Summary

CVE-2023-7325 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Cn Sec (inferred from references). Its CVSS base score is 9.3 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique LSASS Memory (T1003.001); ranked at the 33th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

Vulnerability Data

Anheng Mingyu Operation and Maintenance Audit and Risk Control System up to 2023-08-10 contains a server-side request forgery (SSRF) vulnerability in the xmlrpc.sock handler. The product accepts specially crafted XML-RPC requests that can be used to instruct the server to…

more

connect to internal unix socket RPC endpoints and perform privileged XML-RPC methods. An attacker able to send such requests can invoke administrative RPC methods via the unix socket interface to create arbitrary user accounts on the system, resulting in account creation and potential takeover of the bastion host. VulnCheck has observed this vulnerability being exploited in the wild as of 2025-10-30 at 00:30:17.837319 UTC.

Mitigating Controls (NIST 800-53 r5) AI

Directly mandates unique identification and authentication of users before access to functions requiring identity.

Extends the same authentication requirement to non-organizational users accessing critical functionality.

Requires authentication of services before they can invoke or expose critical functions.

Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.

Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.

Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.

PR.AA-05 partial match

Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.

Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.
