CVE-2018-5924
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 · uneditedA security vulnerability has been identified with certain HP Inkjet printers. A maliciously crafted file sent to an affected device can cause a stack buffer overflow, which could allow remote code execution.
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 confidenceA stack buffer overflow vulnerability in HP Inkjet printers allows remote code execution when a maliciously crafted file is sent to the affected device. The overflow occurs during file processing, potentially allowing an attacker to execute arbitrary code.

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 HP printer modelCheck the printer's control panel display, or access the embedded web server by entering the printer's IP address in a browser, or query the device via SNMP (community string public) using snmpwalk on OID 1.3.6.1.2.1.1.2Affected if The printer model matches one of: T8x44, 3aw51a, A9u28b, D3a82a, V1n08a, Y5h80a, D4h24b, or F5s57a
-
Retrieve the installed firmware versionAccess the printer's embedded web server (EWS) via HTTP using the IP address, navigate to the 'Information' or 'General' page to view the firmware version, or print a configuration/status page from the printer control panelAffected if The displayed firmware version matches exactly one of: 1828a, 1828b, 1826a, or 1829a
-
Confirm the printer accepts network print jobsVerify the printer has network printing services enabled (TCP/IP printing, IPP, or JetDirect). Check the EWS 'Networking' or 'Services' tab, or attempt to connect to common print ports (TCP 9100, 631, 80) using telnet or netcatAffected if The printer is reachable on the network and listening on print service ports (9100, 631, 80)
-
Verify file processing capability is activeConfirm that the printer's embedded web server has an 'Upload' or 'File Upload' feature enabled, or verify that the device accepts file uploads via Web Services (WS-Discovery, WS-Print), or check if the printer supports direct file submissionAffected if The printer accepts file uploads or processes submitted documents through network interfaces
The device is affected if it is an HP Inkjet printer model T8x44, 3aw51a, A9u28b, D3a82a, V1n08a, Y5h80a, D4h24b, or F5s57a running firmware version 1828a, 1828b, 1826a, or 1829a and is network-accessible with print or file upload services enabled.

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 available firmware updates from HP, network segment printer devices, and implement input validation on print jobs if possible.
