Microsoft has warned companies and government agencies about a critically exploited vulnerability in their server software. This vulnerability can be exploited by the attackers to get unauthorized remote system access. Applying released security updates as soon as possible is required to prevent the threat.

Highlights:

• An actively exploited critical vulnerability exists in Microsoft server software.
• Businesses and government organizations are the primary targets.
• Exploitation enables remote attackers to gain system control.
• Microsoft has released critical security patches addressing the flaw.
• Organizations must apply these patches immediately.

This is a critical bug that permits unauthorized remote attackers to run arbitrary code in affected server systems of Microsoft. Active exploitation is actually reported by security researchers. The severity of the flaw is its ease to exploit and the high access level it consists of. It is necessary to combat this major weakness in order to avoid compromisation.

In order to cure this critical problem Microsoft has introduced non-scheduled security updates. The company says the only remedy it takes into consideration is using these patches. It is the responsibility of the system administrators to ensure that such updates are deployed in all vulnerable servers as soon as possible. It is important to patch as soon as possible since the risk of breaching a network through this vulnerability is extremely high.

Susceptible unpatched systems to this extreme vulnerability are at great risk of being deeply compromised, possibly losing its data and disrupting the network, especially by critical infrastructure. Microsoft goes to the extent of setting it that patching that is not immediately affected is not an option. Organizations should give this critical vulnerability the most important priority in order to safe sail their systems.
