CVE-2025-7850 is an OS command injection vulnerability identified in TP-Link Systems Inc.'s Omada gateways, which are network devices used for managing enterprise Wi-Fi and network infrastructure. The vulnerability is classified under CWE-78, indicating improper neutralization of special elements used in OS commands. This flaw allows an attacker who has already authenticated as an administrator on the device's web portal to inject and execute arbitrary OS commands. The vulnerability arises because the web interface fails to properly sanitize or validate input before incorporating it into system-level commands, enabling command injection. The CVSS 4.0 vector (AV:A/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:H) indicates that the attack requires network access with low complexity, no user interaction, and high privileges (admin authentication). The impact on confidentiality, integrity, and availability is high, as arbitrary commands can compromise the device, extract sensitive data, alter configurations, or disrupt network operations. Although no known exploits are currently in the wild, the critical severity and ease of exploitation post-authentication make this a significant threat. No patches have been published yet, so organizations must rely on compensating controls until updates are available.

For European organizations, this vulnerability poses a substantial risk, particularly for enterprises and service providers relying on TP-Link Omada gateways for network management. Successful exploitation could lead to full compromise of the gateway device, enabling attackers to intercept or manipulate network traffic, disrupt connectivity, or pivot to internal networks. This could affect confidentiality of sensitive communications, integrity of network configurations, and availability of critical network services. Sectors such as finance, healthcare, government, and critical infrastructure are especially vulnerable due to the potential for operational disruption and data breaches. The requirement for admin authentication limits exposure to insider threats or attackers who have already compromised credentials, but the high impact and lack of patches increase urgency. Additionally, supply chain risks exist if these devices are used widely in managed service provider environments.

1. Restrict administrative access to Omada gateways by enforcing strong authentication mechanisms such as multi-factor authentication (MFA) and limiting access to trusted IP ranges or VPNs. 2. Monitor administrative logs and network traffic for unusual command execution patterns or unauthorized configuration changes. 3. Implement network segmentation to isolate management interfaces from general user networks, reducing exposure. 4. Regularly audit and rotate administrator credentials to minimize risk from compromised accounts. 5. Until official patches are released, consider disabling or limiting web portal access where feasible or using alternative management methods. 6. Engage with TP-Link support channels to obtain early updates or workarounds and apply firmware updates promptly once available. 7. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect command injection attempts targeting Omada gateways. 8. Educate administrators about the risks of this vulnerability and the importance of secure credential handling.
