CVE-2023-25072Network attack vector

Unauthenticated WebUI password recovery via weak default credentials

Published May 10, 2023 · Updated Jan 28, 2025

Weak credentials in Seiko Solutions SkyBridge MB-A100/A110 firmware 4.2.0 and earlier allow remote attackers to recover the WebUI password. The WebUI uses a simple initial password that remote attackers can decode, but Seiko Solutions has not disclosed the password-generation or decoding operation. Reachability to the WebUI is required; recovered credentials permit administrative WebUI access and expose configuration data to reading or modification.
