    Multiple security vulnerabilities were discovered in cacti, a web     interface for graphing of monitoring systems, which may result in     information disclosure, authentication bypass, or remote code execution.

    CVE-2020-8813

        Askar discovered that an authenticated guest user with the graph         real-time privilege could execute arbitrary code on a server running         Cacti, via shell meta-characters in a cookie.

    CVE-2020-23226

        Jing Chen discovered multiple Cross Site Scripting (XSS)         vulnerabilities in several pages, which can lead to information         disclosure.

    CVE-2020-25706

        joelister discovered an Cross Site Scripting (XSS) vulnerability in         templates_import.php, which can lead to information disclosure.

    CVE-2022-0730

        It has been discovered that Cacti authentication can be bypassed         when LDAP anonymous binding is enabled.

    CVE-2022-46169

        Stefan Schiller discovered a command injection vulnerability,         allowing an unauthenticated user to execute arbitrary code on a         server running Cacti, if a specific data source was selected (which         is likely the case on a production instance) for any monitored         device.

    For Debian 10 buster, these problems have been fixed in version     1.2.2+ds1-2+deb10u5.

    We recommend that you upgrade your cacti packages.

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-5298 advisory.

  - Under certain ldap conditions, Cacti authentication can be bypassed with certain credential types.
    (CVE-2022-0730)

  - 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. (CVE-2022-46169)

The remote Debian 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-2965 advisory.

    Multiple vulnerabilities were discovered in Cacti, a web interface for graphing of monitoring systems,     leading to authentication bypass and cross-site scripting (XSS). An attacker may get access to     unauthorized areas and impersonate other users, under certain conditions. CVE-2018-10060 Cacti has XSS     because it does not properly reject unintended characters, related to use of the sanitize_uri function in     lib/functions.php. CVE-2018-10061 Cacti has XSS because it makes certain htmlspecialchars calls without     the ENT_QUOTES flag (these calls occur when the html_escape function in lib/html.php is not used).
    CVE-2019-11025 No escaping occurs before printing out the value of the SNMP community string (SNMP     Options) in the View poller cache, leading to XSS. CVE-2020-7106 Cacti has stored XSS in multiple files 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). CVE-2020-13230 Disabling a user account does not immediately     invalidate any permissions granted to that account (e.g., permission to view logs). CVE-2020-23226     Multiple Cross Site Scripting (XSS) vulnerabilities exist in multiple files. CVE-2021-23225 Cacti allows     authenticated users with User Management permissions to inject arbitrary web script or HTML in the     new_username field during creation of a new user via Copy method at user_admin.php. CVE-2022-0730 Under     certain ldap conditions, Cacti authentication can be bypassed with certain credential types. For Debian 9     stretch, these problems have been fixed in version 0.8.8h+ds1-10+deb9u2. We recommend that you upgrade     your cacti packages.
