Uncovering the Airbus Navblue Flysmart+ Manager Vulnerability: A Call to Ensure Aviation App Security

In today’s rapidly evolving digital landscape, ensuring the security of aviation apps becomes paramount to guaranteeing flight safety. A recent discovery by Pen Test Partners has shed light on a significant vulnerability within the Airbus Navblue Flysmart+ Manager, a sophisticated suite designed to aid in the efficient and safe departure and arrival of flights. This discovery highlights the critical need for stringent security measures in the development and maintenance of such applications.

Understanding the Vulnerability in Flysmart+ Manager

At the heart of this issue lies a vulnerability that could potentially allow attackers to manipulate engine performance calculations and intercept sensitive data. This poses a tangible risk of tailstrike or runway excursion incidents during departure, underscoring the gravity of the situation. Researchers identified that the flaw stemmed from one of the iOS apps having its App Transport Security (ATS) deliberately disabled.

ATS is a critical security feature that enforces the usage of HTTPS protocol, thus ensuring encrypted communication. The bypass of ATS in this scenario paves the way for insecure communications, allowing attackers to potentially force the use of unencrypted HTTP protocol and intercept data being transmitted to and from the server.

Potential Consequences and Attack Scenarios

The implications of this vulnerability are not to be understated. By exploiting this flaw, attackers could modify aircraft performance data or adjust airport specifics such as runway lengths in the SQLite databases downloaded by the Flysmart+ Manager. This manipulation could have dire consequences on flight safety, including inaccurate takeoff performance calculations.

A practical attack scenario involves tampering with the app’s traffic during monthly updates over insecure networks. For example, exploiting the Wi-Fi network at a hotel frequently used by airline pilots on layovers could be a viable attack vector. By identifying pilots and the specific suite of EFB apps they utilize, an attacker could strategically target and manipulate critical flight data.

Response and Mitigation

Upon discovering this vulnerability, Pen Test Partners promptly reported the issue to Airbus in June 2022. In response, Airbus confirmed that a forthcoming software update would rectify the vulnerability. Additionally, in May 2023, Airbus proactively communicated mitigation measures to its clientele, reinforcing its commitment to flight safety and data security.


The discovery of this vulnerability within the Airbus Navblue Flysmart+ Manager serves as a poignant reminder of the constant vigilance required in safeguarding digital assets in the aviation sector. It underscores the importance of incorporating robust security protocols from the outset and the need for ongoing scrutiny to identify and address potential vulnerabilities. The proactive response by Airbus exemplifies the necessary steps to mitigate risks and protect the integrity of flight operations.

Ensuring the security of aviation technology is a collective responsibility that requires the concerted efforts of developers, security researchers, and the wider aviation community. It’s a commitment to safety that we must all uphold fervently.
