Enterphone MESH - Hardcoded Credentials (CVE-2025-26793)

CVE-2025-26793 is a security vulnerability in the Hirsch Enterphone MESH system, where the web GUI configuration panel is shipped with hardcoded default credentials that are not required to be changed during setup. This oversight allows attackers to remotely access the administration interface via the Internet, potentially compromising the security of numerous apartment buildings and exposing residents' personally identifiable information (PII). The risk is heightened by the complexity involved in changing these default credentials, making it easier for threat actors to exploit the flaw for unauthorized access and data theft.

CrowdSec has been tracking this vulnerability and its exploits since 12th of June 2025.

According to CrowdSec data, while opportunistic exploitation dominates, a portion of threat actors trying to exploit CVE-2025-26793 apply basic targeting methods such as port or service detection. This indicates emerging patterns of selective targeting. In addition, according to the CrowdSec network, attack volume against CVE-2025-26793 has dipped slightly compared to the previous week. Although still commonly targeted, the decline suggests a cooling-off period. Long-term relevance remains, but attention is waning.

Attackers exploit the default credentials by sending POST requests to the FREEDOM Administration login endpoint, targeting /mesh/servlet/mesh.webadmin.MESHAdminServlet?requestedAction=login to gain unauthorized administrative access.
