CVE-2020-37123 Scanner

Pinger is a software tool used by network administrators and IT professionals to perform network operations such as ping tests and socket communications. Its purpose is to test the reachability of hosts on an IP network and to measure round-trip time. Pinger is typically used in network troubleshooting and performance analysis contexts. It helps in verifying the status of network resources and in diagnosing network connectivity issues. The software finds its application across enterprises where network reliability and diagnostics are of high priority. It is particularly useful in environments with complex network setups requiring constant monitoring.

This Remote Code Execution (RCE) vulnerability allows an attacker to execute arbitrary system commands. The vulnerability stems from insufficient input validation on the 'ping' and 'socket' parameters in Pinger. Remote code execution vulnerabilities are critical as they potentially allow attackers to take complete control of the affected system. When exploited, it could lead to unauthorized access and manipulation of system resources. Effective mitigation strategies typically include rigorous input validation and secure coding practices. This scanner gives insight into potentially vulnerable systems by identifying components susceptible to this exploit.

The vulnerability exists within the 'ping.php' endpoint of Pinger. This endpoint fails to sanitize user input, allowing attackers to inject malicious shell commands. The 'ping' parameter is particularly vulnerable, as it uses unsanitized input. Attackers can append shell metacharacters to this parameter to execute arbitrary PHP files. This poses a significant threat as it allows the execution of system commands on the server. The vulnerability can be readily exploited through crafted HTTP requests aimed at the 'ping.php' script.

Exploitation of this vulnerability may lead to unauthorized execution of system commands, potentially compromising server integrity. Attackers could gain access to sensitive data or disrupt network operations. The vulnerability's critical nature might allow an attacker to further escalate privileges on the compromised system. This could extend the threat to include code execution on connected systems within the network. Consequently, exposure to this RCE vulnerability poses a substantial risk to network integrity and data security. Organizations using Pinger 1.0 are advised to take immediate remediation actions.
