CVE-2025-20216 | Cisco Catalyst SD-WAN Manager Reflected HTML Injection Vulnerability

A vulnerability in the web interface of Cisco Catalyst SD-WAN Manager, formerly Cisco SD-WAN vManage, could allow an unauthenticated, remote attacker to inject HTML into the browser of an authenticated user. This vulnerability is due to improper sanitization of input to the web interface. An attacker could exploit this vulnerability by convincing an authenticated user to click a malicious link. A successful exploit could allow the attacker to inject HTML into the browser of an authenticated Cisco Catalyst SD-WAN Manager user.

Base score Version Severity Vector Exploitability Impact Score source
4.7 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.

User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
