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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

CVE published 13 Nov 2025
Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Apply official Cisco patches or updates addressing CVE-2025-20349 as soon as they become available to remediate the vulnerability.
Restrict REST API access strictly to trusted users and systems, enforcing the principle of least privilege, and regularly audit user roles and permissions to minimize exposure.
Implement strong authentication mechanisms, such as multi-factor authentication (MFA), to reduce the risk of credential compromise.
Monitor API usage logs for anomalous or suspicious activity indicative of attempted command injection or unauthorized access.
Employ network segmentation and firewall rules to limit access to the DNA Center REST API endpoints from untrusted networks.
Conduct regular security assessments and penetration testing focused on API security and input validation controls.
Educate administrators and users on secure credential management and the risks associated with privilege escalation vulnerabilities.
Consider deploying runtime application self-protection (RASP) or web application firewalls (WAF) with custom rules to detect and block injection attempts targeting the REST API.

Description

A vulnerability in the REST API of Cisco Catalyst Center could allow an authenticated, remote attacker to execute arbitrary commands in a restricted container as the root user. This vulnerability is due to insufficient validation of user-supplied input in REST API request parameters. An attacker could exploit this vulnerability by sending a crafted API request to an affected device. A successful exploit could allow the attacker to inject arbitrary commands that would then be executed in a restricted container with root privileges. To exploit this vulnerability, the attacker must have valid credentials for a user account with at least the role of Observer.

Impact

The impact of CVE-2025-20349 is substantial for organizations using Cisco DNA Center as their network management solution. Successful exploitation enables attackers to execute arbitrary commands with root privileges within a containerized environment, potentially leading to full compromise of the DNA Center appliance. This can result in unauthorized access to sensitive network configuration data, disruption of network automation and monitoring functions, and lateral movement within the enterprise network. The integrity and availability of network management operations could be severely affected, causing operational downtime and increased risk of further attacks. Although exploitation requires valid credentials, insider threats or compromised accounts could be leveraged to exploit this vulnerability. Given Cisco DNA Center's widespread adoption in enterprise, government, and service provider networks globally, the vulnerability poses a risk to critical infrastructure and large-scale network environments.
