CVE-2011-3269
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 · uneditedLexmark X, W, T, E, C, 6500e, and 25xxN devices before 2011-11-15 allow attackers to obtain sensitive information via a hidden email address in a Scan To Email shortcut.
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 confidenceThis is an information disclosure vulnerability in multiple Lexmark printer models (X, W, T, E, C, 6500e, and 25xxN) where a hidden email address embedded in Scan To Email shortcuts can be extracted by unauthenticated attackers, potentially revealing sensitive configuration or administrative information.

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 Lexmark printer modelCheck the device model label or access the printer's web interface or control panel to confirm the exact model number (X950, X952, X954, X940e, X945e, X925de, X860, or X862).Affected if The model is one of the eight affected models listed in the CVE.
-
Determine the installed firmware versionAccess the printer's embedded web server (EWS) via its IP address, navigate to the Support or Diagnostics section, and locate the firmware version information. Alternatively, print a configuration or settings page from the control panel.Affected if The firmware version string is at or below the affected threshold for your specific model (e.g., lhs1.tq.p145h for X950/X952/X954, lc.br.p051hds for X940e/X945e, lhs1.hk.p136l for X925de, or lp.sp.p510b for X860/X862).
-
Verify if Scan To Email feature is configuredAccess the printer's EWS and navigate to the Scan To Email settings section, or check the email/shortcut configuration through the printer's control panel menu under Scan or Email settings.Affected if Scan To Email is enabled and contains configured email shortcuts or addresses.
-
Confirm network accessibility of the vulnerabilityVerify that the printer's web interface (HTTP/HTTPS ports) is accessible from network segments where unauthenticated users could send requests. Check for any IP filtering or access control lists applied to the device.Affected if The printer's management interface is reachable from untrusted network segments without authentication.
You are affected if you have a listed Lexmark model running firmware at or below the specified version threshold AND the Scan To Email feature is configured, with the device accessible to unauthenticated network users.

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 dataApply the vendor firmware update released on or after 2011-11-15. If immediate patching is not feasible, disable the Scan To Email feature and isolate affected devices on a restricted network segment.
