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
Improper Privilege Management vulnerability in AlgoSec Firewall Analyzer on Linux, 64 bit allows Privilege Escalation, Parameter Injection. A local user with access to the command line may escalate their privileges by abusing the parameters of a command that is approved in the sudoers file.  This issue affects Firewall Analyzer: A33.0, A33.10.

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

Improper Privilege Management in AlgoSec Firewall Analyzer allows a local user with sudo access to escalate privileges by injecting malicious parameters into commands permitted in the sudoers file. This is a classic sudo privilege escalation where the sudoers configuration allows a command without properly restricting or validating the arguments that can be passed.

MitigationReview and harden the sudoers configuration to remove or strictly restrict commands that allow parameter injection. Implement full command path restrictions and disallow argument passing for sudo-enabled commands.

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. Identify installed AlgoSec Firewall Analyzer version
    Run the command to display the installed version of AlgoSec Firewall Analyzer (e.g., 'dpkg -l | grep algosec', 'rpm -qi algosec-firewall-analyzer', or check the product's About/Version UI).
    Affected if The installed version is exactly a33.0 or a33.10.
  2. Locate sudoers configuration files
    Examine /etc/sudoers and any included files in /etc/sudoers.d/ for entries related to AlgoSec or the affected product user accounts.
    Affected if There are sudoers entries that grant sudo access to AlgoSec-related commands or scripts.
  3. Inspect sudoers command arguments
    Review each AlgoSec-related sudoers entry for whether the command specification allows arbitrary arguments (e.g., uses wildcard (*) or lacks explicit argument restrictions).
    Affected if The sudoers configuration permits the sudo-enabled command to accept user-supplied arguments without strict validation.
  4. Verify command path restrictions
    Check if the sudoers entries use full absolute paths to binaries or scripts, and whether they restrict or forbid passing additional arguments after the command.
    Affected if The sudoers entries do not enforce full command path restrictions or explicitly disallow argument passing.

A user is affected if AlgoSec Firewall Analyzer version a33.0 or a33.10 is installed AND the sudoers configuration contains entries that grant sudo access to AlgoSec commands without properly restricting or validating arguments.
