Attack Vector: Local
Attack Complexity: Low
Privileges Required: High
User Interaction: None
Scope: Unchanged
Confidentiality: High
Integrity: High
Availability: None

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to 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 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.

What to do

AI-suggested

Organizations should immediately restrict CLI access to the Cisco DNA Spaces Connector to trusted administrators only, enforcing strong authentication and monitoring for suspicious login activity. Applying vendor patches or updates as soon as they become available is critical to remediate the vulnerability. Until patches are deployed, consider implementing compensating controls such as network segmentation to limit access to the device CLI and employing host-based intrusion detection to detect anomalous command executions. Regularly audit user privileges and remove unnecessary spacesadmin accounts. Employ strict input validation and command execution policies if custom scripts or automation interact with the CLI. Additionally, maintain comprehensive logging and alerting on CLI command usage to detect potential exploitation attempts early. Finally, conduct security awareness training for administrators to recognize and report suspicious activity.

Description

A vulnerability in Cisco Spaces Connector could allow an authenticated, local attacker to elevate privileges and execute arbitrary commands on the underlying operating system as root. This vulnerability is due to insufficient restrictions during the execution of specific CLI commands. An attacker could exploit this vulnerability by logging in to the Cisco Spaces Connector CLI as the spacesadmin user and executing a specific command with crafted parameters. A successful exploit could allow the attacker to elevate privileges from the spacesadmin user and execute arbitrary commands on the underlying operating system as root.

Impact

If exploited, this vulnerability allows an attacker with authenticated local CLI access to escalate privileges to root and execute arbitrary commands on the underlying operating system. This can lead to complete system compromise, including unauthorized access to sensitive data, modification or deletion of critical files, installation of persistent malware, and disruption of services. Since the attacker must already have spacesadmin CLI access, the vulnerability primarily elevates the risk posed by insider threats or attackers who have obtained legitimate credentials. The high impact on confidentiality and integrity means organizations could suffer data breaches, loss of trust, and operational disruptions. Given the root-level access, attackers could pivot to other network segments or devices, increasing the scope of compromise. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially in environments with weak access controls.
