Title
NASA CryptoLib 1.5.0 - TC receive path accepts Security Associations from the wrong GVCID
Summary
NASA CryptoLib 1.5.0 contains an authentication downgrade vulnerability in the Telecommand (TC) receive path. The receiver selects the Security Association used for SDLS processing solely from the SPI field inside the incoming frame, but it does not verify that the selected SA is authorized for the frame's GVCID.
