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 · unedited
Sharp and Toshiba Tec MFPs improperly process URI data in HTTP PUT requests resulting in a path Traversal vulnerability. Unintended internal files may be retrieved when processing crafted HTTP requests.

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 confidence

Sharp and Toshiba Tec Multi-Function Printers (MFPs) contain a path traversal vulnerability in their web interface. Attackers can craft malicious URI data in HTTP PUT requests to access files outside the intended web root, potentially exposing sensitive internal documents or configuration files.

MitigationRestrict network access to MFP web management interfaces, apply vendor firmware updates when available, and consider placing MFPs in isolated network segments to reduce exposure.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm the MFP web interface is accessible
    Attempt to access the printer's web interface via HTTP (port 80/443) or HTTPS using the printer's IP address. If a login page or web console loads, the web interface is enabled.
    Affected if The web interface is enabled and reachable over the network - this is required for the path traversal attack to be exploitable.
  2. Identify the device model and firmware version
    Log into the web interface and navigate to the System Settings, Device Information, or Status page. Look for fields labeled 'Firmware Version', 'Model Name', or 'Device Name'. Alternatively, check the main landing page or footer for version information.
    Affected if The device model matches Sharp BP 70c45, 70c55, 70c65, 90c70, 90c80 or Toshiba Tec E Studio908, 1208, 1058, and the firmware version is at or below the affected thresholds.
  3. Compare installed firmware against affected versions
    For Toshiba Tec devices: note the exact firmware string (e.g., t1.01.h4.00 or t2.12.h3.00) and verify it is <= t1.01.h4.00 for E Studio1058/1208, or <= t2.12.h3.00 for E Studio908. For Sharp BP devices: all listed firmware versions (70c45, 70c55, 70c65, 90c70, 90c80) are affected regardless of version.
    Affected if The identified firmware version falls within or below the specified version ranges, or the device is a Sharp BP model listed as 'all versions' affected.
  4. Verify HTTP PUT method is allowed on the web server
    Send a test HTTP PUT request to the device's web interface (e.g., PUT /../../etc/passwd HTTP/1.1) using a tool like curl or Burp Suite. A response other than '405 Method Not Allowed' indicates PUT is accepted.
    Affected if The web server accepts PUT requests - this is the attack vector required to exploit the path traversal vulnerability.

Your environment is affected if the MFP has its web interface enabled, is network-accessible, and runs a firmware version matching the affected Sharp BP models (any version) or Toshiba Tec models at or below the specified version thresholds.
