CVE-2014-2560Public exploitNetwork attack vector

Credential-hash disclosure via invalid SIP challenge

Published Feb 12, 2020 · Updated Aug 6, 2024

Information disclosure in PhonerLite before 2.15 allows remote attackers to obtain SIP credential hashes through a spoofed call. When a user answers and ends an attacker-initiated TCP call, PhonerLite accepts a 401 challenge from the peer and sends a second BYE with an MD5 digest response in its Authorization header. An unauthenticated attacker must reach TCP port 5060 and induce user interaction; the disclosed hash enables offline password cracking, and a successful crack grants SIP account access.
