Threats Tagged 'cve-2025-15387'

CVE-2025-15387 is a high-severity vulnerability in QNO Technology's VPN Firewall caused by insufficient entropy in session token generation. This flaw allows unauthenticated remote attackers to perform brute-force attacks to obtain active user sessions and subsequently log into the system without credentials. The vulnerability does not require prior authentication or special privileges, and no user interaction is needed. Exploitation could lead to full compromise of VPN firewall devices, exposing sensitive network traffic and internal resources. Although no known exploits are currently in the wild, the ease of exploitation and critical impact on confidentiality, integrity, and availability make this a significant threat. European organizations using QNO VPN Firewalls are at risk, especially those in sectors with high reliance on secure remote access. Mitigation requires immediate implementation of patches once available, enhanced monitoring for brute-force attempts, and network segmentation to limit exposure. Countries with notable QNO market presence and strategic infrastructure, such as Germany, France, and the UK, are likely to be most affected. Defenders should prioritize this vulnerability due to its potential to enable unauthorized access and lateral movement within networks.
