CVE-2024-12831
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 · uneditedArista NG Firewall uvm_login Incorrect Authorization Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Arista NG Firewall. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the uvm_login module. The issue results from incorrect authorization. An attacker can leverage this to escalate privileges to resources normally protected from the user. Was ZDI-CAN-24324.
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 confidenceThis is a privilege escalation vulnerability in Arista NG Firewall's uvm_login module caused by incorrect authorization logic. An attacker who already has the ability to execute low-privileged code on the target system can exploit this flaw to gain access to resources that should be protected from their current privilege level.

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.
-
Identify installed Arista NG Firewall versionUse system administration commands or check the firewall's web interface/dashboard for the current software version informationAffected if The installed version is 17.1.1 specifically
-
Confirm uvm_login module is in useCheck the firewall configuration for the uvm_login module being enabled or configured for user authenticationAffected if The uvm_login module is actively handling login/authentication processes on the firewall
-
Verify current authorization configurationReview user role assignments and privilege levels configured in the uvm_login module settingsAffected if Low-privileged users exist in the system who should have restricted access to higher-privilege resources
You are affected if Arista NG Firewall version 17.1.1 is running and the uvm_login module is handling authentication with users at different privilege levels present.
