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
A vulnerability in the Veriexec subsystem of Juniper Networks Junos OS allowing an attacker to fully compromise the host system. A local authenticated user can elevate privileges to gain full control of the system even if they are specifically denied access to perform certain actions. This issue affects: Juniper Networks Junos OS: 12.3X48 versions prior to 12.3X48-D80 on SRX Series.

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 confidence

A local authenticated privilege escalation vulnerability exists in the Veriexec subsystem of Juniper Networks Junos OS on SRX Series devices. An attacker with local authenticated access can bypass explicit access controls and elevate privileges to root, achieving full system compromise.

MitigationUpgrade Junos OS to version 12.3X48-D80 or later on affected SRX Series devices to remediate this vulnerability.

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. Confirm device is SRX Series
    Run `show chassis hardware` or `show system information` and verify the model listed is an SRX platform (SRX100, SRX110, SRX210, SRX220, SRX240, SRX340, SRX345, SRX550, SRX650, or SRX5400/5600/5800 series)
    Affected if Device model is any SRX Series platform
  2. Check installed Junos OS version
    Run `show version` and locate the Junos OS version string (typically displayed as something like 12.3X48-Dxx)
    Affected if Version shown is exactly 12.3x48 (the equals sign indicates only this specific version is affected)
  3. Verify Veriexec subsystem is active
    Run `show system verification` or check the Veriexec status using `veriexec` related commands if available on the device
    Affected if Veriexec is enabled and actively enforcing integrity checks on the system
  4. Confirm local authenticated access exists
    Review `show system users` or check for locally configured user accounts with shell access via `show configuration system login`
    Affected if Local user accounts with authenticated shell or CLI access are present on the device

A user is affected if they are running Junos OS version 12.3x48 exactly on an SRX Series device with Veriexec enabled and have or could have local authenticated user accounts present on the system.
