Cacti Network Monitoring Tool Vulnerability Let Attackers Execute Remote Code

A critical security vulnerability has been identified in the Cacti network monitoring tool that could allow attackers to execute remote code on affected systems.

The vulnerability, detailed in the recent release of Cacti version 1.2.28, highlights the need for system administrators to pay immediate attention to this popular open-source software.

Remote Code Execution via Log Poisoning

The most alarming issue disclosed in the latest Cacti update is a Remote Code Execution (RCE) vulnerability, tracked as security advisory #GHSA-gxq4-mv8h-6qj4.

Log poisoning, a technique where malicious input is injected into log files, can exploit this flaw, potentially allowing attackers to execute arbitrary commands on the server. 

Cacti users are urged to upgrade to version 1.2.28 immediately to mitigate this risk. The development team has emphasized the importance of this update, stating that failure to patch could leave systems open to severe security breaches.

Cross-Site Scripting Vulnerabilities

In addition to the RCE vulnerability, several Cross-Site Scripting (XSS) vulnerabilities have been addressed in this release. These include:

• #GHSA-49f2-hwx9-qffr: An XSS vulnerability when creating external links with the consolenewsection parameter.
• #GHSA-fgc6-g8gc-wcg5: An XSS vulnerability associated with the title parameter.
• #GHSA-wh9c-v56x-v77c: An XSS vulnerability involving the fileurl parameter.

These vulnerabilities could allow attackers to inject malicious scripts into web pages viewed by other users, potentially leading to data theft and other malicious activities.

Additional Bug Fixes and Features

The release addresses several non-security-related issues and introduces new features to improve Cacti’s functionality and user experience.

Notable fixes include resolving LDAP authentication warnings (#5636), addressing replication loops during installation (#5754), and ensuring proper data source record ordering (#5771). 

New features include enhanced logging capabilities (#5784), improved graph display settings (#5819), and updates to key libraries such as jQuery and Purify.js.

These enhancements reflect ongoing efforts by the Cacti development community to refine and expand the tool’s capabilities.

The Cacti team continues to encourage community involvement in its development process. Users can contribute by submitting issues, forking repositories, and providing pull requests on GitHub.
