Vulnerability details

A client-side remote code execution vulnerability exists in Hanwha Techwin Smart Security Manager (SSM) versions 1.32 and 1.4, due to improper restrictions on the PUT method exposed by the bundled Apache ActiveMQ instance (running on port 8161). An attacker can…

more

exploit this flaw through a Cross-Origin Resource Sharing (CORS) bypass combined with JavaScript-triggered file uploads to the web server, ultimately resulting in arbitrary code execution with SYSTEM privileges. This vulnerability bypasses the server-side mitigations introduced in ZDI-15-156 and ZDI-16-481 by shifting the exploitation to the client-side. This product is now referred to as Hanwha Wisenet SSM and it is unknown if current versions are affected.

Mitigating Controls

Likely Mitigating Controls AI

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.

addresses: CWE-306

Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.

addresses: CWE-306

Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.

addresses: CWE-306

Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.

addresses: CWE-306

Guarantees critical functions are protected by mandatory invocation of the access control mechanism.

addresses: CWE-306

Auditing sessions makes it possible to detect access to critical functions without required authentication.

addresses: CWE-306

The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.

addresses: CWE-306

Certification assesses that critical functions have required authentication controls in place.

addresses: CWE-306

Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
