      <title>CVE-2021-1592 — Cisco UCS Manager Software SSH Sessions Denial of Service Vulnerability</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2021-1592</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Cisco Unified Computing System (Managed)&lt;/p&gt;
&lt;p&gt;A vulnerability in the way Cisco UCS Manager software handles SSH sessions could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper resource management for established SSH sessions. An attacker could exploit this vulnerability by opening a significant number of SSH sessions on an affected device. A successful exploit could allow the attacker to cause a crash and restart of internal Cisco UCS Manager software processes and a temporary loss of access to the Cisco UCS Manager CLI and web UI. Note: The attacker must have valid user credentials to authenticate to the affected device.&lt;/p&gt;</description>
