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.
Palo Alto Networks PAN-OS User-ID Authentication Portal Buffer Overflow RCE Vulnerability (CVE-2026-0300)
[Affected Scope] Palo Alto Networks PAN-OS software running on PA-Series and VM-Series firewalls with the User-ID™ Authentication Portal (Captive Portal) service enabled.
[Impact] An unauthenticated remote attacker can execute arbitrary code with root privileges on the firewall by sending specially crafted packets.
[Mitigation] Apply the latest security patches immediately, and restrict access to the User-ID™ Authentication Portal to trusted internal IP addresses only.
Palo Alto Networks PAN-OS Management Web Interface Authentication Bypass Vulnerability (CVE-2025-0108) Emergency Security Advisory
[Affected Scope] Palo Alto Networks PAN-OS software management web interface (excluding Cloud NGFW and Prisma Access)
[Impact] Unauthenticated remote attackers with network access can bypass authentication on the management interface and invoke sensitive PHP scripts, severely compromising system integrity and confidentiality
[Mitigation] Immediately upgrade to the patched PAN-OS versions and restrict access to the management interface to trusted internal IP addresses only
Palo Alto Networks PAN-OS Management Interface Authentication Bypass Vulnerability (CVE-2024-0012) Urgent Security Advisory
[Affected Scope] Palo Alto Networks firewall appliances running PAN-OS 10.2, 11.0, 11.1, and 11.2 with the management web interface exposed to the network.
[Impact] Unauthenticated remote attackers can bypass authentication to gain administrative privileges, modify configurations, or chain with other privilege escalation flaws like CVE-2024-9474 to compromise the system.
[Mitigation] Immediately upgrade to the patched PAN-OS versions and restrict management interface access to trusted internal IP addresses only.
Palo Alto Networks PAN-OS GlobalProtect Remote Code Execution Vulnerability Advisory (CVE-2024-3400)
[Affected Scope] Palo Alto Networks PAN-OS 10.2, 11.0, and 11.1 firewalls with GlobalProtect gateway or portal enabled
[Impact] Unauthenticated remote attackers can execute arbitrary OS commands with root privileges on the firewall via specially crafted requests
[Mitigation] Immediately apply the official PAN-OS hotfix, or implement temporary workarounds such as disabling Device Telemetry or applying Threat Prevention signatures
Palo Alto Networks PAN-OS SAML Signature Verification Bypass Vulnerability (CVE-2020-2021)
[Affected Scope] PAN-OS 8.1, 9.0, and 9.1 versions, Panorama, and GlobalProtect gateways with SAML authentication enabled and 'Validate Identity Provider Certificate' disabled
[Impact] Unauthenticated remote attackers can bypass SAML signature verification to gain administrative access to PAN-OS/Panorama web interfaces or access protected network resources
[Mitigation] Upgrade PAN-OS to patched versions (9.1.3, 9.0.9, 8.1.15 or later) or enable the 'Validate Identity Provider Certificate' option in the SAML Identity Provider Server Profile
Palo Alto Networks PAN-OS Management Interface Remote Code Execution (RCE) Vulnerability Analysis and Mitigation Guide (CVE-2017-15944)
[Affected Scope] PAN-OS versions before 6.1.19, 7.0.19, 7.1.14, and 8.0.6 management interface
[Impact] Unauthenticated remote attackers can execute arbitrary system commands with root privileges via the management interface, leading to complete device compromise
[Mitigation] Immediately upgrade to the patched versions and restrict access to the management interface from the public internet
