CVE-2014-7888
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 OLE Point of Sale (OPOS) drivers before 1.13.003 on HP Point of Sale Windows PCs allow remote attackers to execute arbitrary code via vectors involving OPOSMICR.ocx for PUSB Thermal Receipt printers, SerialUSB Thermal Receipt printers, Hybrid POS printers with MICR, Value PUSB Receipt printers, and Value Serial/USB Receipt printers, aka ZDI-CAN-2512.
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 confidenceHP OPOS (OLE Point of Sale) drivers before version 1.13.003 contain a critical vulnerability in the OPOSMICR.ocx ActiveX control used across multiple thermal receipt printer models. Remote attackers can exploit this to execute arbitrary code, likely through malformed input handling in the MICR (Magnetic Ink Character Recognition) control component.

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.
-
Locate HP OPOS driver installationSearch the system for OPOSMICR.ocx file (typically found in C:\Windows\System32\ or C:\Windows\SysWOW64\ on 32-bit and 64-bit Windows respectively). Right-click the file, select Properties, and check the Version tab for the product version.Affected if The file version is 1.13.001 or lower, or the file exists but no version information is visible.
-
Check OPOSMICR.ocx file version directlyOpen a command prompt and run: dir C:\Windows\System32\OPOSMICR.ocx /s (or SysWOW64 for 64-bit systems). Note the file size and date, then compare against HP documentation for version 1.13.003 characteristics.Affected if The file exists but shows version 1.13.001 or earlier, or exists with no readable version attribute.
-
Verify ActiveX control registrationOpen Registry Editor and navigate to HKEY_CLASSES_ROOT\CLSID\ searching for OPOSMICR or check HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Code Store Database\Distribution Units\ for OPOSMICR.ocx registration entries.Affected if The OPOSMICR.ocx control is registered as an ActiveX component on the system.
-
Check HP OPOS service or driver versionOpen Programs and Features (appwiz.cpl) or the device manager for thermal receipt printers that use HP OPOS drivers. Look for entries named 'HP Ole Point Of Sale Driver' or similar HP OPOS components and note the installed version.Affected if The installed HP Ole Point Of Sale Driver shows version 1.13.001 or earlier.
-
Identify MICR-enabled printer installationsReview installed printer drivers on POS systems, particularly thermal receipt printers known to support MICR (magnetic ink character recognition) functionality used for check processing. Check printer documentation or driver info for MICR module inclusion.Affected if MICR-enabled receipt printers with HP OPOS drivers are installed on the system.
The system is affected if HP Ole Point Of Sale Driver version 1.13.001 or earlier is installed, the OPOSMICR.ocx ActiveX control is present and registered, and the system handles MICR-enabled printer functionality.

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 HP OPOS drivers to version 1.13.003 or later on all affected Point of Sale systems. Until patched, restrict network access to POS systems and disable OPOSMICR.ocx if possible.
OPOS driver version 1.13.003 or later
- Identify the current version of OLE Point of Sale (OPOS) driver installed on the HP Point of Sale system
- Navigate to the official HP support website (h20564.www2.hp.com) or contact HP support to obtain OPOS driver version 1.13.003 or later
- Download the updated OPOS driver package compatible with your HP Point of Sale system
- Backup current system state and configuration before applying the update
- Install the updated OPOS driver version 1.13.003 or later on the affected Windows PC
- Restart the system if required by the installation process
- Verify the installed driver version matches the fixed release (1.13.003 or higher)
