CVE-2024-39220Public exploitNetwork attack vector

SIP credential disclosure via settings API

Published Jul 3, 2024 · Updated Aug 2, 2024

Credential disclosure in BAS-IP intercom firmware before 3.9.2 allows remote authenticated users to read SIP account passwords. The /api/v1/device/sip/settings endpoint returns the SIP password in cleartext when an administrator sends a GET request. Web-interface administrator credentials and network access are required, and exposure is limited to the configured SIP credential.
