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.

diag_routes.php in pfSense 2.5.2 allows sed data injection. Authenticated users are intended to be able to view data about the routes set in the firewall. The data is retrieved by executing the netstat utility, and then its output is parsed via the sed utility. Although the…

pfSense pfBlockerNG through 2.1.4_27 allows remote attackers to execute arbitrary OS commands as root via the HTTP Host header, a different vulnerability than CVE-2022-31814.

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

Netgate pfSense CE 2.8.0 allows code execution in the XMLRPC API via pfsense.exec_php. 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 discovered in Pfsense CE version 2.6.0 allows attackers to compromise user accounts via weak password requirements.

Apcupsd 0.3.91_5, as used in pfSense through 2.4.4-RELEASE-p3 and other products, has an Arbitrary Command Execution issue in apcupsd_status.php.

pfSense before 2.3 allows remote authenticated users to execute arbitrary OS commands via a '|' character in the status_rrd_graph_img.php graph parameter, related to _rrd_graph_img.php.

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…

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 post_reboot_commands property. NOTE: the Supplier disputes this because this installer is only available to admins and they are…

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…

An authenticated command injection vulnerability exists in status_interfaces.php via dhcp_relinquish_lease() 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…

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…

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 file_get_contents or file_put_contents.

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

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…

Directory Traversal vulnerability found in Pfsense v.2.1.3 and Pfsense Suricata v.1.4.6 pkg v.1.0.1 allows a remote attacker to obtain sensitive information via the file parameter to suricata/suricata_logs_browser.php.

In pfSense 2.4.4_1, 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…

The expiretable configuration in pfSense 2.4.4_1 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 issue discovered in Pfsense CE version 2.6.0 allows attackers to change the password of any user without verification.
