Vulnerability details
An issue was discovered on goTenna Mesh devices with app 5.5.3 and firmware 1.1.12. It uses a custom implementation of encryption without any additional integrity checking mechanisms. This leaves messages malleable to an attacker that can access the message.

Why these techniques?
The custom encryption lacks integrity checks, making transmitted messages malleable to modification by an attacker with access to the communication medium (e.g., radio signals), enabling Transmitted Data Manipulation.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Irrefutable evidence of actions requires integrity protection to prevent tampering or alteration of records.
Implements required signature-based integrity verification, addressing missing support for integrity checks on components.
Requiring control over the integrity of all changes directly compels developers to implement integrity verification mechanisms rather than omitting them.
Tamper detection fundamentally depends on integrity-checking capabilities that this control mandates or strengthens.
Explicitly requires support for integrity and authenticity checks on components before acceptance into the system.
Supplies the integrity-check artifacts (e.g., RRSIG, DNSKEY) that were previously missing for DNS responses.
Control explicitly adds support for integrity mechanisms such as checksums during preparation, preventing attacks that rely on missing integrity checks.
Directly supplies the missing integrity verification mechanism the weakness describes.
