CVE-2022-23771
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThis vulnerability occurs in user accounts creation and deleteion related pages of IPTIME NAS products. The vulnerability could be exploited by a lack of validation when a POST request is made to this page. An attacker can use this vulnerability to or delete user accounts, or to escalate arbitrary user privileges.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIPTIME NAS devices contain an insecure direct object reference or improper input validation vulnerability in the user account management pages. The affected endpoints for user creation and deletion do not properly validate POST requests, allowing unauthenticated or authenticated attackers to create new user accounts, delete existing accounts, or escalate privileges to administrator levels.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the IPTIME NAS modelAccess the device web interface or check the device label/management console to confirm the model is one of: Nas1dual, Nas2dual, or Nas4dualAffected if The device is an IPTIME Nas1dual, Nas2dual, or Nas4dual model
-
Check the installed firmware versionLog into the NAS web management interface and navigate to System Settings > Firmware Update, or check the admin page for firmware version information. Compare the version number to 1.4.86Affected if The firmware version is less than 1.4.86 (e.g., 1.4.85, 1.4.80, etc.)
-
Verify the web management interface is accessibleAttempt to access the NAS web interface over HTTP/HTTPS from the network where the device is deployedAffected if The user management web pages (typically under /user or /account management paths) are reachable on the network
-
Confirm user account management is exposedCheck if the web endpoints for user creation and deletion (such as /cgi-bin/user_mgmt or similar user management paths) are accessible without additional network restrictionsAffected if The user account management endpoints are accessible without proper network isolation or additional authentication layers
If the device is an IPTIME NAS1dual, NAS2dual, or NAS4dual running firmware version below 1.4.86 and the web management interface is network-accessible, the environment is affected by this vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.4.86
Apply vendor-provided patches for IPTIME NAS firmware. If no patch available, restrict network access to the NAS management interface and implement additional authentication layers at the network level.
IPTIME NAS Firmware 1.4.86 or later
- 1. Identify the specific IPTIME NAS model (Nas1dual, Nas2dual, or Nas4dual) in use
- 2. Access the NAS web management interface
- 3. Navigate to the firmware update or system settings section
- 4. Download the latest firmware version from the official IPTIME support website
- 5. Apply the firmware update following the vendor's instructions
- 6. Verify the update was successful and the firmware version shows 1.4.86 or later
- 7. After update, verify that CSRF protections are functioning by testing the user management functions
