Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Immediately audit all user accounts with Observer or read-only roles to ensure credentials are secure and access is justified. 2. Implement strict credential management policies, including multi-factor authentication (MFA) for all users accessing Cisco DNA Center. 3. Monitor and log all configuration changes within DNA Center, focusing on actions performed by low-privileged users to detect anomalous behavior. 4. Restrict network access to the DNA Center management interface to trusted administrative networks and VPNs to reduce exposure. 5. Apply Cisco's official patches or updates as soon as they become available; monitor Cisco advisories for patch releases addressing this vulnerability. 6. Consider implementing compensating controls such as network segmentation and role reassessment to minimize the risk of privilege escalation. 7. Conduct regular penetration testing and RBAC reviews to identify and remediate similar privilege management issues proactively. 8. Educate administrators and users about the risks of credential compromise and enforce least privilege principles rigorously.

Description

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.

Impact

The primary impact of this vulnerability is on the integrity of network management operations. Unauthorized modification of policy configurations by low-privileged users can lead to significant security risks, including the introduction of malicious policies, bypassing security controls, or disrupting network operations. This can compromise the overall security posture of organizations relying on Cisco DNA Center for centralized network management. While confidentiality and availability impacts are minimal or none, the ability to alter configurations without proper authorization can facilitate further attacks or cause operational outages. Organizations with large-scale network deployments or critical infrastructure managed via Cisco DNA Center are particularly vulnerable, as attackers could leverage this flaw to gain persistent footholds or cause cascading failures. The requirement for valid credentials limits exploitation to insiders or attackers who have compromised user accounts, but the ease of privilege escalation once inside makes this a serious concern. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as threat actors may develop exploits over time.
