CVE-2025-20346 | Cisco Catalyst Center Privilege Escalation Vulnerability

A vulnerability in Cisco Catalyst Center could allow an authenticated, remote attacker to execute operations that should require Administrator privileges. The attacker would need valid read-only user credentials. This vulnerability is due to improper role-based access control (RBAC). An attacker could exploit this vulnerability by logging in to an affected system and modifying certain policy configurations. A successful exploit could allow the attacker to modify policy configurations that are reserved for the Administrator role. To exploit this vulnerability, the attacker must have valid credentials for a user account with at least the role of Observer.

4.3 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/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:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
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.
Availability (A:N)
Service keeps running; no real outage angle.
