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.

Backdoor.Win32.Delf.wr / Port Bounce Scan - the CrazyInvadres Group⌐ bY SMURF_NS malware runs an FTP server on TCP port 64554 and accepts any username/password credentials. Third-party attackers 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.

 65000 udp trojans not scanned Devil trojan horse 1.03

Backdoor.Win32.Whgrx / Remote Host Header Stack Buffer Overflow - the specimen listens on datagram UDP port 65000, by sending a specially crafted HTTP PUT request and specifying a large string of characters for the HOST header we trigger the buffer overflow overwriting stack registers. Upon running the malware it may display a "Cannot load shared library wsocx.dll" message but still runs normally. The exploit payload specifies both 41414141 and 42424242 pattern with 42424242 overwriting SEH and ECX register, the 42424242 pattern was target the HTTP HOST header.
