CVE-2026-20128 Detail

Description

A vulnerability in the Data Collection Agent (DCA) feature of Cisco Catalyst SD-WAN Manager could allow an authenticated, local attacker to gain DCA user privileges on an affected system. To exploit this vulnerability, the attacker must have valid vmanage credentials on the affected system. This vulnerability is due to the presence of a credential file for the DCA user on an affected system. An attacker could exploit this vulnerability by accessing the filesystem as a low-privileged user and reading the file that contains the DCA password from that affected system. A successful exploit could allow the attacker to access another affected system and gain DCA user privileges. Note: Cisco Catalyst SD-WAN Manager releases 20.18 and later are not affected by this vulnerability.
