The attack described involvesinjecting arbitrary syntaxthat isexecuted by the underlying operating system, characteristic of aCommand Injectionattack.
Nature of Command Injection:
Direct OS Interaction:Attackers input commands that are executed by the server’s OS.
Vulnerability Vector:Often occurs when user input is passed to system calls without proper validation or sanitization.
Examples:Using characters like ;, &&, or | to append commands.
Common Scenario:Exploiting poorly validated web application inputs that interact with system commands (e.g., ping, dir).
Other options analysis:
B. Injection:Targets databases, not the underlying OS.
C. LDAP Injection:Targets LDAP directories, not the OS.
D. Insecure direct object reference:Involves unauthorized access to objects through predictable URLs, not OS command execution.
