CVE-2008-1528: ZyXEL Prestige routers, including P-660, P-661, and P-662 models with firmware 3.40(AGD.2) through 3.40(AHQ...

Security readout for executives and security teams

This issue affects older ZyXEL Prestige routers. An authenticated user of the router’s web interface could see hidden authentication data in HTML source, including SNMP community strings or WEP wireless keys. That can expose network management access or wireless credentials. Exposure is most likely in legacy networks still running the named ZyXEL Prestige models and firmware. Risk increases if router administration is reachable by untrusted internal users, remote users, or shared support accounts. Treat as a legacy-network hygiene issue with real credential exposure impact. Prioritize replacement or isolation if these routers remain in production, especially in sites with shared administration access or outdated wireless security. Mitigation focus: Inventory ZyXEL Prestige P-660, P-661, and P-662 devices and firmware versions.; Check ZyXEL guidance for fixed firmware or replacement recommendations.; Restrict router administration to trusted management networks only..
