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.

The pfSense REST API package is an unofficial, open-source REST and GraphQL API for pfSense CE and pfSense Plus firewalls. A privilege escalation vulnerability in pfSense-pkg-RESTAPI prior to version 2.9.0 allows authenticated accounts holding the dedicated settings sync permission to modify REST API configuration secrets. This enables a non-administrative user to elevate their privileges to a full administrator. pfSense-pkg-RESTAPI 2.9.0 patches the issue. Access to the HA settings sync endpoint now strictly requires full administrative privileges (page-all). The sub-administrative sync privilege has been removed in versions v2.9.0 and later. In addition to correcting the access control boundary, version 2.9.0 includes the following hardening measures: opt-in default and format and validation modernization. As a workaround, one may mitigate exposure by taking either or all of the following steps. Revoke Scoped Permissions: Remove the api-v2-system-restapi-settings-sync-post privilege from all non-administrative users. Apply ACLs: Configure REST API Access Control Lists (ACLs) and/or firewall rules to restrict access to API endpoints exclusively to trusted administrator and HA peer IP addresses.

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.

Netgate pfSense CE 2.7.0 through 2.9.0 contains an OS command injection vulnerability that allows authenticated users with QinQ edit privilege to run commands by storing an unvalidated parent interface name. Attackers can save a crafted 'if' value, then edit the QinQ entry so it is interpolated into ifconfig shell commands, executing commands as root.

Netgate pfSense CE through 2.9.0 contains an OS command injection vulnerability that allows authenticated users to execute commands as root by supplying a crafted wireless parent interface name. Attackers with limited Wireless Edit or Interface Assignments privileges can submit values like ath0;<cmd> via interfaceswirelessedit.php or interfacesassign.php, which interfacewirelessclone() interpolates unescaped into an ifconfig shell command.

Netgate pfSense CE through 2.9.0 contains an OS command injection vulnerability that allows authenticated users with gateway edit privileges to execute commands as root by injecting shell metacharacters into an IPv6 link-local zone index. Attackers can set a gateway Monitor IP whose unvalidated zone carries a payload, which startdpinger() passes unescaped to the dpinger shell command when monitoring is applied.

Netgate pfSense CE 2.7.0 through 2.9.0 contains a configuration injection vulnerability that allows authenticated users with IPsec Mobile privileges to execute commands as root via the loginbanner field. Attackers can submit a single-line banner containing '}' to escape the unquoted strongswan.conf attr value and define charon.start-scripts entries that charon executes as root on restart.

Netgate pfSense CE 2.7.0 through 2.9.0 contains an OS command injection vulnerability that allows authenticated users with Traffic Shaper Limiters privileges to execute root commands by tampering with the limiter number field. Attackers can submit a malicious hidden 'number' value when editing a limiter, then delete it so deletequeue() passes the unquoted value to dnctl via /bin/sh as root.

Rejected reason: This CVE ID has been rejected because it does not describe a security vulnerability.

Netgate pfSense CE through 2.9.0 contains an OS command injection vulnerability that allows authenticated users with Virtual IP edit privileges to execute commands as root by storing an unvalidated CARP VHID. Attackers can supply a VHID containing shell metacharacters that executes via interfaceipaliasconfigure() ifconfig calls or getcarpinterfacestatus() when CARP status is rendered.

Netgate pfSense CE through 2.9.0 contains a php.ini injection vulnerability that allows authenticated users with General Setup privileges to inject directives by submitting an unvalidated timezone value. Attackers can embed a quote and newline to add autoprependfile pointing at /var/db/zoneinfo, executing PHP as root after php.ini is regenerated at boot or php-fpm restart.

Netgate pfSense CE through 2.9.0 contains a newline injection vulnerability in servicespppoeedit.php that allows privileged users to inject mpd.secret entries via unvalidated username POST fields. Attackers with the PPPoE Server Edit privilege can add a line whose secret begins with '!', making mpd5 run commands as root when a PPPoE client authenticates.

Rejected reason: This CVE ID has been rejected because it does not describe a security vulnerability.

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.

Netgate pfSense CE through 2.9.0 contains a local file read vulnerability that allows users with the Dynamic DNS client privilege to read files as root by setting a file:// custom Update URL in servicesdyndnsedit.php. Attackers can set a non-matching Result Match string so checkStatus() logs file contents such as /conf/config.xml or /etc/master.passwd to the system log.

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.
