CVE-2023-50614 is a high-severity vulnerability affecting the EBYTE E880-IR01-V1.1 device. The vulnerability allows an unauthenticated attacker to obtain sensitive information by sending a specially crafted POST request to the /cgi-bin/luci endpoint. The vulnerability is classified under CWE-319, which relates to the cleartext transmission of sensitive information. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), the attack can be performed remotely over the network without any privileges or user interaction, and it results in a high impact on confidentiality, while integrity and availability remain unaffected. The lack of authentication and the network attack vector make this vulnerability particularly dangerous, as attackers can exploit it without any prior access or interaction. The vulnerability likely stems from improper handling or exposure of sensitive data in the web interface of the device, specifically through the /cgi-bin/luci endpoint, which is commonly associated with router or embedded device management interfaces. No patches or known exploits in the wild have been reported yet, but the high CVSS score indicates a significant risk if exploited. The absence of vendor and product details beyond the device model limits the scope of detailed technical mitigation, but the vulnerability clearly involves sensitive data leakage via web requests.

For European organizations, the impact of CVE-2023-50614 could be substantial, especially for those relying on EBYTE E880-IR01-V1.1 devices in their network infrastructure or IoT deployments. The exposure of sensitive information could lead to the compromise of confidential data, potentially including network configuration, credentials, or other critical operational details. This leakage could facilitate further attacks such as network intrusion, lateral movement, or espionage. Since the vulnerability does not affect integrity or availability directly, the immediate operational disruption risk is lower; however, the confidentiality breach alone can have severe consequences including regulatory non-compliance under GDPR, reputational damage, and financial loss. Organizations in sectors with high security requirements such as critical infrastructure, manufacturing, or telecommunications may be particularly vulnerable. The remote and unauthenticated nature of the exploit increases the risk of widespread scanning and exploitation attempts, especially if these devices are exposed to the internet or poorly segmented internal networks.

1. Network Segmentation: Isolate EBYTE E880-IR01-V1.1 devices from public internet access and restrict access to trusted management networks only. 2. Access Controls: Implement strict firewall rules to block unauthorized access to the /cgi-bin/luci endpoint and monitor for unusual POST requests targeting this path. 3. Device Hardening: Disable or restrict web management interfaces if not required, or configure them to require strong authentication and encrypted communication channels (e.g., HTTPS). 4. Monitoring and Detection: Deploy intrusion detection systems (IDS) and log analysis to identify attempts to exploit this vulnerability by detecting anomalous POST requests to the vulnerable endpoint. 5. Vendor Engagement: Engage with EBYTE or authorized distributors to obtain security patches or firmware updates addressing this vulnerability. If no patch is available, consider device replacement or additional compensating controls. 6. Incident Response Preparation: Prepare to respond to potential data leakage incidents by having clear procedures for containment, investigation, and notification in compliance with GDPR and other regulations. 7. Regular Audits: Conduct periodic security assessments of IoT and embedded devices to identify similar vulnerabilities and ensure compliance with security policies.
