      <title>CVE-2026-20122 — Cisco Catalyst SD-WAN Manager Arbitrary File Overwrite Vulnerability</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-20122</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Cisco Catalyst SD-WAN Manager&lt;/p&gt;
&lt;p&gt;A vulnerability in the API of Cisco Catalyst SD-WAN Manager could allow an authenticated, remote attacker to overwrite arbitrary files on the local file system. To exploit this vulnerability, the attacker must have valid read-only credentials with API access on the affected system.&#13;
&#13;
This vulnerability is due to improper file handling on the API interface of an affected system. An attacker could exploit this vulnerability by uploading a malicious file on the local file system. A successful exploit could allow the attacker to overwrite arbitrary files on the affected system&amp;amp;nbsp;and gain vmanage user privileges.&lt;/p&gt;</description>
