CVE-2006-2166: Unspecified vulnerability in the HTTP management interface in Cisco Unity Express (CUE) 2.2(2) and earlier,...

Security readout for executives and security teams

This vulnerability affects older Cisco Unity Express management interfaces. An authenticated remote user could reset the password for any account whose password had expired. In business terms, a low-privilege account with management access could potentially take over expired user accounts, including higher-value accounts, if the affected legacy CUE version is still running. Exposure is most likely in legacy environments still operating Cisco Unity Express 2.2(2) or earlier with the HTTP management interface reachable to authenticated users. Internet exposure is not stated in the sources and should not be assumed. Treat this as a legacy infrastructure risk. It is not listed as known exploited in the provided sources, but affected systems can enable account takeover through management access. Prioritize if CUE remains operational or manages sensitive voicemail or telephony administration. Mitigation focus: Check Cisco advisory guidance for supported fixed versions or configuration mitigations.; Inventory Cisco Unity Express instances and confirm CUE software versions.; Restrict HTTP management access to trusted administrative networks only..
