Technical details

An XML External Entity (XXE) vulnerability exists in the web UI of Cisco Catalyst SD-WAN Manager (formerly vManage). The flaw is caused by improper handling of XXE entries when the system parses XML files. A remote, unauthenticated attacker can exploit this by sending a specially crafted XML request to the affected system's web interface. Successful exploitation allows the attacker to read arbitrary files from the underlying filesystem, potentially leading to information disclosure. Cisco has released software updates to address this vulnerability; administrators should refer to the vendor advisory for specific fixed versions across the various release branches.
