| ZyXEL Prestige routers, including P-660 and P-661 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), have (1) "user" as their default password for the "user" account and (2) "1234" as their default password for the "admin" account, which makes it easier for remote attackers to obtain access. | |||||
| CVE-2008-1528 | 1 Zyxel | 3 Prestige 660, Prestige 661, Zynos | 2025-04-09 | 4.0 MEDIUM | N/A |
| ZyXEL Prestige routers, including P-660, P-661, and P-662 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), allow remote authenticated users to obtain authentication data by making direct HTTP requests and then reading the HTML source, as demonstrated by a request for (1) RemMagSNMP.html, which discloses SNMP communities; or (2) WLAN.html, which discloses WEP keys. | |||||
| CVE-2008-1260 | 1 Zyxel | 1 P-2602hw-d1a | 2025-04-09 | 4.3 MEDIUM | N/A |
| Multiple cross-site request forgery (CSRF) vulnerabilities on the Zyxel P-2602HW-D1A router with 3.40(AJZ.1) firmware allow remote attackers to (1) make the admin web server available on the Internet (WAN) interface via the WWWAccessInterface parameter to Forms/RemMagWWW_1 or (2) change the IP whitelisting timeout via the StdioTimout parameter to Forms/rpSysAdmin_1. | |||||
| CVE-2020-29583 | 1 Zyxel | 60 Atp100, Atp100 Firmware, Atp100w and 57 more | 2025-04-03 | 10.0 HIGH | 9.8 CRITICAL |
