In the scan results, administrators receive a list of outdated libraries with the following information: You can scan your systems for outdated shared libraries by running a single command: The Uchecker (short from "userspace checker") works with all modern Linux distributions starting from the 6th versions.

The scanner is free and open-source, distributed under the GNU General Public License. Uchecker was created during the development process of live patching service for shared libraries – KernelCare+. In order to assist the FOSS community and help administrators manage hundreds of servers using shared libraries, KernelCare released Uchecker - a scanner that examines Linux network servers and detects out-of-date libraries used by running processes both on disk and in memory. Identify Libraries that are Still Vulnerable to Attacks After Updates with an Open-Source Scanner Even if the servers are patched manually, if the server is not rebooted, vulnerabilities may still exist in the shared libraries. Sometimes, the servers will not come back properly once they have been rebooted.Īnother problem with reboots is that they can leave a server vulnerable to attack. A server may take time to stabilize after a reboot, causing major disruptions to service. However, rebooting the system involves service degradations and outages. They may not know which services are using which libraries - making rebooting the entire server feel like the easier route to take.

This is why many admins will simply reboot the entire server when they need to update a patch to handle a vulnerability. If one of these libraries is vulnerable, it can be harder to identify because it is not being used directly, so an admin may not know to check the others when looking for vulnerabilities in the system. The more complex the application, the more dependencies the library has.
#WHICH SERVERS ARE VULNERABLE FOR SLOWLORIS ATTACK CODE#
So, a developer may choose one specific library, but it is dependent on another library, which, in turn, is dependent on code in another library. These are a transitive dependency, where the library depends on code in other libraries to run properly. The applications themselves have dependencies on other applications, so they are not as easy to identify as applications that are being directly used. One of the biggest challenges in identifying vulnerable servers is that they often end up in the application indirectly, instead of being directly used in the code. The Challenges of Identifying Vulnerable Libraries
In 2014, when Heartbleed came to light, an estimated 17 percent of the secure web services on the internet were vulnerable. Heartbleed can be a devastating attack because it can impact both the client and the server itself. Hackers can obtain access to the names and passwords of users, cookies, communications, content, and more by exploiting this dangerous vulnerability. "The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software." It attacks a memory handling bug in versions 1.0.1 to 1.0.1f of OpenSSL that allows hackers to decode 64 kilobytes of encrypted data in each heartbeat. The Heartbleed Bug is a major vulnerability in OpenSSL software.

Research has indicated that OpenSSL is the most targeted software in the world, accounting for approximately 19% of hostile activity globally. The open-source software is a library of cryptographic applications that are intended to secure networks, and it is used on the majority of HTTPS websites. OpenSSL patch management is ridden with challenges. The Ponemon survey also indicated that it can take an average of "43 days to see a cyberattack once a patch is released for a critical. A Ponemon survey showed that 88 percent of IT professionals are not solely responsible for patches but rather they usually have to coordinate with other teams, which can delay patching by an average of 12 days.Īnother issue organizations run into is that once a new patch is announced, hackers begin working to exploit the vulnerability before it is patched.

You cannot deploy a patch until it has been tested, and patches often require IT professionals to reconfigure and reboot systems that are difficult to take offline for long. The majority of organizations are not aware of these vulnerabilities until they have experienced a breach, at which point it is frustrating to learn that deploying a simple patch could have prevented the breach altogether. Patch management can be a complex and time-consuming process, and because of this, patches to fix vulnerabilities may not be applied before a hacker is able to breach an organization's security.
