An issue was discovered on Dasan GPON home routers. Command Injection can occur via the desthost parameter in a diagaction=ping request to a GponForm/diagForm URI. Because the router saves ping results in /tmp and transmits them to the user when the user revisits /diag.html, it's quite simple to execute commands and retrieve their output.
An issue was discovered on Dasan GPON home routers. It is possible to bypass authentication simply by appending "?images" to any URL of the device that requires authentication, as demonstrated by the /menu.html?images/ or /GponForm/diagFORM?images/ URI. One can then manage the device.
An authentication bypass issue was discovered in Dasan Switch DS2924 web based interface, firmware versions 1.01.18 and 1.02.00, allowing attackers to gain escalated privileges via storing crafted cookies in the web browser.
The Boa server configuration on DASAN H660RM devices with firmware 1.03-0022 logs POST data to the /tmp/boa-temp file, which allows logged-in users to read the credentials of administration web interface users.
DASAN H660RM devices with firmware 1.03-0022 use a hard-coded key for logs encryption. Data stored using this key can be decrypted by anyone able to access this key.
diagtool.cgi on DASAN H660RM GPON routers with firmware 1.03-0022 lacks any authorization check, which allows remote attackers to run a ping command via a GET request to enumerate LAN devices or crash the router with a DoS attack.
The backdoor account dnsekakf2$$ in /bin/login on DASAN H665 devices with firmware 1.46p1-0028 allows an attacker to login to the admin account via TELNET.
Buffer overflow on Dasan GPON ONT WiFi Router H640X 12.02-01121 2.77p1-1124 and 3.03p2-1146 devices allows remote attackers to execute arbitrary code via a long POST request to the loginaction function in /cgi-bin/loginaction.cgi (aka cgipage.cgi).
The Port Forwarding functionality on DASAN H660GW devices allows remote attackers to execute arbitrary code via shell metacharacters in the cgi-bin/advnatvirsvr.asp Addr parameter (aka the Local IP Address field).
