Broadcom based cable modems across multiple vendors are vulnerable to a buffer overflow, which allows a remote attacker to execute arbitrary code at the kernel level via JavaScript run in a victim's browser. Examples of affected products include Sagemcom F@st 3890 prior to 50.10.21_T4, Sagemcom F@st 3890 prior to 05.76.6.3f, Sagemcom F@st 3686 3.428.0, Sagemcom F@st 3686 4.83.0, NETGEAR CG3700EMR 2.01.05, NETGEAR CG3700EMR 2.01.03, NETGEAR C6250EMR 2.01.05, NETGEAR C6250EMR 2.01.03, Technicolor TC7230 STEB 01.25, COMPAL 7284E 5.510.5.11, and COMPAL 7486E 5.510.5.11.
The web interface on the Technicolor TC7230 STEB 01.25 is vulnerable to DNS rebinding, which allows a remote attacker to configure the cable modem via JavaScript in a victim's browser. The attacker can then configure the cable modem to port forward the modem's internal TELNET server, allowing external access to a root shell.
An XSS vulnerability on Technicolor TC7300 STFA.51.20 devices allows remote attackers to inject arbitrary web script via the FileName parameter to /FTPDiag.asp.
An XSS vulnerability on Technicolor TC7300 STFA.51.20 devices allows remote attackers to inject arbitrary web script via the "Connected Clients" field to /wlanAccess.asp. An intranet host can use a crafted hostname to exploit this.
An issue was discovered in certain Oi third-party firmware that may be installed on Technicolor TD5130v2 devices. A Command Injection in the Ping module in the Web Interface in OI_Fw_V20 allows remote attackers to execute arbitrary OS commands in the pingAddr parameter to mnt_ping.cgi. NOTE: This may overlap CVE-2017–14127.
The admin web interface on Technicolor MediaAccess TG789vac v2 HP devices with firmware v16.3.7190-2761005-20161004084353 displays unsanitised user input, which allows an unauthenticated malicious user to embed JavaScript into the Log viewer interface via a crafted HTTP Referer header, aka XSS.
