Weakness (CWE)
CWE-385: Covert Timing Channel
Covert timing channels convey information by modulating some aspect of system behavior over time, so that the program receiving the information can observe system behavior and infer protected information.
How to prevent it (3 mitigations)
-
Architecture and Design
Whenever possible, specify implementation strategies that do not introduce time variances in operations.
-
Implementation
Often one can artificially manipulate the time which operations take or -- when operations occur -- can remove information from the attacker.
-
Implementation
It is reasonable to add artificial or random delays so that the amount of CPU time consumed is independent of the action being taken by the application.

free5GC AUSF uses non-constant-time authentication comparisons and logs XRES* in 5G-AKA
free5GC is an open-source implementation of the 5G core network. Prior to 1.4.5, the AUSF component performs cryptographic authentication comparisons in internal/sbi/processor/ue_authentication.go with ordinary equality helpers. Auth5gAkaComfirmRequestProcedu…

IBM Common Cryptographic Architecture information disclosure
Under certain conditions, RSA operations performed by IBM Common Cryptographic Architecture (CCA) 7.0.0 through 7.5.36 may exhibit non-constant-time behavior. This could allow a remote attacker to obtain sensitive information using a timing-based attack. IBM …
