Cacti: Security Vulnerabilities
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 availability of the database. This advisory is similar to GHSA-69gg-mjfm-jjpc. This issue has been fixed in version 1.2.31.

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.

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 the update path. This causes a data integrity issue, but is not remotely exploitable; it requires server locale misconfiguration. The issue has been fixed in version 1.2.31.

Cacti is an open source performance and fault management framework. Prior to 1.2.29, there is an input-validation flaw in the SNMP device configuration functionality. An authenticated Cacti user can supply crafted SNMP community strings containing control characters (including newlines) that are accepted, stored verbatim in the database, and later embedded into backend SNMP operations. In environments where downstream SNMP tooling or wrappers interpret newline-separated tokens as command boundaries, this can lead to unintended command execution with the privileges of the Cacti process. This vulnerability is fixed in 1.2.29.

Cacti versions prior to 0.8.6-d contain a remote command execution vulnerability in the graph_view.php script. An authenticated user can inject arbitrary shell commands via the graph_start GET parameter, which is improperly handled during graph rendering. This flaw allows attackers to execute commands on the underlying operating system with the privileges of the web server process, potentially compromising system integrity.

Cacti through 1.2.29 allows SQL injection in the template function in host_templates.php via the graph_template parameter. NOTE: this issue exists because of an incomplete fix for CVE-2024-54146.

Cacti is an open source performance and fault management framework. An authenticated Cacti user can abuse graph creation and graph template functionality to create arbitrary PHP scripts in the web root of the application, leading to remote code execution on the server. This vulnerability is fixed in 1.2.29.

Cacti is an open source performance and fault management framework. Some of the data stored in automation_tree_rules.php is not thoroughly checked and is used to concatenate the SQL statement in build_rule_item_filter() function from lib/api_automation.php, resulting in SQL injection. This vulnerability is fixed in 1.2.29.
