CVE-2015-7261
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 · uneditedThe FTP service in QNAP iArtist Lite before 1.4.54, as distributed with QNAP Signage Station before 2.0.1, has hardcoded credentials, which makes it easier for remote attackers to obtain access via a session on TCP port 21.
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 FTP service in QNAP iArtist Lite before version 1.4.54 and QNAP Signing Station before version 2.0.1 contains hardcoded credentials embedded in the software. Attackers can exploit this by connecting to TCP port 21 using these known credentials to gain unauthorized remote access to the affected systems.

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 installed QNAP application and versionCheck the installed programs or application metadata for QNAP iArtist Lite or QNAP Signage Station and note the exact version numberAffected if Version is iArtist Lite <= 1.4.53.1 or Signage Station <= 2.0
-
Verify FTP service is enabledCheck system services or application settings to determine if the FTP service daemon is running or configured to startAffected if FTP service is active or set to auto-start on the system
-
Confirm FTP port accessibilityCheck if TCP port 21 is listening on the system using netstat, ss, or similar network utilityAffected if Port 21 is open and accepting connections from the network
The system is affected if a vulnerable version of iArtist Lite (1.4.53.1 or earlier) or Signage Station (2.0 or earlier) is installed AND the FTP service is enabled and accessible on port 21.
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 · scopedUpdate iArtist Lite to version 1.4.54 or later and Signage Station to version 2.0.1 or later. If updates cannot be applied immediately, disable the FTP service or restrict network access to port 21 at the firewall level.
iArtist Lite: 1.4.54 or later; Signage Station: 2.0.1 or later
- 1. Identify the currently installed version of QNAP iArtist Lite or Signage Station by checking the application or system settings
- 2. For iArtist Lite: Download and install version 1.4.54 or later from the official QNAP website or app repository
- 3. For Signage Station: Download and install version 2.0.1 or later from the official QNAP website or app repository
- 4. After upgrading, immediately change any FTP passwords from default values to strong, unique passwords
- 5. Verify the installed version reflects the patched release
- 6. If FTP service is not required, consider disabling it to reduce attack surface
