    Title
    FIberHome AN5506-04-FA / HG6245D Routers Remote Stack Overflow
    Summary
    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.

    Vulnerability from variot - Updated: 2025-04-20 23:34

    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. FiberHome Fengine S5800 Switch has service disruption ( Reboot device ) There are vulnerabilities that are put into a state.An unauthenticated attacker SSH Service access is disrupted by accessing the service ( Reboot device ) There is a possibility of being put into a state. FiberHomeFengineS5800Switches is a new generation of Gigabit routing switches designed to meet multi-service access and high-density aggregation. The series of router switches are equipped with high-density Gigabit ports and 10 Gigabit uplinks, which can meet various applications such as broadband metropolitan area network, enterprise network, WLAN aggregation, and campus networking. A remote denial of service vulnerability exists in FiberHomeFengineS5800Switches

An unauthorized attacker can access the device\u0027s 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. FiberHome Fengine S5800 Switch has service disruption ( Reboot device ) There are vulnerabilities that are put into a state.An unauthenticated attacker SSH Service access is disrupted by accessing the service ( Reboot device ) There is a possibility of being put into a state. FiberHomeFengineS5800Switches is a new generation of Gigabit routing switches designed to meet multi-service access and high-density aggregation. The series of router switches are equipped with high-density Gigabit ports and 10 Gigabit uplinks, which can meet various applications such as broadband metropolitan area network, enterprise network, WLAN aggregation, and campus networking.

    Vulnerability from variot - Updated: 2025-04-20 23:15

    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. FiberHomeUserEndRoutersBearingAN1020-25 is a router from China FiberHome. A security vulnerability exists in FiberHomeUserEndRoutersBearingAN1020-25 that caused the program to fail to perform authentication correctly. An attacker could use this vulnerability to restore the router to factory settings and log in to the router

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. FiberHomeUserEndRoutersBearingAN1020-25 is a router from China FiberHome.

    Vulnerability from variot - Updated: 2024-11-23 22:44

    An issue was discovered on FiberHome HG6245D devices through RP2613. Credentials in /fhconf/umconfig.txt are obfuscated via XOR with the hardcoded j7a(L#yZ98sSd5HfSgGjMj8;Ss;d)(&^#@$a2s0i3g key. (The webs binary has details on how XOR is used.). FiberHome HG6245D A device contains a vulnerability in the use of hard-coded credentials.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state

    Vulnerability from variot - Updated: 2024-11-23 22:44

    An issue was discovered on FiberHome HG6245D devices through RP2613. It is possible to start a Linux telnetd as root on port 26/tcp by using the CLI interface commands of ddd and shell (or tshell). FiberHome HG6245D The device contains an out-of-bounds write vulnerability.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. FiberHome HG6245D devices is a router of China FiberHome. Provide network connectivity function.

    A buffer overflow vulnerability exists in FiberHome HG6245D devices, which can be exploited by attackers to cause buffer overflow or heap overflow
