Summary

An OS command injection vulnerability in NASA HyperCP (main branch) allows a network-adjacent attacker who can intercept or spoof responses from oceandata.sci.gsfc.nasa.gov to execute arbitrary system commands on the researcher's workstation. The Source/OBPGSession.py handler parses server response headers without sanitization and passes attacker-controlled field values to subprocess calls, enabling arbitrary command execution when a user performs a data download operation against a tampered se…
