CVE-2022-45228 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Dragino LoRa LG01 IoT gateway, specifically version 4.3.4. The vulnerability exists on the logout page of the device's web interface. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a forged request to the vulnerable application without their consent. In this case, an attacker could potentially cause a logged-in user to unknowingly trigger a logout action by sending a crafted request, disrupting the user's session. The CVSS v3.1 base score is 3.5, indicating a low severity level. The vector string (AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N) shows that the attack can be performed remotely over the network with low attack complexity, requires low privileges, and user interaction is needed. The impact is limited to integrity, with no confidentiality or availability impact. No known exploits have been reported in the wild, and no patches or vendor advisories are currently available. The vulnerability is categorized under CWE-352, which corresponds to CSRF attacks. Given the nature of the vulnerability, it does not allow direct data theft or system compromise but could be used as part of a broader attack chain to disrupt user sessions or cause minor integrity issues in device management.

For European organizations deploying Dragino LoRa LG01 gateways, particularly in IoT and smart city infrastructure, this vulnerability could lead to unintended session terminations if exploited. While the direct impact is low, repeated forced logouts could disrupt device management workflows, causing operational inefficiencies. In critical IoT deployments such as environmental monitoring, industrial automation, or smart metering, session disruptions might delay configuration changes or monitoring activities, indirectly affecting service reliability. However, since the vulnerability does not allow data leakage or device takeover, the risk to confidentiality and availability is minimal. The requirement for user interaction and low privileges limits large-scale automated exploitation. Nonetheless, organizations relying on these devices should be aware of the potential for minor integrity impacts and plan accordingly to maintain operational continuity.

1. Implement CSRF tokens on all state-changing requests, including logout actions, to ensure that requests originate from legitimate user sessions. 2. Enforce same-site cookie attributes (SameSite=Lax or Strict) to reduce the risk of CSRF attacks via cross-origin requests. 3. Require explicit user confirmation for logout actions to prevent automated or hidden logout requests. 4. Monitor device firmware updates from Dragino and apply patches promptly once available. 5. Restrict administrative access to the device management interface to trusted networks or VPNs to reduce exposure. 6. Employ web application firewalls (WAFs) with rules targeting CSRF attack patterns to provide an additional layer of defense. 7. Educate users and administrators about the risks of CSRF and encourage cautious behavior when interacting with device management interfaces, especially avoiding clicking on suspicious links while logged in. 8. Consider network segmentation for IoT devices to limit the impact of potential session disruptions on critical infrastructure.
