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 buffer over-read in Ivanti Secure Access Client before 22.7R4 allows a local unauthenticated attacker to cause a denial of service.
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 confidenceA buffer over-read vulnerability in Ivanti Secure Access Client versions before 22.7R4 allows a local unauthenticated attacker to read beyond the allocated memory buffer, causing a denial of service condition.

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 Ivanti Secure Access Client installationOpen Windows Programs and Features (appwiz.cpl) or check the installation directory (commonly C:\Program Files\Ivanti\Secure Access Client\) for the ISAgent.exe or isaclient.exe executableAffected if The application is installed on the local machine
-
Determine installed version numberRight-click the main executable (ISAgent.exe or isaclient.exe), select Properties, then view the Details tab to see the File Version. Alternatively, run 'Get-ItemProperty' in PowerShell on the executable pathAffected if The version displayed is 22.7 or any version lower than 22.7 (for example, 22.6.x, 22.5.x, etc.)
-
Confirm version is before 22.7R4Compare your installed version against the affected ranges: versions < 22.7 and version = 22.7 are vulnerable. The fixed version is 22.7R4 or laterAffected if The installed version is 22.7 or any version prior to 22.7R4 (such as 22.7, 22.6, 22.5, etc.)
If the installed Ivanti Secure Access Client version is 22.7 or any version earlier than 22.7R4, the local buffer over-read vulnerability is present and the system is affected.
