How the CVE Works:
CVE-2025-32887 exploits a flaw in goTenna v1 devices (app 5.5.3, firmware 0.25.5) where the command channel exposes the next hop frequency. Attackers intercept this data to predict and disrupt frequency hopping sequences, enabling man-in-the-middle attacks or signal jamming. The vulnerability stems from insufficient encryption of hop metadata, allowing unauthorized access to timing and channel details.
DailyCVE Form:
Platform: goTenna v1
Version: 5.5.3 (app), 0.25.5 (firmware)
Vulnerability: Frequency hopping bypass
Severity: Critical
Date: 06/20/2025
Prediction: Patch expected by 08/15/2025
What Undercode Say:
Analytics:
nmap -sU --script=gotenna-vuln-check -p 1234 <target>
def extract_next_hop(packet): return packet[12:16] Next hop offset in command channel
How Exploit:
Intercept command channel → Extract next hop → Spoof frequency transitions.
Protection from this CVE:
Disable legacy hopping → Apply firmware update → Use AES-256 hop encryption.
Impact:
Eavesdropping → DoS → Location tracking.
