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.

Multiple stack-based buffer overflows in Trend Micro ServerProtect 5.58 before Security Patch 2 Build 1174 allow remote attackers to execute arbitrary code via crafted data to (1) TCP port 5168, which triggers an overflow in the CAgRpcClient::CreateBinding function in the AgRpcCln.dll library in SpntSvc.exe; or (2) TCP port 3628, which triggers an overflow in EarthAgent.exe.

WinJank [Symantec-2003-071117-5539-99] (2003.07.11) - a backdoor trojan horse that allows unauthorized access to your computer, listens to port 5277 TCP by default.
WinShell trojan also uses this port.
Backdoor.Win32.WinShell.30 / Remote Stack Buffer Overflow / Missing Authentication - WinShell.30 listens on TCP port 5277 for commands. Attackers or responders who can reach the infected host can trigger a buffer overflow by sending a large string of junk characters in place of an expected command. This will overwrite EIP and potentially allow control of the malwares execution flow. Moreover, WinShell.30 also lacks any type of authentication for inbound connections, which can allow anyone to take over the infected system.
References: [MVID-2021-0040]
Backdoor.Win32.Wisell / Unauthenticated Remote Command Execution - the malware listens on TCP port 5277, third-party attackers who can reach the system can execute OS commands further compromising the already infected system. Sending the exclaimation point character "!" will not only quit the shell, but also effectively terminate the backdoor.
References: [MVID-2021-0234]
Backdoor.Win32.Winshell.5_0 / Weak Hardcoded Credentials - the malware is UPX packed, listens on TCP port 5277 and requires authentication for remote access. However, the password "123456789" is weak and hardcoded within the PE file. Unpacking the executable, easily reveals the cleartext password.

Third-party adversaries who successfully logon can abuse the backdoor FTP server as a man-in-the-middle machine allowing PORT Command bounce scan attacks using Nmap. This vulnerability allows remote attackers to abuse your system and discreetly conduct network port scanning. Victims will then think these scans are originating from the infected system running the afflicted malware FTP Server and not you.

Backdoor.Win32.GateHell.21 / Authentication Bypass - the malware runs an FTP server on TCP ports 5301,5432,5300,5299,5298,5297,5296 and 5295. Third-party attackers who can reach infected systems can logon using any username/password combination. Intruders may then upload executables using ftp PASV, STOR commands, this
can result in remote code execution.

Remote attackers can perform a denial of service in WebRamp systems by sending a malicious UDP packet to port 5353, changing its IP address.
References: [CVE-1999-0438]
Avahi-core/socket.c in avahi-daemon in Avahi before 0.6.29 allows remote attackers to cause a denial of service (infinite loop) via an empty mDNS IPv4 or IPv6 UDP packet to port 5353.
References: [CVE-2011-1002], [BID-46446]
Avahi is vulnerable to a denial of service, caused by a NULL pointer dereference error within the avahi-core/socket.c. By sending a specially-crafted UDP packet to UDP port 5353, a remote attacker could exploit the vulnerability to cause the application to enter into an infinite loop.

The Multicast DNS (mDNS) responder in IBM Security Access Manager for Web 7.x before 7.0.0 FP12 and 8.x before 8.0.1 FP1 inadvertently responds to unicast queries with source addresses that are not link-local, which allows remote attackers to cause a denial of service (traffic amplification) or obtain potentially sensitive information via port-5353 UDP packets.
References: [CVE-2015-1892]
The Multicast DNS (mDNS) responder in Synology DiskStation Manager (DSM) before 3.1 inadvertently responds to unicast queries with source addresses that are not link-local, which allows remote attackers to cause a denial of service (traffic amplification) or obtain potentially sensitive information via port-5353 UDP packets to the Avahi component.
References: [CVE-2015-2809]
Cisco IOS and Cisco IOS XE are vulnerable to a denial of service, caused by an error within the multicast DNS (mDNS) gateway function when processing malicious packets. By sending specially-crafted IP version 4 (IPv4) or IP version 6 (IPv6) packets on UDP port 5353, a remote attacker could exploit this vulnerability to cause the device to reload.

The Multicast DNS (mDNS) responder used in BOSE Soundtouch 30 inadvertently responds to IPv4 unicast queries with source addresses that are not link-local, which allows remote attackers to cause a denial of service (traffic amplification) or obtain potentially sensitive information via port-5353 UDP packets.
References: [CVE-2017-6520], [XFDB-128565]
avahi-daemon in Avahi through 0.6.32 inadvertently responds to IPv6 unicast queries with source addresses that are not on-link, which allows remote attackers to cause a denial of service (traffic amplification) or obtain potentially sensitive information via port-5353 UDP packets. NOTE: this may overlap CVE-2015-2809.
