CVE-2026-24345 is a vulnerability identified in EZCast Pro II version 1.17478.146, involving improper input validation (CWE-20) that leads to a Cross-Site Request Forgery (CSRF) attack vector targeting the device's administrative user interface. CSRF attacks exploit the trust a web application places in the user's browser, allowing an attacker to perform unauthorized actions on behalf of an authenticated user. In this case, the vulnerability allows attackers to bypass authorization checks within the admin UI, effectively granting full administrative access without proper credentials or permissions. The vulnerability requires the attacker to have some level of prior authentication (PR:H) and user interaction (UI:A), indicating that the attacker must trick an authenticated user into executing malicious requests. The CVSS 4.0 vector indicates the attack is network-based (AV:A), with low attack complexity (AC:L), no privileges required (PR:H), and high impact on confidentiality, integrity, and availability (all high). No patches or known exploits are currently available, and the vulnerability was published on January 27, 2026. This flaw could allow attackers to manipulate device configurations, intercept or alter data streams, or disrupt device availability, posing significant risks in environments relying on EZCast Pro II for wireless display and collaboration. The root cause is improper input validation, which fails to adequately verify the legitimacy of requests to the admin UI, enabling CSRF exploitation.

For European organizations, the impact of CVE-2026-24345 can be significant, especially in sectors where EZCast Pro II devices are deployed for presentations, meetings, or collaborative workspaces. Unauthorized administrative access could lead to configuration changes that compromise device security, enable data leakage, or disrupt service availability. Confidential information displayed or transmitted via these devices could be intercepted or manipulated. The vulnerability could also serve as a foothold for lateral movement within corporate networks if attackers leverage compromised devices as pivot points. Educational institutions and enterprises using EZCast Pro II for remote or hybrid learning and collaboration are particularly at risk. The requirement for some authentication and user interaction reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks. The absence of patches increases exposure time, necessitating immediate mitigations to prevent potential breaches.

1. Implement strict network segmentation to isolate EZCast Pro II devices from critical network segments, limiting exposure to potential attackers. 2. Enforce strong access controls and multi-factor authentication for all administrative interfaces to reduce the risk of unauthorized access. 3. Educate users about phishing and social engineering tactics that could lead to CSRF exploitation, emphasizing caution when interacting with unsolicited links or requests. 4. Monitor network traffic and device logs for unusual or unauthorized administrative actions, enabling early detection of exploitation attempts. 5. Disable or restrict remote administrative access where possible, or limit it to trusted IP addresses and secure VPN connections. 6. Regularly review and update device firmware and software once patches become available from EZCast. 7. Consider deploying web application firewalls (WAFs) or intrusion prevention systems (IPS) that can detect and block CSRF attack patterns targeting the admin UI. 8. Collaborate with EZCast support channels to obtain updates and guidance on remediation.
