CVE-2020-6954Public exploitNetwork attack vector

Password disclosure via Connection String Test URL

Published Jan 13, 2020 · Updated Aug 4, 2024

Information disclosure in CAYIN SMP-PRO4 devices allows remote authenticated users to read a saved password through the web interface. The Connection String Test places the configured credential in clear text in the webpass query parameter of a media_folder.cgi URL instead of withholding it. Access to Web Manager and a saved Content Update Wizard password are required; the exposed credential can be reused against the configured service.
