Detailsinfo

A vulnerability classified as problematic was found in Orca Energy Heat Pump and User Portal (affected version not known). This vulnerability affects some unknown functionality of the component HTTP Connection Handler. The manipulation with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. As an impact it is known to affect integrity. CVE summarizes:

Missing authentication and clear‑text transmission of data from the heat pumps to the control server, combined with the absence of input validation on aggregated data, can lead to stored XSS that enables theft of cookies from the pump’s web control interface. Older Orca heat pump devices communicating with the Orca server over an unencrypted and unauthenticated HTTP connection on a non-secure port specifically enable an attacker to impersonate a legitimate device and inject malicious payloads. This enables the insertion of harmful code directly into the Orca user portal, potentially compromising user accounts, exposing sensitive information, and allowing further unauthorized actions within the portal.

The weakness was disclosed by Tom Kern. The advisory is available at cert.si. This vulnerability was named CVE-2026-25599 since 02/03/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1059.007 by the MITRE ATT&CK project.
