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 · unedited
An information exposure vulnerability in the Palo Alto Networks Cortex XDR agent on Windows devices allows a local system administrator to disclose the admin password for the agent in cleartext, which bad actors can then use to execute privileged cytool commands that disable or uninstall the agent.

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 confidence

The Cortex XDR agent on Windows stores or transmits the admin password in an insecure manner, allowing a local administrator with debug or diagnostic access to recover the cleartext password. This password can then be used with the cytool command-line utility to execute privileged operations including disabling or uninstalling the agent's protection capabilities.

MitigationApply the vendor patch from Palo Alto Networks for Cortex XDR agent. Until patched, monitor local administrative access and review logs for suspicious cytool command execution.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Cortex XDR agent version
    Open Windows Control Panel, go to Programs and Features, or run 'cytool.exe version' if available. Compare the installed version against the affected range: versions 7.5 through 7.5.100 (anything >= 7.5 but < 7.5.101).
    Affected if Installed version is 7.5.x where x is less than 101, or version starts with 7.5 and is not exactly 7.5.101 or higher.
  2. Verify cytool.exe is present
    Locate cytool.exe in the Cortex XDR installation directory, typically found in C:\Program Files\Palo Alto Networks\Traps\ or C:\Program Files\Palo Alto Networks\Cortex\XDR\. Check if the file exists and note its metadata.
    Affected if The cytool.exe utility is present on the system, as this is the command that can use the recovered admin password.
  3. Review cytool command execution history
    Check Windows Event Logs under Security and Application logs for invocations of cytool.exe, particularly commands that disable protection, stop the agent, or uninstall the software. Also check for any scheduled tasks or scripts that invoke cytool.
    Affected if There are logged executions of cytool.exe with arguments related to disabling, stopping, or uninstalling the agent.
  4. Audit local administrative access
    Review Windows Security Event Log Event ID 4624 for local administrator account logons, particularly looking for accounts with debug or diagnostic access to the system.
    Affected if Local administrator accounts with debug or diagnostic capabilities have authenticated to the system.
  5. Inspect for debug or diagnostic artifacts
    Search the Cortex XDR installation directory and Windows Temp folders for debug logs, memory dumps, or diagnostic export files that may contain cleartext password data.
    Affected if Debug logs, diagnostic exports, or memory dumps containing admin password strings are found.

The environment is affected if the Cortex XDR agent version is 7.5 or higher but below 7.5.101 AND local administrative or diagnostic access exists that could have exposed the insecurely stored admin password.

Upgrade available Upgrade to 7.5.101 or later
Fixed in 7.5.101
Interim mitigation

Apply the vendor patch from Palo Alto Networks for Cortex XDR agent. Until patched, monitor local administrative access and review logs for suspicious cytool command execution.

Recommended fix High confidence

Cortex XDR Agent 7.5.101 or later

  1. Verify current Cortex XDR Agent version on Windows devices using the cytool info command or through the Cortex XDR console
  2. Download Cortex XDR Agent version 7.5.101 or later from the Palo Alto Networks Support Portal
  3. Deploy the upgraded agent to all affected Windows endpoints using your standard deployment method (e.g., Cortex XDR management console, group policy, or enterprise software distribution tool)
  4. Verify the upgrade was successful by checking the agent version on managed devices
  5. Confirm that the admin password is no longer exposed in cleartext
