CVE-2026-18759 An improper authentication and path traversal vulnerability exists in ASUSTOR Backup Plan and ASUSTOR EZ Sync.

The background service of ABP or AES runs as NT AUTHORITY\SYSTEM and implements a file-based inter-process communication IPC mechanism protected by AES encryption. Because the encryption key file is readable by standard users and protected using DPAPI. Any authenticated local user can recover the...

CVE-2026-15430: Improper Privilege Management

Improper access control in the IRPMJWRITE command interface in Wellbia XIGNCODE3 xhunter2.sys, version 2026.6.1.192, allows a local, unprivileged attacker to achieve local privilege escalation to NT AUTHORITY\SYSTEM, extract credentials from PPL-protected lsass.exe, and terminate PPL-protected...

CVE-2026-11771

A flaw was found in OpenVPN. A remote attacker could exploit an off-by-one buffer write vulnerability during NTLM NT LAN Manager proxy authentication. By sending a specially crafted NTLM response from a malicious proxy server, the attacker could cause the OpenVPN client to crash, leading to a...

CVE-2026-11771

OpenVPN version 2.1.0 through 2.6.20 and 2.7alpha1 through 2.7.4 allows attackers via an off-by-one buffer write in the NTLM proxy authentication to potentially cause a crash via a crafted NTLM response from a malicious proxy server...

CVE-2026-11771

OpenVPN vulnerability CVE-2026-11771 affects OpenVPN versions 2.1.0–2.6.20 and 2.7_alpha1–2.7.4. Root cause: an off-by-one buffer write in the NTLM proxy authentication handling, which can be triggered by a crafted NTLM response from a malicious proxy server. Impact: potential crash of the OpenVP...

CVE-2026-64389

A flaw was found in the Linux kernel's ksmbd component. A remote attacker could exploit a vulnerability in the NTLMv2 authentication process to modify a session key even when authentication fails.
