A critical vulnerability in Google's Dialogflow CX could enable attackers with edit rights to compromise multiple chatbots in the same project, potentially allowing them to read user conversations and send unauthorized messages. Google has issued a fix for this flaw, identified as Rogue Agent, though there is no evidence of its exploitation in the wild.
Security firm Varonis discovered a critical vulnerability in Google Dialogflow CX, named Rogue Agent. This flaw could permit an attacker with certain permissions to access and manipulate multiple Code Block-enabled agents within the same Google Cloud project.
The vulnerability arises from the shared environment where Dialogflow Code Blocks execute custom Python, which is run in a Google-managed Cloud Run environment. Due to inadequate isolation, a writable file named code_execution_env.py allowed a malicious actor to overwrite it, leading to potential exploits in all associated chatbots.
Successful exploitation of the vulnerability required the attacker to have dialogflow.playbooks.update permissions on at least one agent. This significantly restricts the threat landscape to insiders or compromised developer accounts rather than external attackers.
Google has addressed the flaw, affirming that there were no indications of its exploitation in real world scenarios. This incident underlines significant security implications for organizations using Dialogflow CX, particularly concerning their access management and Code Block implementation strategies.
