Security vulnerability assessment pdf

The vulnerability is caused by an unchecked buffer in the Microsoft ASN. Severity rating of CVE Microsoft, 2. Microsoft, 2. LOG log file, as exploited by the Sasser worm Mitre, The vulnerability occurs due to the misuse of a vsprintf call Cert, 2. Severity Level of CVE 2. An attacker who successfully exploited the most severe of these vulnerabilities could take complete control of an affected system, including installing programs; viewing, changing, or deleting data; or creating new accounts that have full privileges.

Microsoft, This service is only implemented in the more recent versions of Windows e. However, SMB is also used by many other applications. Many security attacks are a numbers game; that's why the large number of attacks against TCP port is no surprise. Along with ports , and , port is a traditional Microsoft networking port.

This is a core means for communication on a Microsoft-based LAN. If you look at practically any modern Windows host on your network e. Many attacks against port take place via the LAN.

Malware seeking to exploit undersecured Windows systems is a likely source. This is reported to be the most effective workaround and will block traffic on any port. Go to control panel and double click on 'Network and Dialup Connections'.

Right click on the network adapter and click 'Properties'. It is advised not to add any ports to this list and not to select the 'Permit Only' radio button above the 'UDP Ports' label. Conclusion Statistics show that system compromises are on the rise so we must guard against them using the methods available to us. Vulnerability scanners are one tool available for ensuring secure systems.

However, scanners should not be the only weapon in the security arsenal. They should be used in addition to firewalls, intrusion detection tools, good security policies, and all the other defenses noted in this paper. Ideally, scanners should be used as a last defense to complement the security practices already in place. Just keep in mind that a good follow-up plan to correct any vulnerabilities found is just as important as detecting them Cima, Detecting and defending against TCP port attacks.

To exploit this flaw, an attacker would need to send a specially crafted ASN. This particular check sent a malformed NTLM packet and determined that the remote host is not patched.
