Cacti is an open source operational monitoring and fault management framework. In Cacti 1.2.24, users with console access can be redirected to an arbitrary website after a change password performed via a specifically crafted URL. The `auth_changepassword.php` file accepts `ref` as a URL parameter and reflects it in the form used to perform the change password. It's value is used to perform a redirect via `header` PHP function. A user can be tricked in performing the change password operation, e.g., via a phishing message, and then interacting with the malicious website where the redirection has been performed, e.g., downloading malwares, providing credentials, etc. This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Cacti is an open source operational monitoring and fault management framework. Affected versions are subject to a Stored Cross-Site-Scripting (XSS) Vulnerability which allows an authenticated user to poison data stored in the _cacti_'s database.

Cacti is an open source platform which provides a robust and extensible operational monitoring and fault management framework for users. In affected versions a command injection vulnerability allows an unauthenticated user to execute arbitrary code on a server running Cacti, if a specific data source was selected for any monitored device. The vulnerability resides in the `remote_agent.php` file. This file can be accessed without authentication. This function retrieves the IP address of the client via `get_client_addr` and resolves this IP address to the corresponding hostname via `gethostbyaddr`. After this, it is verified that an entry within the `poller` table exists, where the hostname corresponds to the resolved hostname. If such an entry was found, the function returns `true` and the client is authorized. This authorization can be bypassed due to the implementation of the `get_client_addr` function. The function is defined in the file `lib/functions.php` and checks serval `$_SERVER` variables to determine the IP address of the client. The variables beginning with `HTTP_` can be arbitrarily set by an attacker. Since there is a default entry in the `poller` table with the hostname of the server running Cacti, an attacker can bypass the authentication e.g. by providing the header `Forwarded-For: <TARGETIP>`. This way the function `get_client_addr` returns the IP address of the server running Cacti. The following call to `gethostbyaddr` will resolve this IP address to the hostname of the server, which will pass the `poller` hostname check because of the default entry. After the authorization of the `remote_agent.php` file is bypassed, an attacker can trigger different actions. One of these actions is called `polldata`. The called function `poll_for_data` retrieves a few request parameters and loads the corresponding `poller_item` entries from the database. If the `action` of a `poller_item` equals `POLLER_ACTION_SCRIPT_PHP`, the function `proc_open` is used to execute a PHP script. The attacker-controlled parameter `$poller_id` is retrieved via the function `get_nfilter_request_var`, which allows arbitrary strings. This variable is later inserted into the string passed to `proc_open`, which leads to a command injection vulnerability. By e.g. providing the `poller_id=;id` the `id` command is executed. In order to reach the vulnerable call, the attacker must provide a `host_id` and `local_data_id`, where the `action` of the corresponding `poller_item` is set to `POLLER_ACTION_SCRIPT_PHP`. Both of these ids (`host_id` and `local_data_id`) can easily be bruteforced. The only requirement is that a `poller_item` with an `POLLER_ACTION_SCRIPT_PHP` action exists. This is very likely on a productive instance because this action is added by some predefined templates like `Device - Uptime` or `Device - Polling Time`. This command injection vulnerability allows an unauthenticated user to execute arbitrary commands if a `poller_item` with the `action` type `POLLER_ACTION_SCRIPT_PHP` (`2`) is configured. The authorization bypass should be prevented by not allowing an attacker to make `get_client_addr` (file `lib/functions.php`) return an arbitrary IP address. This could be done by not honoring the `HTTP_...` `$_SERVER` variables. If these should be kept for compatibility reasons it should at least be prevented to fake the IP address of the server running Cacti. This vulnerability has been addressed in both the 1.2.x and 1.3.x release branches with `1.2.23` being the first release containing the patch.

Under certain ldap conditions, Cacti authentication can be bypassed with certain credential types.

graph_realtime.php in Cacti 1.2.8 allows remote attackers to execute arbitrary OS commands via shell metacharacters in a cookie, if a guest user has the graph real-time privilege.

Cacti through 1.2.7 is affected by a graphs.php?template_id= SQL injection vulnerability affecting how template identifiers are handled when a string and id composite value are used to identify the template type and id. An authenticated attacker can exploit this to extract data from the database, or an unauthenticated remote attacker could exploit this via Cross-Site Request Forgery.

Cacti 1.2.8 allows Remote Code Execution (by privileged users) via shell metacharacters in the Performance Boost Debug Log field of poller_automation.php. OS commands are executed when a new poller cycle begins. The attacker must be authenticated, and must have access to modify the Performance Settings of the product.

Cacti 1.2.8 has stored XSS in data_sources.php, color_templates_item.php, graphs.php, graph_items.php, lib/api_automation.php, user_admin.php, and user_group_admin.php, as demonstrated by the description parameter in data_sources.php (a raw string from the database that is displayed by $header to trigger the XSS).

data_input.php in Cacti 1.2.8 allows remote code execution via a crafted Input String to Data Collection -> Data Input Methods -> Unix -> Ping Host. NOTE: the vendor has stated "This is a false alarm.

Cacti through 1.2.7 is affected by multiple instances of lib/functions.php unsafe deserialization of user-controlled data to populate arrays. An authenticated attacker could use this to influence object data values and control actions taken by Cacti or potentially cause memory corruption in the PHP module.

In Cacti through 1.2.6, authenticated users may bypass authorization checks (for viewing a graph) via a direct graph_json.php request with a modified local_graph_id parameter.

In clearFilter() in utilities.php in Cacti before 1.2.3, no escaping occurs before printing out the value of the SNMP community string (SNMP Options) in the View poller cache, leading to XSS.
