FiberHome ONU GPON AN5506-04-F RP2617 is affected by an OS command injection vulnerability. This vulnerability allows the attacker, once logged in, to send commands to the operating system as the root user via the ping diagnostic tool, bypassing the IP address field, and concatenating OS commands with a semicolon.

Cross Site Scripting vulnerability in FiberHome HG6544C RP2743 allows an attacker to execute arbitrary code via the SSID field in the WIFI Clients List not being sanitized

FIberHome AN5506-04-FA / HG6245D Routers Remote Stack Overflow

FiberHome AN5506-04-FA firmware versions up to and including RP2631 and HG6245D prior to RP2602 contain a stack-based buffer overflow, as the HTTP service ('webs') fails to enforce maximum lengths for Cookie header values. When a cookie longer than 511 bytes is processed, a stack buffer is overrun, leading to a crash or potential control of execution flow.

A vulnerability in FiberHome GPON ONU HG6145F1 RP4423 allows the device's factory default Wi-Fi password (WPA/WPA2 pre-shared key) to be predicted from the SSID. The device generates default passwords using a deterministic algorithm that derives the router passphrase from the SSID, enabling an attacker who can observe the SSID to predict the default password without authentication or user interaction.

An issue was discovered on FiberHome User End Routers Bearing Model Number AN1020-25 which could allow an attacker to easily restore a router to its factory settings by simply browsing to the link http://[Default-Router-IP]/restoreinfo.cgi & execute it. Due to improper authentication on this page, the software accepts the request hence allowing attacker to reset the router to its default configurations which later could allow attacker to login to router by using default username/password.

An issue was discovered on FiberHome Fengine S5800 switches V210R240. An unauthorized attacker can access the device's SSH service, using a password cracking tool to establish SSH connections quickly. This will trigger an increase in the SSH login timeout (each of the login attempts will occupy a connection slot for a longer time). Once this occurs, legitimate login attempts via SSH/telnet will be refused, resulting in a denial of service; you must restart the device.

On FiberHome routers, Directory Traversal exists in /cgi-bin/webproc via the getpage parameter in conjunction with a crafted var:page value.
