Root Cause Analysis

The vulnerability is a command injection in the Chaos Controller Manager, specifically in the cleanIptables GraphQL mutation. The root cause is the improper construction of iptables commands by directly concatenating user-controlled input (chain.Name) into the command string. The provided commit information, although a mitigation, reveals the vulnerable code pattern in the setIptablesChain function within pkg/chaosdaemon/iptables_server.go. It is highly probable that the function responsible for cleaning iptables chains, which is called by the cleanIptables mutation, suffers from the same flaw. The exploitation path starts at the GraphQL resolver CleanIptables in the controller manager, which then calls the CleanIptablesChains gRPC method on the chaos-daemon. This method, in turn, calls a function that executes the vulnerable iptables command. Therefore, monitoring for calls to these functions can indicate an attempt to exploit this vulnerability.
