CVE-2024-52330
Published: 23 January 2025
Summary
CVE-2024-52330 is a high-severity Improper Certificate Validation (CWE-295) vulnerability in Ecovacs Deebot X2 Omni Firmware. Its CVSS base score is 7.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Network Sniffing (T1040); ranked in the top 28.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SC-17 (Public Key Infrastructure Certificates) and SC-8 (Transmission Confidentiality and Integrity).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly requires establishment of requirements for PKI certificates and validation to prevent acceptance of invalid TLS certificates in device communications.
Mandates cryptographic protection for transmission confidentiality and integrity, which proper TLS certificate validation enforces against interception and modification.
Provides integrity verification mechanisms for firmware to detect and block installation of tampered updates resulting from TLS traffic modification.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Improper TLS certificate validation enables unauthenticated MiTM attacks to sniff/decrypt traffic (T1040), intercept and modify communications (T1557), and alter firmware updates (T1495).

NVD Description
ECOVACS lawnmowers and vacuums do not properly validate TLS certificates. An unauthenticated attacker can read or modify TLS traffic, possibly modifying firmware updates.
Deeper analysisAI
CVE-2024-52330 is a vulnerability in ECOVACS lawnmowers and vacuums stemming from improper validation of TLS certificates, mapped to CWE-295. The affected devices fail to properly verify TLS certificates during communication, exposing encrypted traffic to interception and tampering. This issue carries a CVSS v3.1 base score of 7.4 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N), indicating high confidentiality and integrity impacts with network accessibility but requiring high attack complexity.
An unauthenticated attacker positioned to intercept network traffic can exploit this vulnerability via a man-in-the-middle attack to read or modify TLS-encrypted communications. Successful exploitation could allow the attacker to alter firmware updates transmitted to the devices, potentially leading to persistent compromise or malicious modifications.
ECOVACS has issued security advisory DSA-20241217001, available at https://www.ecovacs.com/global/userhelp/dsa20241217001, which likely details mitigation steps. Further technical details on the vulnerability are provided in research presentations, including those from 37C3 2023 (https://dontvacuum.me/talks/37c3-2023/37c3-vacuuming-and-mowing.pdf) and HITCON 2024 (https://dontvacuum.me/talks/HITCON2024/HITCON-CMT-2024_Ecovacs.pdf).
