Netgate pfSense CE 2.8.0 allows code execution in the XMLRPC API via pfsense.execphp. NOTE: the Supplier disputes this because the API call is only available to admins and they are intentionally allowed to execute PHP code.

An issue was discovered in pfSense through 2.4.4-p3. widgets/widgets/picture.widget.php uses the widgetkey parameter directly without sanitization (e.g., a basename call) for a pathname to filegetcontents or fileputcontents.

Apcupsd 0.3.915, as used in pfSense through 2.4.4-RELEASE-p3 and other products, has an Arbitrary Command Execution issue in apcupsdstatus.php.

pfSense pfBlockerNG through 2.1.426 allows remote attackers to execute arbitrary OS commands as root via shell metacharacters in the HTTP Host header. NOTE: 3.x is unaffected.

Improper restriction of excessive authentication attempts in the SSHGuard component of Netgate pfSense Plus software v22.05.1 and pfSense CE software v2.6.0 allows attackers to bypass brute force protection mechanisms via crafted web requests.

Cross Site Scripting vulnerability found in Netgate pfSense 2.4.4 and ACME package v.0.6.3 allows attackers to execute arbitrary code via the RootFolder field of acmecertificates.php.

A cross-site scripting (XSS) vulnerability in pfsense v2.5.2 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the $pconfig variable at interfacesgroupsedit.php.

Netgate pfSense CE 2.7.2 allows code execution by using the module installer with a backup file with a serialized PHP object containing the postrebootcommands property. NOTE: the Supplier disputes this because this installer is only available to admins and they are intentionally allowed to execute PHP code.

pfSense through 2.3.4 through 2.4.4-p3 allows Remote Code Injection via a methodCall XML document with a pfsense.execphp call containing shell metacharacters in a parameter value.

An authenticated command injection vulnerability exists in statusinterfaces.php via dhcprelinquishlease() in pfSense before 2.4.4 due to its passing user input from the $POST parameters "ifdescr" and "ipv" to a shell without escaping the contents of the variables. This allows an authenticated WebGUI user with privileges for the affected page to execute commands in the context of the root user when submitting a request to relinquish a DHCP lease for an interface which is configured to obtain its address via DHCP.

Netgate pfSense CE (prior to 2.8.0 beta release) and corresponding Plus builds are vulnerable to command injection in the OpenVPN widget due to improper sanitization of user-supplied input to the OpenVPN management interface. An authenticated attacker can exploit this vulnerability by injecting arbitrary OpenVPN management commands via the remipp parameter.

This vulnerability allows remote attackers to create arbitrary files on affected installations of Netgate pfSense. Authentication is required to exploit this vulnerability. The specific flaw exists within the Suricata package. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to create files in the context of root.

Netgate pfSense CE Suricata Path Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to create arbitrary files on affected installations of Netgate pfSense. Authentication is required to exploit this vulnerability.

The specific flaw exists within the Suricata package. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to create files in the context of root. Was ZDI-CAN-28085.

diagcommand.php in pfSense 2.4.4-p3 allows CSRF via the txtCommand or txtRecallBuffer field, as demonstrated by executing OS commands. This occurs because csrfcallback() produces a "CSRF token expired" error and a Try Again button when a CSRF token is missing.

A command injection vulnerability in the function restorerrddata() of Netgate pfSense v2.7.0 allows authenticated attackers to execute arbitrary commands via manipulating the contents of an XML file supplied to the component config.xml.

pfSense versions 2.4.1 and lower are vulnerable to clickjacking attacks in the CSRF error page resulting in privileged execution of arbitrary code, because the error detection occurs before an X-Frame-Options header is set. This is fixed in 2.4.2-RELEASE. OPNsense, a 2015 fork of pfSense, was not vulnerable since version 16.1.16 released on June 06, 2016. The unprotected web form was removed from the code during an internal security audit under "possibly insecure" suspicions.

Improper input validation vulnerability in pfSense CE and pfSense Plus (pfSense CE software versions prior to 2.6.0 and pfSense Plus software versions prior to 22.01) allows a remote attacker with the privilege to change OpenVPN client or server settings to execute an arbitrary command.

Improper access control vulnerability in pfSense CE and pfSense Plus (pfSense CE software versions prior to 2.6.0 and pfSense Plus software versions prior to 22.01) allows a remote attacker with the privilege to change NTP GPS settings to rewrite existing files on the file system, which may result in arbitrary command execution.

An issue in Netgate pfSense v.2.7.0 allows a remote attacker to execute arbitrary code via a crafted request to the interfacesgifedit.php and interfacesgreedit.php components.

An issue in Netgate pfSense Plus v.23.05.1 and before and pfSense CE v.2.7.0 allows a remote attacker to execute arbitrary code via a crafted request to the packetcapture.php file.

NETGATE Data Backup 3.0.620 contains an unquoted service path vulnerability in its NGDatBckpSrv Windows service configuration. Attackers can exploit the unquoted path to inject and execute malicious code with LocalSystem privileges by placing executable files in specific directory locations.

Netgate AMITI Antivirus build 23.0.305 contains an unquoted service path vulnerability in the AmitiAvSrv and AmitiAntivirusHealth services that allows local attackers to escalate privileges. Attackers can place a malicious executable in the unquoted service path and trigger service restart or system reboot to execute code with LocalSystem privileges.

NETGATE Registry Cleaner build 16.0.205 contains an unquoted service path vulnerability in the NGRegClnSrv service that allows local attackers to escalate privileges by exploiting the service binary path. Attackers can place a malicious executable in the unquoted path and trigger service restart or system reboot to execute code with LocalSystem privileges.

Integer overflow in FreeBSD before 8.4 p24, 9.x before 9.3 p10. 10.0 before p18, and 10.1 before p6 allows remote attackers to cause a denial of service (crash) via a crafted IGMP packet, which triggers an incorrect size calculation and allocation of insufficient memory.

In pfSense 2.4.41, blocking of source IP addresses on the basis of failed HTTPS authentication is inconsistent with blocking of source IP addresses on the basis of failed SSH authentication (the behavior does not match the sshguard documentation), which might make it easier for attackers to bypass intended access restrictions.

The expiretable configuration in pfSense 2.4.41 establishes block durations that are incompatible with the block durations implemented by sshguard, which might make it easier for attackers to bypass intended access restrictions.

An exploitable command injection vulnerability exists in the way Netgate pfSense CE 2.4.4-RELEASE processes the parameters of a specific POST request. The attacker can exploit this and gain the ability to execute arbitrary commands on the system. An attacker needs to be able to send authenticated POST requests to the administration web interface. Command injection is possible in the powerdnormalmode parameter.
