A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 9 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Users should avoid using the affected firmware version until a vendor advisory or update is released. Network-level protections such as isolating the device from untrusted networks or using secure tunnels may reduce exposure. Monitor vendor communications for official remediation.

Description

The FrodoBots EarthRover Mini+ firmware version 6.2.4_6.2.5_0.614.0 uses an insecure STM32 firmware update mechanism. Firmware updates are fetched over unencrypted HTTP, and integrity is only checked using MD5 hashes transmitted in the same unprotected response. There is no code-signing mechanism, allowing attackers to potentially replace the firmware with malicious code.

Impact

An attacker capable of intercepting or manipulating network traffic can replace the STM32 motor-controller firmware with malicious code. This could lead to unauthorized control or disruption of the device's motor functions. The lack of encryption and robust integrity checks significantly increases the risk of firmware tampering.

Summary

CVE-2026-121688 describes a vulnerability in the FrodoBots EarthRover Mini+ firmware (version 6.2.4_6.2.5_0.614.0) where the STM32 motor-controller firmware update process is insecure. Firmware is downloaded over unencrypted HTTP, exposing it to interception and tampering. Integrity validation relies solely on MD5 hashes provided alongside the firmware in the same unprotected channel, which is insufficient to prevent manipulation. The absence of code-signing means malicious firmware could be injected, compromising device integrity.
