etc/inc/certs.inc in the PKI implementation in pfSense before 2.0.1 creates each X.509 certificate with a true value for the CA basic constraint, which allows remote attackers to create sub-certificates for arbitrary subjects by leveraging the private key.

Cross-site scripting (XSS) vulnerability in status_rrd_graph.php in pfSense before 2.0.1 allows remote attackers to inject arbitrary web script or HTML via the style parameter.

Multiple cross-site scripting (XSS) vulnerabilities in the Snort package before 3.0.13 for pfSense through 2.1.4 allow remote attackers to inject arbitrary web script or HTML via (1) the eng parameter to snort_import_aliases.php or (2) unspecified variables to snort_select_alias.php.

Multiple cross-site scripting (XSS) vulnerabilities in suricata_select_alias.php in the Suricata package before 1.0.6 for pfSense through 2.1.4 allow remote attackers to inject arbitrary web script or HTML via unspecified variables.

Multiple open redirect vulnerabilities in the Snort package before 3.0.13 for pfSense through 2.1.4 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via (1) the referer parameter to snort_rules_flowbits.php or (2) the returl parameter to snort_select_alias.php.

Multiple open redirect vulnerabilities in the Suricata package before 1.0.6 for pfSense through 2.1.4 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via (1) the referer parameter to suricata_rules_flowbits.php or (2) the returl parameter to suricata_select_alias.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.

/usr/local/www/freeradius_view_config.php in the freeradius3 package before 0.15.7_3 for pfSense on FreeBSD allows a user with an XSS payload as password or username to execute arbitrary javascript code on a victim browser.

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.

A stored cross-site scripting (XSS) vulnerability was discovered in pfSense 2.4.5-p1 which allows an authenticated attacker to execute arbitrary web scripts via exploitation of the load_balancer_monitor.php function.

Cross-site scripting vulnerability in pfSense CE and pfSense Plus (pfSense CE software versions 2.5.2 and earlier, and pfSense Plus software versions 21.05 and earlier) allows a remote attacker to inject an arbitrary script via a malicious URL.

pfSense 2.5.0 allows XSS via the services_wol_edit.php Description field.

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 common protection mechanisms against command injection (i.e., the usage of the escapeshellarg function for the arguments) are used, it is still possible to inject sed-specific code and write an arbitrary file in an arbitrary location.

Directory traversal vulnerability in pfSense-pkg-WireGuard pfSense-pkg-WireGuard 0.1.5 versions prior to 0.1.5_4 and pfSense-pkg-WireGuard 0.1.6 versions prior to 0.1.6_1 allows a remote authenticated attacker to lead a pfSense user to view a file outside the public folder.

/usr/local/www/pkg.php in pfSense CE before 2.6.0 and pfSense Plus before 22.01 uses $_REQUEST['pkg_filter'] in a PHP echo call, causing XSS.

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.

pfSense v2.5.2 was discovered to contain a cross-site scripting (XSS) vulnerability in the browser.php component. This vulnerability allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into a file name.

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.

Pfsense CE version 2.6.0 is vulnerable to No rate limit which can lead to an attacker creating multiple malicious users in firewall.

An issue discovered in Pfsense CE version 2.6.0 allows attackers to compromise user accounts via weak password requirements.

An issue discovered in Pfsense CE version 2.6.0 allows attackers to change the password of any user without verification.

In pfSense CE /usr/local/www/haproxy/haproxy_stats.php, the value of the showsticktablecontent parameter is displayed after being read from HTTP GET requests. This can enable reflected cross-site scripting when the victim is authenticated.

In pfSense CE /usr/local/www/snort/snort_ip_reputation.php, the value of the iplist parameter is not sanitized of directory traversal-related characters/strings before being used to check if a file exists. While the contents of the file cannot be read, the server reveals whether a file exists, which allows an attacker to enumerate files on the target. The attacker must be authenticated with at least "WebCfg - Services: Snort package" permissions.

In pfSense CE /usr/local/www/status_traffic_totals.php, the value of the start-day parameter is not ensured to be a numeric value or sanitized of HTML-related characters/strings before being directly displayed in the input box. This value can be saved as the default value to be displayed to all users when visiting the Status Traffic Totals page, resulting in stored cross-site scripting. The attacker must be authenticated with at least "WebCfg - Status: Traffic Totals" permissions.

In pfSense CE /usr/local/www/suricata/suricata_filecheck.php, the value of the filehash parameter is directly displayed without sanitizing for HTML-related characters/strings. This can result in reflected cross-site scripting if the victim is authenticated.

In pfSense CE /suricata/suricata_ip_reputation.php, the value of the iplist parameter is not sanitized of directory traversal-related strings/characters. This value is directly used in a file existence check operation. While the contents of the file cannot be read, the server reveals whether the file exists, which enables an attacker to enumerate files on the target. The attacker must be authenticated with at least "WebCfg - Services: suricata package" permissions.

In pfSense CE /suricata/suricata_flow_stream.php, the value of the policy_name parameter is not sanitized of HTML-related strings/characters before being directly displayed. This can result in stored cross-site scripting. The attacker must be authenticated with at least "WebCfg - Services: suricata package" permissions.

In pfSense CE /suricata/suricata_app_parsers.php, the value of the policy_name parameter is not sanitized of HTML-related strings/characters before being directly displayed. This can result in stored cross-site scripting. The attacker must be authenticated with at least "WebCfg - Services: suricata package" permissions.

In Netgate pfSense CE 2.8.0, the "WebCfg - Diagnostics: Command" privilege allows reading arbitrary files via diag_command.php dlPath directory traversal. NOTE: the Supplier's perspective is that this is intended behavior for this privilege level, and that system administrators are informed through both the product documentation and UI.
