1 CVE-2008-1529 255 2008-03-26 2008-09-05
5.0
None Remote Low Not required Partial None None
ZyXEL Prestige routers have a minimum password length for the admin account that is too small, which makes it easier for remote attackers to guess passwords via brute force methods.
2 CVE-2008-1528 287 2008-03-26 2008-09-05
4.0
None Remote Low Single system Partial None None
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.
3 CVE-2008-1527 310 2008-03-26 2008-09-05
7.5
None Remote Low Not required Partial Partial Partial
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.
4 CVE-2008-1526 310 2008-03-26 2008-09-05
5.0
None Remote Low Not required Partial None None
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), do not use a salt when calculating an MD5 password hash, which makes it easier for attackers to crack passwords.
5 CVE-2008-1525 16 2008-03-26 2008-09-05
5.0
None Remote Low Not required None Partial None
The default SNMP configuration on ZyXEL Prestige routers, including P-660 and P-661 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), has a Trusted Host value of 0.0.0.0, which allows remote attackers to send SNMP requests from any source IP address.
6 CVE-2008-1524 16 XSS 2008-03-26 2008-09-05
7.5
None Remote Low Not required Partial Partial Partial
The SNMP service on ZyXEL Prestige routers, including P-660 and P-661 models with firmware 3.40(AGD.2) through 3.40(AHQ.3), has "public" as its default community for both (1) read and (2) write operations, which allows remote attackers to perform administrative actions via SNMP, as demonstrated by reading the Dynamic DNS service password or inserting an XSS sequence into the system.sysName.0 variable, which is displayed on the System Status page.
7 CVE-2008-1523 200 +Info 2008-03-26 2008-09-05
5.0
None Remote Low Not required Partial None None
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 ISP and Dynamic DNS credentials by sending a direct request for (1) WAN.html, (2) wzPPPOE.html, and (3) rpDyDNS.html, and then reading the HTML source.
8 CVE-2008-1522 16 2008-03-26 2008-09-05
7.5
None Remote Low Not required Partial Partial Partial
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.
9 CVE-2008-1521 264 +Priv 2008-03-26 2008-09-05
6.5
None Remote Low Single system Partial Partial Partial
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.
10 CVE-2007-4319 DoS CSRF 2007-08-13 2008-11-15
4.0
None Remote Low Single system None None Partial
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.
11 CVE-2007-4318 XSS 2007-08-13 2008-11-15
4.3
None Remote Medium Not required None Partial None
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.
12 CVE-2007-4317 CSRF 2007-08-13 2008-11-15
4.3
None Remote Medium Not required None Partial None
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.
13 CVE-2007-4316 2007-08-13 2008-11-15
4.3
None Remote Medium Not required None Partial None
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.
