Worms form a proper subset of a type of malicious software or malware for short known generally as computer viruses , the overarching term for self-replicating malware of any sort. This means that most RCE bugs are, in theory at least, wormable , meaning that they could potentially be exploited to initiate a chain of automatic, self-spreading and self-sustaining malware infections. As you can imagine, some classes of RCE bug are considered much more wormable than others, especially bugs that can be triggered directly via a simple network interaction.
That was a risk of considerable concern in the recent Log4Shell saga , where a single booby-trapped web request with some curious but otherwise unexceptionable ASCII text in it could trigger arbitrary remote code execution. Does the attack depend on you having a known web server such as Microsoft IIS Internet Information Services already installed and activated?
The last point above makes it clear that that you may have any number of apps in use — perhaps without realising it — that provide an HTTP-based interface via HTTP. Simply put: you could, in theory, have apps installed, even on a desktop or laptop computer, that provide some sort of web-based interface that is serviced by the HTTP. The silver lining, for some users at least, is that the part of HTTP. If you are truly unable to patch right away, and if you know that you are not running or at least do not intend to run any web-based software that uses HTTP.
After a reboot, you can check the status of HTTP. Note that we have tested this workaround in only the most cursory fashion. Three of these vulnerabilities point to a basic lack of good housekeeping: Missing Authentication , Missing Authorization , and Missing Encryption. And three others have to do with erroneous or ill-advised use of application defense techniques, including Incorrect Authorization , Incorrect Permission Assignment , and Improper Restriction of Excess Authentication Attempts.
Resource management involves creating, using, transferring, and destroying system resources such as memory. Proper, secure management resource is necessary for effective application defense. These application vulnerabilities range from the classic Buffer Overflow and Path Traversal to the more-sci-fi-sounding Inclusion of Functionality from Untrusted Control Sphere and the ominously named Use of Potentially Dangerous Function.
Client-side issues are more difficult to fix unless precautions are thought of while designing the user interface. Modern browsers are more protective of applications, but many applications still support backward compatibility to include a wider range of users, older versions of browsers, and insecure client computers.
Therefore, client-side components need to implement security in the design phase when considering these issues. Server-side components can be protected by implementing countermeasures during the design and coding phases of application development. An obsolete server software such as Apache Tomcat 3.
These should be immediately upgraded to the latest version. Mobile systems such as smart phones and tablets that use varied operating systems and security designs are more prevalent than web applications these days. These devices, and the applications running on these devices, may pose tremendous risks for the sensitive data they store.
Business emails and personal contacts may be exposed to untrusted networks. These applications also interact with many supporting services. Devices can be stolen. Malware can be installed. Most are evolutionary improvements on existing exploits. With the advent of the Common Malware Enumeration CME standard, there will be one shared, neutral indexing capability for malware but that will take years - probably more than five years, like the CVE standard which is still just starting to catch on, since its inception in by Mitre, now funded by the U.
Department of Homeland Security. It is crucial today to prevent vulnerabilities across the enterprise and remove these CVEs - these security holes in your desktops, laptops and servers. They all exploited one CVE - one minor hole. Just take a look at the U. If you just purchased a Cisco router or a Linksys wireless router or Solaris version 9 running Netscape Enterprise, or anything else that plugs into a network, type in the name of the system in the NVD and see how many CVEs vulnerabilities you find.
Want to see the top 20 exploited vulnerabilities? If you have one of these holes, close it as quick as you can or you can expect to be taken advantage of when you least expect it. Hackers, viruses and worms cause billions in damages by using CVEs against us, and the damages are growing annually.
