Palo Alto Networks PAN-OS Management Interface Remote Code Execution (RCE) Vulnerability (CVE-2026-0322)
[Affected Scope] Management interfaces of PA-Series, VM-Series firewalls, and Panorama (Virtual and M-Series) running PAN-OS
[Impact] An authenticated attacker with network access can execute arbitrary code with root privileges, leading to full system compromise
[Mitigation] Apply the latest security patches immediately and restrict management interface access to trusted internal IP addresses only
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 Authenticated File Read Vulnerability (CVE-2025-0111) Analysis and Mitigation Guide
[Affected Scope] PAN-OS firewalls with the management web interface enabled and accessible via the network (excluding Cloud NGFW and Prisma Access)
[Impact] Authenticated attackers can read sensitive system files on the PAN-OS filesystem that are readable by the 'nobody' user, potentially exposing configuration details
[Mitigation] Apply the latest PAN-OS security patches immediately and restrict management interface access to trusted internal IP addresses
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 DNS Security Denial of Service and Infinite Reboot Loop Vulnerability (CVE-2024-3393) Analysis and Mitigation Guide
[Affected Scope] Palo Alto Networks PAN-OS software versions with the DNS Security feature enabled
[Impact] An unauthenticated remote attacker can send malicious packets through the data plane, causing the firewall to reboot. Repeated exploitation forces the device into maintenance mode, leading to a complete network outage
[Mitigation] Immediately upgrade PAN-OS to the patched versions recommended by the vendor, and review DNS Security profile configurations as a temporary measure
Palo Alto Networks PAN-OS Privilege Escalation and Command Injection Vulnerability (CVE-2024-9474)
[Affected Scope] Authenticated administrators with access to the PAN-OS management web interface
[Impact] Complete system compromise via arbitrary OS command execution with root privileges on the firewall
[Mitigation] Apply official security patches immediately and restrict access to the management interface from the public internet
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 Expedition OS Command Injection Vulnerability (CVE-2024-9463) Security Advisory
[Affected Scope] Palo Alto Networks Expedition migration tool versions prior to 1.2.96
[Impact] Unauthenticated remote attackers can execute arbitrary OS commands as root, leading to the exposure of PAN-OS firewall usernames, cleartext passwords, device configurations, and API keys
[Mitigation] Immediately upgrade Expedition to version 1.2.96 or later, and rotate all potentially exposed firewall credentials and API keys
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 URL Filtering Misconfiguration Reflected TCP Denial-of-Service Vulnerability (CVE-2022-0028) Analysis and Mitigation Guide
[Affected Scope] Palo Alto Networks PAN-OS firewalls (PA-Series, VM-Series, CN-Series) configured with a URL filtering profile containing blocked categories assigned to a source zone with an external-facing interface.
[Impact] Remote attackers can abuse the firewall as a reflector and amplifier to launch high-volume TCP Reflected Denial-of-Service (RDoS) attacks against arbitrary targets, masking their identity.
[Mitigation] Apply official PAN-OS software updates immediately, or review and remove URL filtering profiles from security policies applied to external-facing source zones.
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 GlobalProtect Pre-Auth Remote Code Execution Vulnerability (CVE-2019-1579) Technical Advisory
[Affected Scope] PAN-OS 7.1.18 and earlier, PAN-OS 8.0.11-h1 and earlier, and PAN-OS 8.1.2 and earlier with GlobalProtect Portal or Gateway enabled.
