CVE-2023-51448 overview
The Black Duck Cybersecurity Research Center (CyRC) has discovered CVE-2023-51448, a blind SQL injection (SQLi) vulnerability in Cacti.
Cacti is a performance and fault management framework written in PHP. It uses a variety of data collection methods to populate an RRDTool-based time series database (TSDB) with performance data, and offers a web user interface to view this performance data in graphs. Cacti is easily extensible for custom needs via its plugin system.
Due to insufficient sanitization when parsing the deserialized result of the ‘selected_graphs_array’ parameter, a crafted payload may trigger SQLi when the result is concatenated with a raw SQL query. Using a blind SQLi technique, an attacker can disclose Cacti database contents or trigger remote code execution (RCE).
CVE-2023-51448 exploitation
An attacker authenticated with any account that possesses the “Settings/Utilities” permission can send a crafted HTTP GET request to the endpoint ‘/managers.php’ with an SQLi payload in the ‘selected_graphs_array’ HTTP GET parameter to trigger the vulnerability.
Affected software
Cacti version 1.2.25
Impact
Exploitation of this vulnerability would allow an attacker to disclose the entire contents of the Cacti database. It may also be escalated to RCE, as demonstrated with CVE-2023-49084.
