CVE-2023-27505
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 · uneditedIncorrect default permissions in some Intel(R) Advanced Link Analyzer Standard Edition software installers before version 22.1 .1 may allow an authenticated user to potentially enable escalation of privilege via local access.
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 confidenceIntel Advanced Link Analyzer Standard Edition installers before version 22.1.1 ship with incorrect default file/folder permissions that allow an authenticated local user to modify executable locations or configurations, enabling local privilege escalation to higher-privilege accounts.

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.
-
Check if Intel Advanced Link Analyzer is installedLook for the product in Add/Remove Programs (Windows) or check for the installation directory under Program Files, typically in a folder named 'Intel' or 'Intel Advanced Link Analyzer'. On Linux, check common installation paths or use package management tools.Affected if The product is found installed on the system
-
Determine the installed versionCheck the installed version through Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ for the product, or look for a version file in the installation directory. Compare the version number to the affected range (versions before 22.1).Affected if The installed version is earlier than 22.1 (for example, 22.0.x or any version below 22.1)
-
Inspect installation directory permissionsRight-click the Intel Advanced Link Analyzer installation folder, go to Properties > Security, and examine which users and groups have permissions. Specifically check for 'Write' or 'Modify' permissions granted to 'Users' or 'Authenticated Users' groups on folders containing executable files (.exe) or configuration files (.xml, .ini, .cfg).Affected if Authenticated users or the Users group has Write or Modify permissions on directories containing executable files or configuration files
-
Check executable file permissionsReview permissions on .exe files in the installation directory. Right-click each executable, check Properties > Security, and verify whether non-privileged users have permission to modify, replace, or delete these files.Affected if Non-administrator users can modify or replace executable files in the installation directory
-
Check configuration file permissionsExamine permissions on configuration files (XML, INI, CFG files) in the installation directory and subdirectories. Determine if authenticated users can edit these files which could be used to point executables to malicious locations.Affected if Configuration files are writable by authenticated local users
A user is affected if Intel Advanced Link Analyzer version 22.1 or earlier is installed AND the installation directory or its contents (executables/configurations) grant Write or Modify permissions to authenticated local users, allowing privilege escalation.

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 · scoped22.1
Upgrade to Intel Advanced Link Analyzer Standard Edition version 22.1.1 or later which corrects the default permission settings in the installer.
22.1.1 or later
- Download Intel Advanced Link Analyzer version 22.1.1 or later from the official Intel download site
- Verify the downloaded installer checksum against Intel's published hash
- Close any running instances of Intel Advanced Link Analyzer
- Run the installer with administrative privileges
- Follow the on-screen installation prompts to complete the upgrade
- After installation, verify the installed version is 22.1.1 or later
