CVE Vulnerability Advisory Database
Filter vulnerabilities by CVSS severity, active CISA KEV exploitation, and technology stack.
Check Point Quantum Security Gateway Remote Code Execution (RCE) Vulnerability (CVE-2026-85102)
[Affected Scope] All Check Point Quantum Security Gateway versions with VPN Blade enabled.
[Impact] Unauthenticated remote attackers can execute arbitrary code with root privileges, leading to full gateway compromise.
[Mitigation] Immediately apply the latest Jumbo Hotfix and enforce strict certificate validation policies.
Palo Alto Networks PAN-OS GlobalProtect Authentication Bypass Vulnerability (CVE-2026-0257)
[Affected Scope] Palo Alto Networks PAN-OS software with GlobalProtect portal or gateway enabled (Panorama and Cloud NGFW are not impacted).
[Impact] Unauthenticated attackers can bypass security restrictions to establish unauthorized VPN connections and gain access to internal network resources.
[Mitigation] Apply the official security patches immediately, and restrict access to GlobalProtect interfaces until fully patched.
Array Networks ArrayOS AG OS Command Injection Vulnerability (CVE-2025-66644) Urgent Security Advisory
[Affected Scope] All Array Networks ArrayOS AG appliances running versions prior to 9.4.5.9
[Impact] High-privileged attackers can execute arbitrary OS commands, leading to complete system compromise and webshell deployment
[Mitigation] Immediately upgrade ArrayOS AG to version 9.4.5.9 or higher and audit system logs for indicators of compromise
WatchGuard Fireware OS IKEv2 Remote Code Execution (RCE) Vulnerability Urgent Security Advisory (CVE-2025-9242)
[Affected Scope] WatchGuard Firebox appliances running Fireware OS with IKEv2 Mobile User VPN or Branch Office VPN (BOVPN) configured with a dynamic gateway peer (including legacy configurations where static peers remain active)
[Impact] Unauthenticated remote attackers can execute arbitrary code with system privileges by sending specially crafted IKEv2 packets, leading to complete compromise of the appliance
[Mitigation] Immediately upgrade to the patched Fireware OS version, or temporarily disable IKEv2 VPN services and restrict access to trusted IP addresses
Cisco ASA and FTD Remote Access VPN (RAVPN) Resource Exhaustion Denial of Service Vulnerability (CVE-2024-20481) Security Advisory
[Affected Scope] Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software with Remote Access VPN (RAVPN) service enabled
[Impact] Unauthenticated, remote attackers can exhaust system resources by flooding VPN authentication requests, leading to a Denial of Service (DoS) of the RAVPN service and potentially requiring a device reload
[Mitigation] Apply official Cisco security patches immediately, configure connection rate limiting, and block malicious brute-force IP addresses
Check Point Security Gateway Remote Access VPN Arbitrary File Read Vulnerability (CVE-2024-24919) Technical Advisory
[Affected Scope] Check Point Security Gateways connected to the internet with Remote Access VPN or Mobile Access Software Blades enabled
[Impact] Unauthenticated remote attackers can read sensitive system files (e.g., /etc/shadow, password hashes, configuration files), potentially leading to credential theft and full network compromise
[Mitigation] Immediately apply the official hotfix provided in Check Point Advisory sk182336, audit system logs for IoCs, and rotate all sensitive credentials
Cisco ASA and FTD Remote Access VPN Unauthorized Access and Brute Force Vulnerability (CVE-2023-20269) Security Advisory
[Affected Scope] Remote access VPN feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software.
[Impact] Improper AAA separation allows unauthenticated remote attackers to conduct brute-force attacks to identify valid credentials or establish unauthorized clientless SSL VPN sessions.
[Mitigation] Apply official software updates from Cisco, or implement workarounds by redirecting default connection profile authentication to a loopback address and enforcing MFA.
Zyxel Firewall and VPN Devices IKE Packet Decoder Remote Command Injection Vulnerability (CVE-2023-28771) Analysis and Mitigation Guide
[Affected Scope] Zyxel ZyWALL/USG (4.60 to 4.73), VPN (4.60 to 5.35), USG FLEX (4.60 to 5.35), and ATP (4.60 to 5.35) series firmware
[Impact] An unauthenticated remote attacker can execute arbitrary OS commands with root privileges by sending crafted IKE UDP packets to the affected device
[Mitigation] Immediately upgrade to the latest official patched firmware version and restrict access to IKE ports (UDP 500/4500) from untrusted WAN interfaces
Pulse Connect Secure VPN Windows Resource Profiles Remote Code Execution Vulnerability Advisory (CVE-2021-22899)
[Affected Scope] Pulse Connect Secure (PCS) versions prior to 9.1R11.4
[Impact] A remote authenticated attacker can exploit the Windows Resource Profiles feature to execute arbitrary commands with root privileges on the VPN gateway, potentially compromising the internal network
[Mitigation] Immediately upgrade Pulse Connect Secure to version 9.1R11.4 or higher, apply the official XML workaround template, and perform compromise assessment
Pulse Connect Secure VPN Remote Code Execution (RCE) and Buffer Overflow Vulnerability (CVE-2021-22894) Security Advisory
[Affected Scope] Pulse Connect Secure versions prior to 9.1R11.4
[Impact] A remote authenticated attacker can execute arbitrary code with root privileges on the target system via a maliciously crafted meeting room.
[Mitigation] Immediately upgrade Pulse Connect Secure to version 9.1R11.4 or higher, and disable unused Meeting Room features.
Zyxel Firewalls and AP Controllers Hardcoded Admin Credentials Vulnerability (CVE-2020-29583) Analysis & Mitigation Guide
[Affected Scope] Zyxel USG, ATP, VPN, and ZyWALL series firewalls and AP controllers running ZLD firmware version 4.60
[Impact] Remote attackers can gain full administrative access to the device's SSH server or web interface using an undocumented hardcoded account ('zyfwp')
[Mitigation] Immediately upgrade to ZLD v4.60 Patch 1 or later, and restrict WAN-side access to management interfaces (SSH/HTTPS).
