Vulnerable Ports
This list (a very small part of our SG Ports database) includes TCP/UDP ports currently tested by our Security Scanner, and corresponding potential security threats.
We update the list on a regular basis, however if you feel we should add other port(s) to the list or modify their descriptions, please .
Any feedback and suggestions can also be posted to our Security forum.

HP Intelligent Management Center (IMC) is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the dbman.exe component. By sending a specially-crafted packet to UDP port 2810, a remote attacker could overflow a buffer and execute arbitrary code on the system with SYSTEM privileges or cause the application to crash.

Attackers may then be able to launch attacks, download files or port scan third party systems and it will appear as the attacks originated from that infected host.

Trojans using this port: Konik
An issue was discovered in KaiOS 3.0 before 3.1. The /system/bin/tctweb_server binary exposes a local web server that responds to GET and POST requests on port 2929. The server accepts arbitrary Bash commands and executes them as root. Because it is not permission or context restricted and returns proper CORS headers, it's accessible to all websites via the browser. At a bare minimum, this allows an attacker to retrieve a list of the user's installed apps, notifications, and downloads. It also allows an attacker to delete local files and modify system properties including the boolean persist.moz.killswitch property (which would render the device inoperable). This vulnerability is partially mitigated by SELinux which prevents reads, writes, or modifications to files or permissions within protected partitions.
