Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, some of the data stored in `automation_tree_rules_form_save()` function in `automation_tree_rules.php` is not thoroughly checked and is used to concatenate the HTML statement in `form_confirm()` function from `lib/html.php` , finally resulting in cross-site scripting. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Prior to 1.2.27, some of the data stored in `form_save()` function in `data_queries.php` is not thoroughly checked and is used to concatenate the HTML statement in `grow_right_pane_tree()` function from `lib/html.php` , finally resulting in cross-site scripting. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. A reflected cross-site scripting vulnerability on the 1.3.x DEV branch allows attackers to obtain cookies of administrator and other users and fake their login using obtained cookies. This issue is fixed in commit a38b9046e9772612fda847b46308f9391a49891e.

Cacti provides an operational monitoring and fault management framework. A command injection vulnerability on the 1.3.x DEV branch allows any unauthenticated user to execute arbitrary command on the server when `register_argc_argv` option of PHP is `On`. In `cmd_realtime.php` line 119, the `$poller_id` used as part of the command execution is sourced from `$_SERVER['argv']`, which can be controlled by URL when `register_argc_argv` option of PHP is `On`. And this option is `On` by default in many environments such as the main PHP Docker image for PHP. Commit 53e8014d1f082034e0646edc6286cde3800c683d contains a patch for the issue, but this commit was reverted in commit 99633903cad0de5ace636249de16f77e57a3c8fc.

Cacti provides an operational monitoring and fault management framework. Versions of Cacti prior to 1.2.27 contain a residual cross-site scripting vulnerability caused by an incomplete fix for CVE-2023-50250. `raise_message_javascript` from `lib/functions.php` now uses purify.js to fix CVE-2023-50250 (among others). However, it still generates the code out of unescaped PHP variables `$title` and `$header`. If those variables contain single quotes, they can be used to inject JavaScript code. An attacker exploiting this vulnerability could execute actions on behalf of other users. This ability to impersonate users could lead to unauthorized changes to settings. Version 1.2.27 fixes this issue.

Cacti provides an operational monitoring and fault management framework. Versions of Cacti prior to 1.2.27 are vulnerable to stored cross-site scripting, a type of cross-site scripting where malicious scripts are permanently stored on a target server and served to users who access a particular page. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Version 1.2.25 has a Blind SQL Injection (SQLi) vulnerability within the SNMP Notification Receivers feature in the file `‘managers.php’`. An authenticated attacker with the “Settings/Utilities” permission can send a crafted HTTP GET request to the endpoint `‘/cacti/managers.php’` with an SQLi payload in the `‘selected_graphs_array’` HTTP GET parameter. As of time of publication, no patched versions exist.

Cacti is an open source operational monitoring and fault management framework. A reflection cross-site scripting vulnerability was discovered in version 1.2.25. Attackers can exploit this vulnerability to perform actions on behalf of other users. The vulnerability is found in `templates_import.php.` When uploading an xml template file, if the XML file does not pass the check, the server will give a JavaScript pop-up prompt, which contains unfiltered xml template file name, resulting in XSS. An attacker exploiting this vulnerability could execute actions on behalf of other users. This ability to impersonate users could lead to unauthorized changes to settings. As of time of publication, no patched versions are available.

Cacti is an open source operational monitoring and fault management framework. The fix applied for CVE-2023-39515 in version 1.2.25 is incomplete as it enables an adversary to have a victim browser execute malicious code when a victim user hovers their mouse over the malicious data source path in `data_debug.php`. To perform the cross-site scripting attack, the adversary needs to be an authorized cacti user with the following permissions: `General Administration>Sites/Devices/Data`. The victim of this attack could be any account with permissions to view `http://<HOST>/cacti/data_debug.php`. As of time of publication, no complete fix has been included in Cacti.

Cacti is a robust performance and fault management framework and a frontend to RRDTool - a Time Series Database (TSDB). A vulnerability in versions prior to 1.2.27 bypasses an earlier fix for CVE-2023-39360, therefore leading to a DOM XSS attack. Exploitation of the vulnerability is possible for an authorized user. The vulnerable component is the `graphs_new.php`. The impact of the vulnerability is execution of arbitrary JavaScript code in the attacked user's browser. This issue has been patched in version 1.2.27.
