Cacti: User Enumeration via Error Messages

Cacti is an open source performance and fault management framework. Prior to version 1.2.31, a User Enumeration vulnerability allows an attacker to identify valid usernames on the Cacti service. When a user attempts to log in, the application returns slightly different error messages depending on whether the provided username exists in the system. When username exists on Cacti, in the response, they see Access Denied! Login failed. When it does not exist on Cacti, they see Access Denied! Login Failed. The only difference between the responses is the capitalization of the letter "f" in the word failed. This issue has been patched in version 1.

Cacti: Authenticated RCE on Data Input

Cacti is an open source performance and fault management framework. Prior to version 1.2.31, the prior blocklist ([;&| `$\\n\r]) omitted single-quote, double-quote, redirect operators, subshell parens and braces. An authenticated admin could save an input_string` containing single-quote, redirect operator, or subshell parens, and pass the check. This issue has been patched in version 1.2.31.

Cacti: Authenticated Stored 2nd-Order SQL Injection in automation_tree_rule_items.field (incomplete-fix variant of CVE-2024-31460 / CVE-2025-24368)

Cacti is an open source performance and fault management framework. From version 1.2.27 to before version 1.2.31, Cacti contains an authenticated stored second-order SQL injection in the automation tree rule item handler. A user holding the Automation realm (default General Administration role) can persist an arbitrary SQL fragment in the automation_tree_rule_items.field column. The fragment is later concatenated directly into a SELECT ... AS source FROM ... clause in lib/api_automation.php :: create_all_header_nodes() and executed when an administrator triggers automation via the standard graphs.php?action=actions&drp_action=8 ("Apply Automa

Cacti sanitize_sql_column() Regex Allowlist Permits SQL Time-Delay Functions Leading to Blind SQL Injection

Cacti's sanitize_sql_column (lib/functions.php) sanitizes user-supplied ORDER BY column names using the regex . Because this allowlist retains letters, digits, underscore, parentheses, and dot (intended to support expressions like COUNT(id) and table.column), a payload such as passes through completely unmodified.

Cacti: Package Import Signature Validation Bypass Allows Self-Signed Packages

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have a package import signature validation bypass allows which allows self-signed packages. This issue has been fixed in version 1.2.31.

Cacti: Arbitrary File Read via Path Traversal in Report `format_file` Parameter

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Path Traversal through the Report format_file Parameter, causing arbitrary file read. This vulnerability occurs in two stages. In the first stage (stored injection), lib/html_reports.php at line 283 stores $save['format_file'] = $post['format_file'] directly into the database without any validation. In the second stage (file read), lib/reports.php at line 667 concatenates CACTI_PATH_FORMATS . '/' . $format_file, and line 670 then calls file($format_file), reading arbitrary files from the filesystem. This issue has been fixed in v

Cacti: SQL Injection in managers.php

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have SQL Injection through unsanitized unserialize+implode in managers.php. At line 756 of managers.php, the application assigns $selected_items by calling cacti_unserialize(stripslashes(gnrv('selected_graphs_array'))). The cacti_unserialize() function calls unserialize() with allowed_classes set to false, which prevents object injection but still allows arbitrary string arrays to be deserialized. Then, at lines 760 to 766, the deserialized array values are passed directly into db_execute('DELETE FROM snmpagent_managers WHERE id IN (' . implode('

Cacti: Session Fixation via missing session_regenerate_id() after login

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have missing session_regenerate_id() after login, leading to Session Fixation. session_regenerate_id() is NOT called after successful login. The login flow at auth_login.php:203-207 directly sets $_SESSION[SESS_USER_ID] without rotating the session ID. The session cookie configuration is otherwise good (httponly=true, samesite=Strict, secure=true for HTTPS at include/global.php:513-537), but these do not prevent session fixation via same-site vectors. This issue has been fixed in version 1.2.31.

Cacti: Open Redirect via HTTP_REFERER substring check in auth_login_redirect

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Open Redirect through a substring check rather than a host check at str_contains($referer, CACTI_PATH_URL). When the user's login_opts == '1' (redirect to referer after login), the function used $_SERVER['HTTP_REFERER'] directly. An attacker could craft a referer such as https://evil.com/cacti/. Where CACTI_PATH_URL is /cacti/, the substring matches and the user is redirected to evil.com after login. The pre-existing validate_redirect_url() helper at lib/html_utility.php performed proper validation but was not invoked from auth_log

Cacti: Command Injection via escape_command() no-op in RRDtool execution

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Command Injection due to lack of sanitization in the escape_command() function. The escape_command() function at lib/rrd.php is a no-op: it returns $command unchanged. The command line built by rrdtool_function_graph() is passed through this function and then to shell_exec($full_commandline). The risk is in __rrd_execute() where text_format values from graph templates (which may contain host variable substitutions) reach shell_exec without adequate escaping. This issue has been addressed in version 1.2.31.

Cacti: Stored SQL Injection via graph_name_regexp in Reports feature

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have a Stored SQL Injection vulnerability through graph_name_regexp in the Reports feature. This issue has been fixed in version 1.2.31.

Cacti has SQL Injection via rfilter parameter in RLIKE clauses

Cacti is an open source performance and fault management framework. In versions 1.2.30 and prior, the rfilter request parameter is retrieved via the raw accessor grv() (rather than gfrv() with FILTER_VALIDATE_IS_REGEX validation) and concatenated directly into RLIKE SQL clauses in lib/html_graph.php and lib/html_tree.php, which are reachable pre-authentication through graph_view.php on installations with guest graph viewing enabled. Because the unbalanced-quote payload bypasses the regex validation that would otherwise reject it, an unauthenticated attacker can inject arbitrary SQL to compromise the confidentiality, integrity, and availabilit

Cacti has Pre-Authentication SQL Injection via unanchored FILTER_VALIDATE_REGEXP in graph_view.php

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have pre-authentication SQL Injection via unanchored FILTER_VALIDATE_REGEXP in graph_view.php. This issue has been fixed in version 1.2.31.

Cacti: Unauthenticated RCE on Graph Image

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior have unauthenticated LFI through graph_theme and rrdtool IPC serialization hardening. This issue has been resolved in version 1.2.31.

Cacti: Reflected XSS via tab parameter in auth_profile.php JavaScript context

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Reflected XSS via tab parameter in the auth_profile.php JavaScript context. This issue has been fixed in version 1.2.31.

Cacti: Path Traversal via filename parameter in package_import.php

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Path Traversal via filename parameter in package_import.php. This issue has been fixed in version 1.2.31.

Cacti has a Reflected XSS Vulnerability via html_auth_footer

Cacti is an open source performance and fault management framework. Versions 1.2.30 and below contain a Reflected XSS vulnerability in the html_auth_footer. This issue has been fixed in version 1.2.31.

Cacti: RRDtool metric shift via LC_NUMERIC locale comma decimal formatting

Cacti is an open source performance and fault management framework. In versions 1.2.30 and below, the locale-dependent decimal formatting in rrdtool_function_update() can corrupt RRDtool metric values. The rrdtool_function_update() function checks metric values with is_numeric() and concatenates them into the RRDtool update command via PHP string interpolation. PHP's string cast of floats is locale-sensitive: if LC_NUMERIC uses comma as decimal separator (e.g., de_DE), a value of 1.5 becomes "1,5". RRDtool expects . as decimal separator, causing metric data to shift into wrong columns or be silently dropped. No setlocale() reset is present in

Cacti: Pre-authentication SQL injection via rfilter RLIKE clause in graph_view.php

Cacti is an open source performance and fault management framework. In versions 1.2.30 and prior, the rfilter request variable was concatenated into a RLIKE SQL clause without sanitization. The endpoint does not require authentication (graph viewing supports guest access via the configured guest user), so the SQLi was reachable pre-auth on installs with guest viewing enabled. This issue was fixed in version 1.2.31.

CVE-2025-45160

A HTML injection vulnerability exists in the file upload functionality of Cacti <= 1.2.29. When a file with an invalid format is uploaded, the application reflects the submitted filename back into an error popup without proper sanitization. As a result, attackers can inject arbitrary HTML elements (e.g., <h1>, <b>, <svg>) into the rendered page. NOTE: Multiple third-parties including the maintainer have stated that they cannot reproduce this issue after 1.2.27.
