Security readout for executives and security teams
An older ACC/Ericsson Tigris remote access server fails to log Radius accounting data correctly when a user first mistypes their password and then logs in successfully on a later attempt. Sessions can appear to be missing from audit trails, weakening billing accuracy and forensic investigation. The flaw is a logging integrity issue, not a direct pathway for attackers to break in. Exposure is limited to organizations still running legacy ACC/Ericsson Tigris remote access servers (dial-up/ISDN era hardware) below firmware 11.5.4.22. Modern enterprises are unlikely to have this equipment in production; any residual exposure would be in unmodernized telecom, ISP, or legacy remote access environments. Low priority for most organizations. Only act if Tigris hardware is confirmed in use; then treat it as an audit-integrity and billing-accuracy issue, not an active breach risk. Prioritize behind any modern remote access or KEV-listed vulnerabilities. Mitigation focus: Inventory any surviving ACC/Ericsson Tigris remote access servers and confirm firmware version.; Upgrade affected units to firmware 11.5.4.22 or later per vendor guidance.; Retire legacy Tigris hardware where feasible and migrate to a supported access platform..
