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, exploitation aligns with the MITRE ATT&CK technique Services File Permissions Weakness (T1574.010); ranked in the top 37% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Mitigating Controls (NIST 800-53 r5) AI
Enforces approved authorizations on files and resources so overly permissive defaults cannot be exploited.
Requires least-privilege defaults so that installed files are not world-writable by default.
Requires documented, restrictive configuration settings that cover file and directory permissions.
Enforces access restrictions on changes, including permission settings applied during installation or configuration.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Hardened baselines and configuration management explicitly require correct default file permissions.
Defining and enforcing least-privilege access permissions directly prevents overly permissive defaults at install time.
Lifecycle management can encompass permission settings, yet the control is too broad to specifically mitigate incorrect defaults.
Secure SDLC practices include establishing secure defaults, but address only the development-phase portion of the weakness.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Standard templates that restrict access to utility programs and host parameter settings prevent the assignment of overly permissive default permissions on critical resources.
