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
Several Ricoh printers have multiple buffer overflows parsing HTTP parameter settings for SNMP, which allow an attacker to cause a denial of service or code execution via crafted requests to the web server. Affected firmware versions depend on the printer models. One affected configuration is cpe:2.3:o:ricoh:sp_c250dn_firmware:-:*:*:*:*:*:*:* up to (including) 1.06 running on cpe:2.3:o:ricoh:sp_c250dn:-:*:*:*:*:*:*:*, cpe:2.3:o:ricoh:sp_c252dn:-:*:*:*:*:*:*:*. Another affected configuration is cpe:2.3:o:ricoh:sp_c250sf_firmware:-:*:*:*:*:*:*:* up to (including) 1.12 running on cpe:2.3:o:ricoh:sp_c250sf:-:*:*:*:*:*:*:*, cpe:2.3:o:ricoh:sp_c252sf:-:*:*:*:*:*:*:*.

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 confidence

Multiple buffer overflow vulnerabilities in Ricoh printer web servers allow remote attackers to cause denial of service or achieve code execution by sending crafted HTTP requests with malicious SNMP parameter settings. The vulnerabilities affect SP C250dn, SP C252dn, SP C250sf, and SP C252sf models running firmware versions up to 1.06 and 1.12 respectively.

MitigationApply vendor-released firmware updates to patch the buffer overflow vulnerabilities. If patches are unavailable, consider network segmentation to limit web server exposure and disable SNMP management interfaces if not required.

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. Identify the Ricoh printer model
    Access the printer web interface (HTTP/HTTPS) or check the device label/menu to confirm the exact model number is one of: SP C250dn, SP C252dn, SP C250sf, or SP C252sf
    Affected if The model is any of these four affected models
  2. Check the firmware version
    Log into the printer web interface and navigate to the System or Settings page to view the firmware version, or print a configuration page from the device menu
    Affected if Firmware version is below 1.13 for SP C250sf/SP C252sf, or below 1.07 for SP C250dn/SP C252dn
  3. Verify the web server is accessible
    Attempt to reach the printer IP address on HTTP (port 80) or HTTPS (port 443) from the network
    Affected if The web interface is reachable over the network
  4. Confirm SNMP management is available
    Access the web interface and check the SNMP or Network settings section to see if SNMP configuration options are present and enabled
    Affected if SNMP is enabled and configurable through the web interface

A user is affected if they have one of the four listed Ricoh printer models running firmware below the threshold (1.13 for sf models, 1.07 for dn models) with the web server and SNMP accessible on the 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.

dbcve · scoped
Upgrade available Upgrade to 1.07 / 1.13 or later
Fixed in 1.071.13
Interim mitigation

Apply vendor-released firmware updates to patch the buffer overflow vulnerabilities. If patches are unavailable, consider network segmentation to limit web server exposure and disable SNMP management interfaces if not required.

Recommended fix High confidence

Firmware 1.13 (for Sp C250sf/Sp C252sf) or Firmware 1.07 (for Sp C250dn/Sp C252dn)

  1. Identify the specific Ricoh printer model (Sp C250sf, Sp C252sf, Sp C250dn, or Sp C252dn) from the affected product list
  2. Download the appropriate firmware update from Ricoh's official support website (www.ricoh.com or www.ricoh-usa.com)
  3. For Sp C250sf and Sp C252sf models: Upgrade firmware to version 1.13 or later
  4. For Sp C250dn and Sp C252dn models: Upgrade firmware to version 1.07 or later
  5. Follow Ricoh's standard firmware update procedure, which typically involves uploading the firmware file through the printer's web administration interface or using Ricoh's firmware update utility
  6. After updating, verify the firmware version has been successfully applied
