Using Foxit Reader? You might be vulnerable to network breaches
Desktop Central | August 25, 2017 | 2 min read
Cybersecurity and cyberattacks have become prominent topics lately. No matter how much you secure your network, vulnerabilities continue to emerge for different operating systems and applications. Most recently, security professionals have discovered two critical vulnerabilities in a third-party PDF reading application called Foxit Reader. These vulnerabilities allow hackers to execute arbitrarily-defined code on a user‘s computer when Foxit Reader is used without Safe Reading Mode enabled.
Two critical zero–day vulnerabilities
On August 17th, researchers Steven Seeley and Ariele Caltabiano discovered two vulnerabilities in Foxit Reader:
1. CVE-2017-10951, which acts as a command injection bug that resides in the app.launchURL function and executes strings provided by hackers. This vulnerability is mainly due to improper validation.
2. CVE-2017-10952, which exists in the saveAs function and allows hackers to execute an arbitrarily–specified file on user computers. If the arbitrary file is modified, then hackers can modify anything on the end user’s computer. Steven Seeley has tested a proof of concept and published it on Zero Day Initiative.
How can you keep Foxit Reader safe?
1.Take precautions: Avoid downloading attachments from email addresses you don’t know. Opening a PDF from a nefarious sender could compromise your entire system.
3.Employ automatic patch management: Doing all the ground work manually is tiresome and complicated, especially since the number of vulnerabilities per application continually increases. Regularly updating your network is one of the best ways to remain free from zero-day vulnerabilities. Stay vigilant by employing patch management software like Desktop Central, which manages and deploys patches automatically.
