Enlarge / One of two publicly available exploits for a critical Apache Struts vulnerability. (credit: Kevin Beaumont ) In a string of attacks that have escalated over the past 48 hours, hackers are actively exploiting a critical vulnerability that allows them to take almost complete control of Web servers used by banks, government agencies, and large Internet companies. The code-execution bug resides in the Apache Struts 2 Web application framework and is trivial to exploit. Although maintainers of the open source project patched the vulnerability on Monday , it remains under attack by hackers who are exploiting it to inject commands of their choice into Struts servers that have yet to install the update, researchers are warning. Making matters worse, at least two working exploits are publicly available. “If you run it against a vulnerable application, the result will be the remote execution of commands with the user running the server,” Vicente Motos wrote of one of the exploits in a post published late Wednesday afternoon on the Hack Players website. “We have dedicated hours to reporting to companies, governments, manufacturers, and even individuals to patch and correct the vulnerability as soon as possible, but the exploit has already jumped to the big pages of ‘advisories,’ and massive attempts to exploit the Internet have already been observed.” Read 8 remaining paragraphs | Comments
