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.

pfSense pfBlockerNG through 2.1.427 allows remote attackers to execute arbitrary OS commands as root via the HTTP Host header, a different vulnerability than CVE-2022-31814.

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.

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

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

diagroutes.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.

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.

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.

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/suricatalogsbrowser.php.

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

In Netgate pfSense CE 2.8.0, the "WebCfg - Diagnostics: Command" privilege allows reading arbitrary files via diagcommand.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.

Directory traversal vulnerability in pfSense-pkg-WireGuard pfSense-pkg-WireGuard 0.1.5 versions prior to 0.1.54 and pfSense-pkg-WireGuard 0.1.6 versions prior to 0.1.61 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['pkgfilter'] in a PHP echo call, causing XSS.

/usr/local/www/freeradiusviewconfig.php in the freeradius3 package before 0.15.73 for pfSense on FreeBSD allows a user with an XSS payload as password or username to execute arbitrary javascript code on a victim browser.

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

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 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.

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 suricatarulesflowbits.php or (2) the returl parameter to suricataselectalias.php.

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 snortrulesflowbits.php or (2) the returl parameter to snortselectalias.php.

In pfSense CE /usr/local/www/statustraffictotals.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 /suricata/suricataflowstream.php, the value of the policyname 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/suricataappparsers.php, the value of the policyname 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.

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 loadbalancermonitor.php function.

Cross Site Scripting (XSS) vulnerability in Netgate pfSense v.2.7.0 allows a remote attacker to gain privileges via a crafted URL to the getserviceproviders.php page.

Cross Site Scripting (XSS) vulnerability in Netgate pfSense v.2.7.0 allows a remote attacker to gain privileges via a crafted url to the statuslogsfilterdynamic.php page.

In pfSense CE /usr/local/www/snort/snortipreputation.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 /suricata/suricataipreputation.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 /usr/local/www/suricata/suricatafilecheck.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.

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