CVE-2022-48625Network attack vector

Deployment information disclosure via built-in RSA keys

Published Feb 19, 2024 · Updated Aug 29, 2024

Hard-coded keys in Yealink Config Encrypt Tool add RSA 1.1 and earlier allow remote attackers to decrypt AutoP deployment files. The tool ships the same default private.key and pub.key and uses the built-in public key to encrypt deployment data. Exposure requires files distributed over HTTP, FTP, or TFTP to have been encrypted with the default key pair, and the impact is limited to disclosure of deployment information.
