Summary

CVE-2025-4660 is a high-severity Incorrect Default Permissions (CWE-276) vulnerability in Forescout Secureconnector. Its CVSS base score is 8.7 (High).

Operationally, ranked in the top 18.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

A remote code execution vulnerability exists in the Windows agent component of SecureConnector due to improper access controls on a named pipe. The pipe is accessible to the Everyone group and does not restrict remote connections, allowing any network-based attacker to connect without authentication. This issue is tracked as CVE-2025-4660 with a CVSS score of 8.7 and is associated with CWE-276; it does not affect Linux or OSX versions of Secure Connector.

An unauthenticated network attacker can exploit the flaw by connecting to the exposed named pipe and redirecting the agent to communicate with a rogue server, which can then issue commands through the SecureConnector Agent to achieve remote code execution on the affected Windows system.

The EPSS score remains low and unchanged at 0.0152 with no material increase observed after disclosure.

addresses: CWE-276

Guides setting of default permissions to the minimum required level.

addresses: CWE-276

Establishes requirements for appropriate default permissions on system resources as part of configuration management.

addresses: CWE-276

Baseline establishment and updates on install/upgrade ensure correct default permissions rather than insecure ones.

addresses: CWE-276

Requiring the most restrictive settings instead of defaults prevents incorrect default permissions on resources.

addresses: CWE-276

Requires documented processes that include setting and maintaining correct default permissions for configuration items.

addresses: CWE-276

Requires addressing secure default permissions in physical and environmental protection controls.

addresses: CWE-276

Tailoring explicitly overrides or scopes default permission assignments in the baseline to match the system's actual risk and operational needs.
