CVE-2025-46117 is a critical vulnerability affecting CommScope Ruckus Unleashed wireless controllers prior to versions 200.15.6.212.14 and 200.17.7.0.139, as well as Ruckus ZoneDirector controllers prior to version 10.5.1.0.279. The flaw resides in a hidden debug script named `.ap_debug.sh` that is accessible via the restricted command-line interface (CLI). This script fails to properly sanitize input parameters, leading to a command injection vulnerability (CWE-78). An attacker with authenticated access to the CLI can exploit this flaw to execute arbitrary commands with root privileges on the controller or on a specified target device managed by the controller. The vulnerability has a CVSS 3.1 base score of 9.1, indicating a critical severity level, with network attack vector, low attack complexity, high privileges required, no user interaction, and impacts on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the nature of the vulnerability and the high privileges gained make it a significant risk. The affected devices are network infrastructure components responsible for managing wireless access points, meaning successful exploitation could lead to full compromise of the wireless network management plane, unauthorized access to network traffic, lateral movement within the network, and potential disruption of wireless services. The vulnerability is particularly dangerous because it requires only authenticated access to the restricted CLI, which may be accessible to internal users or attackers who have compromised credentials. The lack of input sanitization in a debug script suggests a development oversight, and the hidden nature of the script may delay detection. No official patches or mitigation links were provided at the time of publication, emphasizing the need for immediate attention by affected organizations.

For European organizations, this vulnerability poses a severe threat to the security and stability of their wireless network infrastructure. Compromise of Ruckus Unleashed or ZoneDirector controllers could allow attackers to gain root-level control over critical network devices, enabling interception or manipulation of wireless traffic, unauthorized network access, and disruption of wireless services. This could affect enterprises, educational institutions, healthcare providers, and public sector organizations relying on Ruckus wireless solutions. The breach of confidentiality could expose sensitive data transmitted over the wireless network, while integrity and availability impacts could disrupt business operations and critical communications. Given the widespread use of Ruckus wireless products in Europe, especially in large organizations and public venues, the vulnerability could facilitate targeted attacks, espionage, or ransomware campaigns. The requirement for authenticated access reduces the risk from external attackers without credentials but increases the threat from insider attackers or those who have obtained valid credentials through phishing or other means. The critical severity and root-level command execution capability make this vulnerability a high priority for European organizations to address promptly to prevent potential compromise and operational disruption.

1. Immediate Steps: Restrict access to the CLI interface to trusted administrators only, using strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of credential compromise. 2. Network Segmentation: Isolate management interfaces of Ruckus controllers from general network access, limiting exposure to only necessary management stations. 3. Monitoring and Logging: Enable detailed logging and monitor CLI access for unusual or unauthorized activity, including attempts to invoke the `.ap_debug.sh` script or other suspicious commands. 4. Firmware Updates: Although no patches were listed at the time of disclosure, organizations should closely monitor CommScope’s official channels for firmware updates addressing this vulnerability and apply them immediately upon release. 5. Credential Hygiene: Enforce strong password policies and regularly rotate credentials used for accessing the controllers to minimize the risk of credential theft. 6. Incident Response Preparation: Develop and test incident response plans specifically for network infrastructure compromise scenarios, including isolating affected devices and forensic analysis. 7. Vendor Engagement: Engage with CommScope support to obtain guidance, potential workarounds, or early access to patches. 8. Disable Debug Features: Where possible, disable or restrict access to hidden debug scripts or features not required for normal operations to reduce attack surface.
