Rule Vulnerability

Command Injection

Command Injection attacks target applications that allow unsafe user-supplied input. Attackers transmit this input via forms, cookies, HTTP headers, etc. and exploit the applications permissions to execute system commands without injecting code.

CVE Additional Information

This product uses data from the NVD API but is not endorsed or certified by the NVD.
CVE-2024-50603
An issue was discovered in Aviatrix Controller before 7.1.4191 and 7.2.x before 7.2.4996. Due to the improper neutralization of special elements used in an OS command, an unauthenticated attacker is able to execute arbitrary code. Shell metacharacters can be sent to /v1/api in cloud_type for list_flightpath_destination_instances, or src_cloud_type for flightpath_connection_test.

TacticInitial Access
TechniqueExploit Public-Facing Application
DescriptionAdversaries may attempt to take advantage of a weakness in an Internet-facing computer or program using software, data, or commands in order to cause unintended or unanticipated behavior. The weakness in the system can be a bug, a glitch, or a design vulnerability. These applications are often websites, but can include databases (like SQL), standard services (like SMB or SSH), network device administration and management protocols (like SNMP and Smart Install), and any other applications with Internet accessible open sockets, such as web servers and related services.
