Cacti Cacti 0.8.1

Cacti is an open source performance and fault management framework. Due to a flaw in multi-line SNMP result parser, authenticated users can inject malformed OIDs in the response. When processed by ss_net_snmp_disk_io() or ss_net_snmp_disk_bytes(), a part of each OID will be used as a key in an array that is used as part of a system command, causing a command execution vulnerability. This vulnerability is fixed in 1.2.29.

Cacti is an open source performance and fault management framework. Cacti has a SQL injection vulnerability in the template function of host_templates.php using the graph_template parameter. This vulnerability is fixed in 1.2.29.

Cacti is an open source performance and fault management framework. Cacti has a SQL injection vulnerability in the get_discovery_results function of automation_devices.php using the network parameter. This vulnerability is fixed in 1.2.29.

Cacti is an open source performance and fault management framework. Prior to 1.2.29, an administrator can change the `Poller Standard Error Log Path` parameter in either Installation Step 5 or in Configuration->Settings->Paths tab to a local file inside the server. Then simply going to Logs tab and selecting the name of the local file will show its content on the web UI. This vulnerability is fixed in 1.2.29.

Cacti is an open source performance and fault management framework. The `title` parameter is not properly sanitized when saving external links in links.php . Morever, the said title parameter is stored in the database and reflected back to user in index.php, finally leading to stored XSS. Users with the privilege to create external links can manipulate the `title` parameter in the http post request while creating external links to perform stored XSS attacks. The vulnerability known as XSS (Cross-Site Scripting) occurs when an application allows untrusted user input to be displayed on a web page without proper validation or escaping. This issue has been addressed in release version 1.2.28. All users are advised to upgrade. There are no known workarounds for this vulnerability.

Cacti is an open source performance and fault management framework. An admin user can create a device with a malicious hostname containing php code and repeat the installation process (completing only step 5 of the installation process is enough, no need to complete the steps before or after it) to use a php file as the cacti log file. After having the malicious hostname end up in the logs (log poisoning), one can simply go to the log file url to execute commands to achieve RCE. This issue has been addressed in version 1.2.28 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Cacti is an open source performance and fault management framework. The `fileurl` parameter is not properly sanitized when saving external links in `links.php` . Morever, the said fileurl is placed in some html code which is passed to the `print` function in `link.php` and `index.php`, finally leading to stored XSS. Users with the privilege to create external links can manipulate the `fileurl` parameter in the http post request while creating external links to perform stored XSS attacks. The vulnerability known as XSS (Cross-Site Scripting) occurs when an application allows untrusted user input to be displayed on a web page without proper validation or escaping. This issue has been addressed in release version 1.2.28. All users are advised to upgrade. There are no known workarounds for this issue.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, Cacti calls `compat_password_hash` when users set their password. `compat_password_hash` use `password_hash` if there is it, else use `md5`. When verifying password, it calls `compat_password_verify`. In `compat_password_verify`, `password_verify` is called if there is it, else use `md5`. `password_verify` and `password_hash` are supported on PHP < 5.5.0, following PHP manual. The vulnerability is in `compat_password_verify`. Md5-hashed user input is compared with correct password in database by `$md5 == $hash`. It is a loose comparison, not `===`. It is a type juggling vulnerability. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, some of the data stored in `automation_tree_rules.php` is not thoroughly checked and is used to concatenate the SQL statement in `create_all_header_nodes()` function from `lib/api_automation.php` , finally resulting in SQL injection. Using SQL based secondary injection technology, attackers can modify the contents of the Cacti database, and based on the modified content, it may be possible to achieve further impact, such as arbitrary file reading, and even remote code execution through arbitrary file writing. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, there is a file inclusion issue in the `lib/plugin.php` file. Combined with SQL injection vulnerabilities, remote code execution can be implemented. There is a file inclusion issue with the `api_plugin_hook()` function in the `lib/plugin.php` file, which reads the plugin_hooks and plugin_config tables in database. The read data is directly used to concatenate the file path which is used for file inclusion. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, some of the data stored in `form_save()` function in `graph_template_inputs.php` is not thoroughly checked and is used to concatenate the SQL statement in `draw_nontemplated_fields_graph_item()` function from `lib/html_form_templates.php` , finally resulting in SQL injection. Version 1.2.27 contains a patch for the issue.

Cacti provides an operational monitoring and fault management framework. Prior to version 1.2.27, a SQL injection vulnerability in `automation_get_new_graphs_sql` function of `api_automation.php` allows authenticated users to exploit these SQL injection vulnerabilities to perform privilege escalation and remote code execution. In `api_automation.php` line 856, the `get_request_var('filter')` is being concatenated into the SQL statement without any sanitization. In `api_automation.php` line 717, The filter of `'filter'` is `FILTER_DEFAULT`, which means there is no filter for it. Version 1.2.27 contains a patch for the issue.

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. 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. Prior to version 1.2.27, an arbitrary file write vulnerability, exploitable through the "Package Import" feature, allows authenticated users having the "Import Templates" permission to execute arbitrary PHP code on the web server. The vulnerability is located within the `import_package()` function defined into the `/lib/import.php` script. The function blindly trusts the filename and file content provided within the XML data, and writes such files into the Cacti base path (or even outside, since path traversal sequences are not filtered). This can be exploited to write or overwrite arbitrary files on the web server, leading to execution of arbitrary PHP code or other security impacts. Version 1.2.27 contains a patch for this issue.

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:///cacti/data_debug.php`. As of time of publication, no complete fix has been included in Cacti.

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 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. These data will be viewed by administrative _cacti_ accounts and execute JavaScript code in the victim's browser at view-time. The script under `reports_admin.php` displays reporting information about graphs, devices, data sources etc. _CENSUS_ found that an adversary that is able to configure a malicious device name, related to a graph attached to a report, can deploy a stored XSS attack against any super user who has privileges of viewing the `reports_admin.php` page, such as administrative accounts. A user that possesses the _General Administration>Sites/Devices/Data_ permissions can configure the device names in _cacti_. This configuration occurs through `http:///cacti/host.php`, while the rendered malicious payload is exhibited at `http:///cacti/reports_admin.php` when the a graph with the maliciously altered device name is linked to the report. This issue has been addressed in version 1.2.25. Users are advised to upgrade. Users unable to upgrade should manually filter HTML output.
