CVE-2020-15055
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 · uneditedTP-Link USB Network Server TL-PS310U devices before 2.079.000.t0210 allow an attacker on the same network to bypass authentication via a web-administration request that lacks a password parameter.
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 · high confidenceThe TP-Link TL-PS310U USB Network Server has an authentication bypass vulnerability in its web administration interface. Attackers on the same local network can bypass authentication by submitting a web request that omits the password parameter entirely, allowing unauthorized access to the device's admin functions.

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.
-
Confirm device modelIdentify the device on your network by checking its IP address, MAC OUI (TP-Link vendor prefix), or by accessing the web interface and checking the device model displayed in the admin page header or status sectionAffected if Device is not a TP-Link TL-PS310U unit - this vulnerability only affects this specific model
-
Check firmware versionAccess the web administration interface and navigate to the System or Firmware Upgrade section to view the current firmware version. Alternatively, check the device status page or any diagnostic output that displays the installed firmware build numberAffected if Firmware version is lower than 2.079.000.t0210 (any build below this version number)
-
Verify web administration interface accessibilityAttempt to access the device web admin interface over HTTP/HTTPS from your local network. Confirm the login page loads and accepts authentication attemptsAffected if Web administration interface is accessible from network segments accessible to untrusted users - the vulnerability allows bypass when the interface is exposed
-
Confirm vulnerable authentication mechanismReview the login form on the web administration interface. Note whether the form includes a password parameter in the HTML source or network request when submitting credentialsAffected if The login form submits a password parameter - the vulnerability exploits requests where this parameter is omitted entirely
You are affected if you have a TP-Link TL-PS310U device running firmware version below 2.079.000.t0210 with its web administration interface accessible from your network

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.
From vendor data2.079.000.t0210
Upgrade the device firmware to version 2.079.000.t0210 or later to resolve the authentication bypass. If firmware updates are unavailable, restrict access to the web administration interface using network segmentation, firewall rules, or disabling remote administration.
