VLAI?
Summary
Character injection in Hubble CLI
Details

Impact

A network attacker could inject malicious control characters into Hubble CLI terminal output, potentially leading to loss of integrity and manipulation of the output. This could be leveraged to conceal log entries, rewrite output, or even make the terminal temporarily unusable. Exploitation of this attack would require the victim to be monitoring Kafka traffic using Layer 7 Protocol Visibility at the time of the attack.

Patches

This issue affects all versions of Hubble CLI before v1.17.2. The issue is patched in Hubble CLI v1.17.2, via https://github.com/cilium/cilium/pull/37401.

Workarounds

Hubble CLI users who are unable to upgrade can direct their Hubble flows to a log file and inspect the output within a text editor.

Acknowledgements

The Cilium community has worked together with members of Isovalent and the Cisco ASIG team to prepare these mitigations. Special thanks to @bipierce-cisco and @kokelley-cisco for reporting the issue and to @devodev for the fix.
