Résumé

On affected platforms running Arista EOS with password authentication configured, a specially crafted password can create orphan authentication sessions. Repeated exploitation of this issue can exhaust available authentication resources, resulting in legitimate users being unable to log in to the device.

This issue was discovered internally by Arista, and the company is not aware of any malicious exploitation of this vulnerability in customer networks.

Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
