      <title>CVE-2021-1590 — Cisco NX-OS Software system login block-for Denial of Service Vulnerability</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2021-1590</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Cisco NX-OS Software&lt;/p&gt;
&lt;p&gt;A vulnerability in the implementation of the system login block-for command for Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a login process to unexpectedly restart, causing a denial of service (DoS) condition. This vulnerability is due to a logic error in the implementation of the system login block-for command when an attack is detected and acted upon. An attacker could exploit this vulnerability by performing a brute-force login attack on an affected device. A successful exploit could allow the attacker to cause a login process to reload, which could result in a delay during authentication to the affected device.&lt;/p&gt;</description>
