Service fingerprinting via unintentionally exposed SSH interface
Published Jun 12, 2024 · Updated Aug 1, 2024
Resource exposure in Schneider Electric EVlink Home Smart 2.0.3.8.2_128 and 2.0.4.1.2_131 allows remote attackers to fingerprint its SSH service. The product network interface leaves the SSH service enabled and reachable instead of restricting it to its intended management sphere. Authentication blocks shell access, but the exposure permits port scans, fingerprinting, and denial-of-service attempts against SSH without reported unauthorized product operation.
