CVE-2018-20727 : Vulnerability Insights and Analysis

NeDi prior to version 1.7Cp3 is susceptible to multiple command injection vulnerabilities that can be exploited by authenticated users to execute arbitrary code on the server. The vulnerabilities involve manipulating specific parameters in various PHP files.

Understanding CVE-2018-20727

NeDi versions before 1.7Cp3 are affected by security weaknesses that allow for command injection attacks.

What is CVE-2018-20727?

Command injection vulnerabilities in NeDi before version 1.7Cp3 enable authenticated users to run malicious code on the server by tampering with specific parameters in Nodes-Traffic.php, Devices-Graph.php, and drawmap.php.

The Impact of CVE-2018-20727

These vulnerabilities pose a significant risk as they can be leveraged by attackers with authenticated access to execute arbitrary commands on the server, potentially leading to unauthorized actions and data breaches.

Technical Details of CVE-2018-20727

NeDi's susceptibility to command injection attacks is a critical security concern.

Vulnerability Description

The vulnerabilities in NeDi before version 1.7Cp3 allow authenticated users to execute code on the server by manipulating the flt parameter in Nodes-Traffic.php, the dv parameter in Devices-Graph.php, or the tit parameter in drawmap.php.
