For continuous coverage, we push out major Disposable mail security updates every two weeks, keeping our tool up-to-date with new findings, features and improvements sourced from our security researchers and Crowdsource ethical hacker community. Due to confidentially agreements, we cannot publicize all security update releases here but they are immediately added to our scanner and available to all users. This post highlights a few things that we have improved in the last two weeks.
WordPress limit-login-attempts XSS
This WordPress plugin logs the IP-address of users that has multiple failed login attempts. However, in place of recording the actual IP-address, it is possible to log the value of the X-Forwarded-For-header instead.
When the administrator of the WordPress installation later logs into the dashboard the log is visible to them without proper filtering. This means that it is possible to use an XSS-payload as header value. Additional reading.
Expect-CT / Invalid Directive
During a scan of a website we check for several headers that we think improves the security by having set. For some we warn where they are lacking, for others we only warn if it is set to a invalid value.
To the list of checked headers we have now added Expect-CT when it is invalid, as that was submitted to us by a Crowdsource community member. More information about the header.
Spring Boot Path Traversal
Path Traversal bugs have received more and more interest from the security community, which also has lead to more submissions from our Disposable mail Crowdsource white hat hackers. This one was added in the latest release.
One vulnerability leads to another…
After looking at Crowdsource submissions and keeping up with the security community in general, our development team also added security tests to check for CVE-2018-3760: Ruby on Rails Path Traversal and CVE-2018-1271: Spring Path Traversal.
Spring Boot / Health Route Exposure
After the last security update that included submissions related to Spring Boot, our further exploration of this lead to us adding more endpoints that are commonly exposed over the internet.
