AI-Generated

A vulnerability in the aap-gateway component of Ansible Automation Platform's Event-Driven Ansible (EDA) allows unauthenticated remote attackers to bypass mutual TLS authentication for event streams by manipulating the event stream URL and forging the HTTP Subject header. This can lead to the injection of arbitrary events, potentially triggering unauthorized automated workflows. Organizations utilizing Ansible Automation Platform should prioritize patching this vulnerability to mitigate the risk of unauthorized event manipulation.

Original NVD Description

A flaw was found in aap-gateway, a component of Ansible Automation Platform's Event-Driven Ansible (EDA). An unauthenticated remote attacker can bypass mutual Transport Layer Security (mTLS) authentication for event streams. This is achieved by manipulating the event stream URL and forging the HTTP Subject header. The system also inadvertently discloses the expected certificate subject in error messages, which simplifies the attack. This vulnerability allows an attacker to inject arbitrary events into EDA, potentially triggering automated workflows.
