FiberhomeCVEs & Vulnerabilities

An issue was discovered on FiberHome HG6245D devices through RP2613. The web daemon contains the hardcoded user / tattoo@home credentials for an ISP.

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.

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.

A vulnerability, which was classified as critical, has been found in FiberHome AN5506-01A ONU GPON RP2511. Affected by this issue is some unknown functionality of the component Diagnosis. The manipulation of the argument Destination Address leads to os command injection. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

A vulnerability classified as problematic was found in FiberHome AN5506-01A ONU GPON RP2511. Affected by this vulnerability is an unknown functionality of the component NAT Submenu.
