CVE-2013-0536
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 · uneditedntmulti.exe in the Multi User Profile Cleanup service in IBM Notes 8.0, 8.0.1, 8.0.2, 8.5, 8.5.1, 8.5.2, 8.5.3 before FP5, and 9.0 before IF2 allows local users to gain privileges via vectors that arrange for code to be executed during the next login session of a different user, aka SPR PJOK959J24.
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 confidenceLocal privilege escalation vulnerability in IBM Notes Multi User Profile Cleanup service (ntmulti.exe). A local authenticated user can manipulate code execution to run during another user's login session, allowing privilege escalation from a standard user to 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 IBM Notes version by looking at the About dialog or examining the program files directory for version information. On Windows, this is typically in the IBM Lotus Notes or IBM Notes program folder.Affected if The installed version matches exactly 8.0, 8.0.1, 8.0.2, 8.5, 8.5.1, 8.5.2.0, 8.5.3.0, or 9.0
-
Locate the ntmulti.exe service binarySearch for the file ntmulti.exe in the IBM Notes installation directory. This is the Multi User Profile Cleanup service that contains the vulnerability.Affected if The ntmulti.exe file exists in the IBM Notes installation folder, indicating the vulnerable component is present.
-
Verify Multi User Profile Cleanup service configurationCheck if the Multi User Profile Cleanup service is configured to run. On Windows, this can be checked via Services control panel or by examining startup entries related to IBM Notes.Affected if The Multi User Profile Cleanup service is installed and set to run, making the vulnerability exploitable.
-
Examine profile directory permissionsInspect file system permissions on user profile directories and temporary locations used by IBM Notes. Look for directories that could be modified by standard users where the service writes during another user's session.Affected if Standard (non-privileged) users have write access to profile directories or startup locations used by the Multi User Profile Cleanup service, allowing manipulation of code execution.
A user is affected if they have IBM Notes version 8.0 through 8.5.3.0 or 9.0 installed with the Multi User Profile Cleanup service (ntmulti.exe) enabled, and untrusted local users can write to profile directories used by that service.
Generated from the published advisory. Verify against your own configuration.
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 Notes patches: FP5 for 8.5.x versions or IF2 for 9.0, or upgrade to a fixed version. As this is a local vulnerability, ensure untrusted local users do not have write access to profile directories or startup locations.
