The web interface for Pingtel xpressa SIP-based voice-over-IP phone 1.2.5 through 1.2.7.4 allows administrators to cause a denial of service by modifying the SIP_AUTHENTICATE_SCHEME value to force authentication of incoming calls, which does not notify the user when an authentication failure occurs.

Security readout for executives and security teams

This CVE affects old Pingtel xpressa SIP VoIP phones. An administrator using the phone web interface could change a SIP authentication setting in a way that prevents incoming calls from alerting the user after authentication failures. The business impact is availability loss for affected desk phones, not data theft. Exposure appears limited to environments still running Pingtel xpressa phones on versions 1.2.5 through 1.2.7.4, especially where the administrative web interface is reachable by untrusted or loosely controlled users. Treat this as a targeted legacy availability issue. It is not currently evidenced as internet-scale or actively exploited, but affected phones could silently miss calls if misconfigured. Prioritize inventory and access restriction over emergency response. Mitigation focus: Inventory Pingtel xpressa phones and firmware versions in voice networks.; Restrict the phone web interface to trusted administrative networks only.; Review vendor advisory guidance before changing SIP authentication settings..
