During the device setup phase, the MSH30Q creates an unprotected Wi-Fi access point. In this phase, MSH30Q needs to connect to the Internet through a Wi-Fi router. This is why MSH30Q asks for the Wi-Fi network name (SSID) and the Wi-Fi network password. When the user enters the password, the transmission of the Wi-Fi password and name between the MSH30Q and mobile application is observed in the Wi-Fi network. Although the Wi-Fi password is encrypted, a part of the decryption algorithm is public so we complemented the missing parts to decrypt it.","severity":{"version":"3.1","score":5.7,"vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","level":"medium","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-10","score":0.00168,"percentile":0.06182,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-319"],"published":"2024-01-23T00:00:00Z","modified":"2026-06-17T06:31:48Z","products":[{"vendor":"meross","product":"msh30q_firmware"}],"references":[{"url":"https://www.kth.se/cs/nse/research/software-systems-architecture-and-security/projects/ethical-hacking-1.1279219","tags":["x_transferred","Third Party Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-46889"},{"url":"https://github.com/advisories/GHSA-hr3c-fw3g-qvhf"}],"sources":{"cve":[{"id":"CVE-2023-46889","description":"Meross MSH30Q 4.5.23 is vulnerable to Cleartext Transmission of Sensitive Information.
