Technical description

CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.2, there is a command Injection vulnerability in initialize_kerberos_keytab_file_login(). The vulnerability exists because the code directly interpolates user-controlled input into a shell command and executes it via system() without any sanitization or validation. This issue has been patched in version 1.4.2.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
