Oct 31, 2019 · Here, we launched a CVE scan against port 8443, but you can query other ports, or the entire site as well. Summary. Nmap’s powerful scripts allow you to not only perform port scanning tasks, but also to discover CVEs in a matter of seconds. Thanks to Nmap, this becomes an easy task, even if you don’t have advanced technical skills. FTP Sharing and Vulnerabilities. Although FTP is widely used, there are a number of vulnerabilities that should be addressed to ensure security. FTP authentication is sent as cleartext, making it easy for someone with a packet sniffer to view usernames and passwords. Oct 04, 2015 · From the reading I did it appears that tcp on port 53 is a security risk because hackers can perform zone transfers and map out information which they should probably not be allowed (still a little unclear exactly how that works) - which is why tcp is usually blocked by most people, however, it is now starting to be used for things like dnssec Fixed source port for generating queries; Some current implementations allocate an arbitrary port at startup (sometimes selected at random) and reuse this source port for all outgoing queries. In some implementations, the source port for outgoing queries is fixed at the traditional assigned DNS server port number, 53/udp. Online UDP port scan available for common UDP services. The UDP port scan is part of the IP Tools range of network testing tools. The test uses the excellent Nmap Port Scanner to scan 5 of the most common UDP ports. Ports tested in the quick UDP scan are DNS 53, TFTP 69, NTP 123, SNMP 161, mDNS 5353, UPNP 1900 and Memcached 11211. The WannaCry TCP port 445 exploit returned the spotlight to the vulnerabilities in Microsoft's long-abused networking port. Network security expert Kevin Beaver explained how to detect and defend The Mutillidae web application (NOWASP (Mutillidae)) contains all of the vulnerabilities from the OWASP Top Ten plus a number of other vulnerabilities such as HTML-5 web storage, forms caching, and click-jacking. Inspired by DVWA, Mutillidae allows the user to change the "Security Level" from 0 (completely insecure) to 5 (secure).
By sending specially-crafted DNS packets to TCP port 53, a remote attacker could exploit this vulnerability to cause the device to reload. References: [CVE-2013-5479], haneWIN DNS Server is vulnerable to a denial of service attack. A remote attacker could send a large amount of data to port 53 and cause the server to crash.

Apr 23, 2014 · The default port used by Microsoft SQL Server is one of the most probed ports on the Internet, along with NetBIOS port and the HTTP default port. 4. Causing downtime of line of business applications by running denial of service attacks on open ports belonging to less robust services. Each open port may be the target of denial of service (DoS Port 53 Wars: Security of the Domain Name System and Thinking About DNSSEC but in other cases local vulnerabilities may be remotely exploitable to attack other
