CVE-2018-1411
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 · uneditedIBM Notes Diagnostics (IBM Client Application Access and IBM Notes) could allow a local user to execute commands on the system. By crafting a command line sent via the shared memory IPC, which could be tricked into executing an executable chosen by the attacker. IBM X-Force ID: 138710.
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 confidenceIBM Notes Diagnostics contains a vulnerability in its shared memory IPC mechanism that allows a local authenticated user to craft malicious command lines, tricking the application into executing attacker-controlled executables with elevated privileges.

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 IBM Notes installation and versionCheck the installed version of IBM Notes on the system using the system\'s software inventory or by examining the Notes executable properties (typically in C:\Program Files\IBM\Notes or similar location).Affected if The installed version matches 8.5.1.5, 8.5.2.4, 8.5.3.6, 9.0, or 9.0.1.9.
-
Identify IBM Client Application Access installation and versionCheck the installed version of IBM Client Application Access through system software listings or by examining the application properties in Program Files.Affected if The installed version matches 1.0.0.1, 1.0.1, or 1.0.1.2.
-
Confirm Diagnostics component presenceLocate the IBM Notes Diagnostics module on the system. This is typically found within the Notes program directory or as a separate diagnostics tool component.Affected if The Diagnostics component is present and accessible on the system.
-
Verify shared memory IPC exposureExamine if the shared memory IPC mechanism used by IBM Notes Diagnostics is exposed or accessible to local users. This may involve checking file permissions on Notes data directories or IPC-related configurations.Affected if Local authenticated users have write access to shared memory resources used by the Diagnostics component.
-
Monitor for unauthorized process executionReview system process listings and look for unexpected executables spawned by IBM Notes processes, particularly from the diagnostics module or related services.Affected if Unusual or unauthorized executables are being launched by IBM Notes components with elevated privileges.
A system is affected if IBM Notes (versions 8.5.1.5 through 9.0.1.9) or IBM Client Application Access (versions 1.0.0.1 through 1.0.1.2) with the Diagnostics component is installed and the shared memory IPC mechanism is accessible to local authenticated 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 IBM security patches for CVE-2018-1411 when available; until then, restrict local access to trusted users and monitor for suspicious process execution from IBM Notes components.
