3.0. This vulnerability allows an attacker to manipulate the argument File within the file /SubstationWEBV2/main/uploadH5Files, resulting in unrestricted file uploads. The attack may be executed remotely, which raises significant risks for organizations leveraging this platform. Given that the exploit has been made public, the urgency for defenders to take action is paramount.
The CVSS score of 2.1 classifies this vulnerability as low severity. However, it is critical to understand that the potential for exploitation exists, especially since the vendor was contacted early regarding this disclosure but did not respond. Organizations using this platform should prioritize patching immediately.
Risk to organizations includes unauthorized access to sensitive data and potential further exploitation within the network. Mitigation steps must be taken without delay to prevent any possible breaches or data loss.
In light of these risks, organizations should assess their exposure and take immediate action to remediate this vulnerability.
Vulnerability Details
The vulnerability detailed in CVE-2026-7696 affects the Acrel Electrical EEMS Enterprise Power Operation and Maintenance Cloud Platform version 1.3.0. The specific function impacted is the file upload feature located at /SubstationWEBV2/main/uploadH5Files. The unrestricted upload capability allows attackers to potentially upload malicious files, compromising the system's integrity.
The vulnerability has been classified under CWE-284 (Improper Access Control) and CWE-434 (Unrestricted Upload of File with Dangerous Type). The CVSS version 3.1 score is 6.3, indicating medium severity, while the CVSS version 4.0 score is 2.1, categorized as low severity. The vulnerability was published on May 3, 2026.
Technical Analysis
The root cause of this vulnerability stems from insufficient validation of input files, allowing attackers to exploit the file upload feature. The attack vector is network-based, with low complexity. It requires low privileges and no user interaction, making it particularly dangerous. The confidentiality, integrity, and availability impacts are all classified as low, yet the potential for misuse remains.
Organizations using this platform should implement strict controls on file uploads and ensure that proper validation checks are in place to mitigate this risk.
Risk & Impact Analysis
The real-world risk associated with CVE-2026-7696 is primarily due to the unrestricted file upload capability. This could lead to remote code execution or unauthorized access to sensitive systems, which is a critical concern for any organization. The potential blast radius is significant, as an attacker could leverage this vulnerability to gain further access within the network.
Organizations should assess their current use of the Acrel platform and prioritize remediation efforts based on the CVSS score and the potential impact on their operations. The vulnerability's classification as low severity should not diminish the urgency, as the exploit has been made public.
