CVE-2009-5139
The SIP implementation on the Gizmo5 software phone provides hashed credentials in a response to an invalid authentication challenge, which makes it easier for remote attackers to obtain access via a brute-force attack, related to a "SIP Digest Leak"…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
