Highlights for March 2020

Cross site scripting and Cross Site Request Forgery vulnerabilities were most prevalent this month. Attackers took advantage of the lack of restrictions in critical functions and issues surrounding user input data sanitization.

Ongoing Campaign Targets Plugin Vulnerabilities

An ongoing malicious campaign that we’ve been actively tracking since early 2019 continues targeting new plugin vulnerabilities to inject malicious domains.

Multiple Plugins Affected by an Old Vulnerability in PHPUnit

As seen in January attackers are continuing to leverage an RCE in PHPUnit along with several plugin vulnerabilities found in the past month.

Unpatched versions of PHPUnit prior to 4.8.28 and 5.6.3 allow remote attackers to execute arbitrary PHP code via HTTP POST data.
