spikekill.php in Cacti before 1.1.16 might allow remote attackers to execute arbitrary code via the avgnan, outlier-start, or outlier-end parameter.

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.

Cacti 0.8.7e and earlier allows remote authenticated administrators to gain privileges by modifying the "Data Input Method" for the "Linux - Get Memory Usage" setting to contain arbitrary commands.

Cacti before 1.0.0 allows remote authenticated users to conduct PHP object injection attacks and execute arbitrary PHP code via a crafted serialized object, related to calling unserialize(stripslashes()).

SQL injection vulnerability in the host_new_graphs function in graphs_new.php in Cacti 0.8.8f and earlier allows remote authenticated users to execute arbitrary SQL commands via the cg_g parameter in a save action.

auth_login.php in Cacti before 0.8.8g allows remote authenticated users who use web authentication to bypass intended access restrictions by logging in as a user not in the cacti database.

SQL injection vulnerability in tree.php in Cacti 0.8.8g and earlier allows remote authenticated users to execute arbitrary SQL commands via the parent_id parameter in an item_edit action.

SQL injection vulnerability in graph_view.php in Cacti 0.8.8.g allows remote authenticated users to execute arbitrary SQL commands via the host_group_data parameter.

auth_login.php in Cacti before 1.0.0 allows remote authenticated users who use web authentication to bypass intended access restrictions by logging in as a user not in the cacti database, because the guest user is not considered. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-2313.

Cacti is an open source operational monitoring and fault management framework. An authenticated SQL injection vulnerability was discovered which allows authenticated users to perform privilege escalation and remote code execution. The vulnerability resides in the `reports_user.php` file. In `ajax_get_branches`, the `tree_id` parameter is passed to the `reports_get_branch_select` function without any validation. 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. An authenticated SQL injection vulnerability was discovered which allows authenticated users to perform privilege escalation and remote code execution. The vulnerability resides in the `graphs.php` file. When dealing with the cases of ajax_hosts and ajax_hosts_noany, if the `site_id` parameter is greater than 0, it is directly reflected in the WHERE clause of the SQL statement. This creates an SQL injection vulnerability. This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Cacti provides an operational monitoring and fault management framework. In versions 1.2.25 and prior, it is possible to execute arbitrary SQL code through the `pollers.php` script. An authorized user may be able to execute arbitrary SQL code. The vulnerable component is the `pollers.php`. Impact of the vulnerability - arbitrary SQL code execution. As of time of publication, a patch does not appear to exist.

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.

Cacti is an open source operational monitoring and fault management framework. Affected versions are subject to a privilege escalation vulnerability. A low-privileged OS user with access to a Windows host where Cacti is installed can create arbitrary PHP files in a web document directory. The user can then execute the PHP files under the security context of SYSTEM. This allows an attacker to escalate privilege from a normal user account to SYSTEM. This issue has been addressed in version 1.2.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Multiple SQL injection vulnerabilities in Cacti 0.8.7 before 0.8.7b and 0.8.6 before 0.8.6k allow remote authenticated users to execute arbitrary SQL commands via the (1) graph_list parameter to graph_view.php, (2) leaf_id and id parameters to tree.php, (3) local_graph_id parameter to graph_xport.php, and (4) login_username parameter to index.php/login.
