  • •NASA's AIT-GUI software has a critical vulnerability allowing unauthenticated access.
  • •The flaw affects versions up to 2.5.1 and has a CVSS score of 9.4.
  • •Attackers can exploit the vulnerability remotely via a malicious webpage.

A critical vulnerability in NASA's AMMOS Instrument Toolkit (AIT-GUI) software, tracked as GHSA-p9r8-2q67-fp86, allows unauthenticated attackers to issue commands to spacecraft and execute scripts. The flaw affects AIT-GUI versions up to 2.5.1 and has a CVSS rating of 9.4. Discovered by Cycode researcher Yuval Elbar on August 18, 2026, the vulnerability allows attackers to exploit access-control failures through an open web server interface. Attackers can gain access without being on the same network, potentially uploading malware via a malicious webpage. AIT-GUI 2.5.2 has been released to address this issue. The vulnerability also enables remote code execution through a chained exploit involving the /tlm/query endpoint. Administrators are advised to upgrade to the latest version and review security practices.
