CVE-2025-8286
Published: 31 July 2025
Summary
CVE-2025-8286 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Cisa (inferred from references). Its CVSS base score is 9.3 (Critical).
Operationally, ranked in the top 22.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability CVE-2025-8286 stems from missing authentication for a critical function (CWE-306) in affected products, which expose an unauthenticated Telnet-based command line interface. This flaw received a CVSS 4.0 score of 9.3 and permits unauthenticated network access to device functions that should be protected.
An attacker with network reachability can exploit the interface without credentials to modify hardware configurations, manipulate data, or issue a factory reset, resulting in high impact to confidentiality, integrity, and availability of the device.
The referenced CISA advisory ICSA-25-212-01 addresses the issue and outlines mitigation steps for affected deployments. Exploitation probability remains low, with an EPSS score that has ranged between 0.0104 and a peak of 0.0194.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
