DEEBOT X5 PRO PLUS: Improper Certificate Validation
CVE-2024-52330 is a high-severity improper certificate validation vulnerability in DEEBOT X5 PRO PLUS from Ecovacs, with a CVSS 3.1 base score of 7.4 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.38.0 as the first without the flaw, so updating DEEBOT X5 PRO PLUS to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.35% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update DEEBOT X5 PRO PLUS to 1.38.0 or a later version.
- Update DEEBOT X5 PRO to 1.70.0 or a later version.
- Update DEEBOT X2S to 1.49.0 or a later version.
- Read the advisory on ecovacs.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
