An issue was discovered on ARRIS TG852G, TG862G, and TG1672G devices. A remote attacker (in proximity to a Wi-Fi network) can derive the default WPA2-PSK value by observing a beacon frame.
Cross-site scripting (XSS) vulnerability in advpwdcgi in the web management interface on Arris DG860A, TG862A, and TG862G devices with firmware TS0703128100611 through TS0705125D031115 allows remote attackers to inject arbitrary web script or HTML via the pwd parameter.
Cross-site request forgery (CSRF) vulnerability in advpwdcgi in the web management interface on Arris DG860A, TG862A, and TG862G devices with firmware TS0703128100611 through TS0705125D031115 allows remote attackers to hijack the authentication of arbitrary users.
Arris DG860A, TG862A, and TG862G devices with firmware TS0703128100611 through TS0705125D031115 have a hardcoded administrator password derived from a serial number, which makes it easier for remote attackers to obtain access via the web management interface, SSH, TELNET, or SNMP.
Arris DG860A, TG862A, and TG862G devices with firmware TS0703128100611 through TS0705125D031115 have predictable technician passwords, which makes it easier for remote attackers to obtain access via the web management interface, related to a "password of the day" issue.
Cross-site scripting (XSS) vulnerability in ARRIS Touchstone TG862G/CT Telephony Gateway with firmware 7.6.59S.CT and earlier allows remote authenticated users to inject arbitrary web script or HTML via the computername parameter to connecteddevicescomputersedit.php.
Multiple cross-site request forgery (CSRF) vulnerabilities in ARRIS Touchstone TG862G/CT Telephony Gateway with firmware 7.6.59S.CT and earlier allow remote attackers to hijack the authentication of administrators for requests that (1) enable remote management via a request to remotemanagement.php, (2) add a port forwarding rule via a request to portforwardingadd.php, (3) change the wireless network to open via a request to wirelessnetworkconfigurationedit.php, or (4) conduct cross-site scripting (XSS) attacks via the keyword parameter to managedsitesaddkeyword.php.
