Source: CVE Database V5
Vendor/Project: Cisco
Product: Cisco DNA Spaces Connector

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.

Technical Analysis

CVE-2025-20308 is a vulnerability identified in Cisco DNA Spaces Connector, a product designed to integrate and manage location-based services within enterprise networks. The vulnerability arises from improper neutralization of special elements used in OS command execution, specifically within the CLI commands available to the 'spacesadmin' user. An authenticated local attacker with access to the CLI can exploit this flaw by supplying crafted parameters to specific commands, resulting in OS command injection. This allows the attacker to escalate privileges from the spacesadmin user to root, thereby gaining full control over the underlying operating system. The vulnerability affects multiple versions of the Connector released between January 2023 and January 2025, indicating a long window of exposure. The CVSS v3.1 score is 6.0 (medium severity), reflecting that the attack vector requires local access and high privileges (spacesadmin user), but no user interaction is needed. The impact on confidentiality and integrity is high, as arbitrary root-level commands can be executed, but availability impact is rated low. No known exploits are currently reported in the wild, and no patches are linked yet. The root cause is insufficient input validation or sanitization of CLI parameters, allowing injection of OS commands. This vulnerability is significant because Cisco DNA Spaces Connector is often deployed in enterprise environments to manage network location services, and root-level compromise could lead to lateral movement, data exfiltration, or disruption of network services.

Potential Impact

For European organizations, the impact of this vulnerability could be substantial, especially for enterprises and service providers relying on Cisco DNA Spaces Connector for location-based network services. Successful exploitation would allow attackers to gain root access on the device, potentially compromising sensitive network infrastructure and data. This could lead to unauthorized access to internal systems, manipulation or theft of location data, and disruption of network operations. Given the role of Cisco DNA Spaces in managing network environments, attackers could pivot to other critical systems, increasing the risk of broader network compromise. The requirement for authenticated local access limits the attack surface but insider threats or attackers who have already gained initial access could leverage this vulnerability to escalate privileges. This elevates risks related to insider attacks or post-compromise lateral escalation within European organizations. Additionally, regulatory frameworks such as GDPR impose strict requirements on data protection; a breach involving location or network data could result in significant compliance and reputational consequences.

Mitigation Recommendations

To mitigate this vulnerability, European organizations should: 1) Immediately audit and restrict access to the Cisco DNA Spaces Connector CLI, ensuring only trusted administrators have 'spacesadmin' credentials. 2) Implement strict access controls and monitoring on devices running the Connector to detect any unauthorized CLI access attempts. 3) Apply principle of least privilege by limiting the number of users with spacesadmin access and consider using multi-factor authentication for CLI access if supported. 4) Monitor Cisco's official advisories closely for patches or updates addressing this vulnerability and prioritize timely deployment once available. 5) As a temporary workaround, consider isolating the Connector devices from less trusted network segments to reduce the risk of local attacker presence. 6) Conduct internal training and awareness to prevent credential compromise and insider threats. 7) Employ host-based intrusion detection systems (HIDS) on Connector devices to detect suspicious command executions or privilege escalations. These steps go beyond generic advice by focusing on access control hardening, monitoring, and isolation specific to the nature of this vulnerability.
