Vendor Workaround
After consulting with the Federal Aviation Administration (FAA) and the researchers regarding these vulnerabilities, it has been concluded that CVE-2024-11166 can be fully mitigated by upgrading to ACAS X or by upgrading the associated transponder to comply with RTCA DO-181F. Currently, there is no mitigation available for CWE-2024-9310. These vulnerabilities in the TCAS II standard are exploitable in a lab environment. However, they require very specific conditions to be met and are unlikely to be exploited outside of a lab setting. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents. No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time. These vulnerabilities are not exploitable remotely. These vulnerabilities have a high attack complexity.
