Mingyu Operations and Maintenance Audit and…: Missing Authentication for Critical Functionality

Published Updated By the CyberSecBulletin desk

CVE-2023-7325 is a critical-severity missing authentication for critical functionality vulnerability in Mingyu Operations and Maintenance Audit and Risk Control System from Anheng Information (Hangzhou DBAPP Security Information Technology Co., Ltd.), with a CVSS 4.0 base score of 9.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 2023-08-10 as the first without the flaw, so updating Mingyu Operations and Maintenance Audit and Risk Control System to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.4% chance of exploitation within 30 days, which is low compared with other CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update Mingyu Operations and Maintenance Audit and Risk Control System to 2023-08-10 or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

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 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.

The underlying weakness: Missing Authentication for Critical Functionality

The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.

How developers prevent this class of flaw

  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator.
  • When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data.
