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-2008-1527 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2024-02-28 7.5 HIGH N/A
ZyXEL Prestige routers, including P-660, P-661, and P-662 models with firmware 3.40(PE9) and 3.40(AGD.2) through 3.40(AHQ.3), support authentication over HTTP via a hash string in the hiddenPassword field, which allows remote attackers to obtain access via a replay attack.
CVE-2008-1521 1 Zyxel 3 Prestige 660, Prestige 661, Zynos 2024-02-28 6.5 MEDIUM N/A
ZyXEL Prestige routers, including P-660 and P-661 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), allow remote authenticated users to gain privileges by accessing administrative URIs, as demonstrated by rpSysAdmin.html.
CVE-2008-1257 1 Zyxel 4 P-660hw, P-660hw D1, P-660hw D3 and 1 more 2024-02-28 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Forms/DiagGeneral_2 on the ZyXEL P-660HW series router allows remote attackers to inject arbitrary web script or HTML via the PingIPAddr parameter.
CVE-2007-4317 1 Zyxel 2 Zynos, Zywall 2 2024-02-28 4.3 MEDIUM N/A
Multiple cross-site request forgery (CSRF) vulnerabilities in the management interface in ZyNOS firmware 3.62(WK.6) on the Zyxel Zywall 2 device allow remote attackers to perform certain actions as administrators, as demonstrated by a request to Forms/General_1 with the (1) sysSystemName and (2) sysDomainName parameters.
CVE-2008-1255 1 Zyxel 1 P-660hw 2024-02-28 10.0 HIGH N/A
The ZyXEL P-660HW series router maintains authentication state by IP address, which allows remote attackers to bypass authentication by establishing a session from a source IP address of a previously authenticated user.
CVE-2008-1260 1 Zyxel 1 P-2602hw-d1a 2024-02-28 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-2008-1254 1 Zyxel 1 P-660hw 2024-02-28 6.8 MEDIUM N/A
Multiple cross-site request forgery (CSRF) vulnerabilities on the ZyXEL P-660HW series router allow remote attackers to (1) change DNS servers and (2) add keywords to the "bannedlist" via unspecified vectors.
CVE-2008-1259 1 Zyxel 1 P-2602hw-d1a 2024-02-28 9.3 HIGH N/A
The Zyxel P-2602HW-D1A router with 3.40(AJZ.1) firmware maintains authentication state by IP address, which allows remote attackers to bypass authentication by establishing a session from a source IP address of a user who previously authenticated within the previous 5 minutes.
CVE-2008-1256 1 Zyxel 1 P-660hw 2024-02-28 10.0 HIGH N/A
The ZyXEL P-660HW series router has "admin" as its default password, which allows remote attackers to gain administrative access.
CVE-2007-1586 1 Zyxel 1 Zynos 2024-02-28 7.8 HIGH N/A
ZynOS 3.40 allows remote attackers to cause a denial of service (link restart) by sending a request for the name \M via the SMB Mail Slot Protocol.
CVE-2007-4316 1 Zyxel 2 Zynos, Zywall 2 2024-02-28 4.3 MEDIUM N/A
The management interface in ZyNOS firmware 3.62(WK.6) on the Zyxel Zywall 2 device has a certain default password, which allows remote attackers to perform administrative actions.

The management interface in ZyNOS firmware 3.62(WK.6) on the Zyxel Zywall 2 device allows remote authenticated administrators to cause a denial of service (infinite reboot loop) via invalid configuration data. NOTE: this issue might not cross privilege boundaries, and it might be resultant from CSRF; if so, then it should not be included in CVE.
CVE-2007-4318 1 Zyxel 2 Zynos, Zywall 2 2024-02-28 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Forms/General_1 in the management interface in ZyNOS firmware 3.62(WK.6) on the Zyxel Zywall 2 device allows remote authenticated administrators to inject arbitrary web script or HTML via the sysSystemName parameter.
CVE-2008-1261 1 Zyxel 1 P-2602hw-d1a 2024-02-28 5.0 MEDIUM N/A
The Zyxel P-2602HW-D1A router with 3.40(AJZ.1) firmware provides different responses to admin page requests depending on whether a user is logged in, which allows remote attackers to obtain current login status by requesting an arbitrary admin URI.
