remote code execution under default configurations.
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates unrestricted file uploads by validating uploaded file types and content to block dangerous files from execution.
Restricts information inputs in the administrative interface to only safe file types, preventing upload of malicious executables.
Ensures timely remediation of the specific application flaw through vendor patching to version 8.14.9 or later.
Security SummaryAI
CVE-2025-57794 is an authenticated unrestricted file upload vulnerability in the administrative interface of Explorance Blue versions prior to 8.14.9. The application fails to adequately restrict uploaded file types, allowing malicious files to be uploaded and subsequently executed by the server. This flaw enables remote code execution under default configurations and carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H), mapped to CWE-434 (Unrestricted Upload of File with Dangerous Type).
Exploitation requires an authenticated user with high privileges, such as administrative access to the interface. A successful attack allows the upload of a malicious file that executes arbitrary code on the server, granting the attacker high-impact control over confidentiality, integrity, and availability, with a changed scope due to the server's execution context.
Vendor advisories from Explorance recommend updating to version 8.14.9 or later to mitigate the vulnerability.
