Brizy WordPress Plugin Exploit Chains Allow Full Site Takeovers

Vulnerabilities in the Brizy Page Builder plugin for WordPress sites could be chained together to allow attackers to completely take over a website, according to researchers.
Brizy (or Brizy – Page Builder) has been installed on more than 90,000 sites. It’s billed as an intuitive website builder for those without technical skills. It comes with a collection of more than 500 pre-designed blocks, maps and video integration and drag-and-drop design functionality. According to researchers, it also came with a stored cross-site scripting (XSS) issue and an arbitrary file-upload vulnerability prior to version 2.3.17.
These two bugs, when combined with another flaw that allows authorization bypass and privilege escalation, can become dangerous, Wordfence researchers cautioned.
“During a routine review of our firewall rules, we found traffic indicating that a vulnerability might be present in the Brizy – Page Builder plugin, though it did not appear to be under active attack,” researchers at Wordfence explained in a Wednesday posting. “This led us to discover two new vulnerabilities as well as a previously patched access-control vulnerability in the plugin that had been reintroduced.”
The two fresh bugs can both be chained with the re-introduced access control vulnerability to allow complete site takeover, researchers explained. In a combo with the stored XSS bug, any logged-in user would be able to modify any published post and inject malicious JavaScript to it. A pairing with the other bug could meanwhile allow any logged-in user to upload potentially executable files and achieve remote code execution.

It’s a high-severity issue that stems from a lack of proper authorization checks, according to Wordfence, allowing attackers to modify posts.
Researchers noted that the plugin uses a pair of administrator functions for a wide variety of authorization checks, and “any user that passed one of these checks was assumed to be an administrator.” They added, “being logged in and accessing any endpoint in the wp-admin directory was sufficient to pass this check.”
The upshot of this is that all logged-in users, such as subscribers to a newsletter, were allowed to modify any post or page that had been created or edited with the Brizy editor, even if it had already been published.
“While this vulnerability might only be a nuisance on its own, allowing attackers to replace the original contents of pages, it enabled two additional vulnerabilities that could each be used to take over a site,” according to Wordfence’s analysis.

Because it’s a stored XSS bug, rather than a reflected one, victims need only visit the infected page in order to be attacked.
On its own, the bug allows a lower-privileged user (such as a contributor or subscriber) to add JavaScript to an update request, which would then be executed if the post were viewed or previewed by another u[...]

I got hacked with 2 step verification on and I don't know how to stop any attempts such as this
There was a Linux system connected to my account so I removed it and it was 7 days ago so on 7th Oct which is bad but there was no notification for 2 step verification which is worse , help me block further attempts such as these

Kitploit
Kitploit – Maintenance in Progress
Kitploit is temporarily under maintenance. We’ll be back shortly with improvements.
Installation
The latest stable release of XMap is version 1.0.0 and supports Linux, macOS, and BSD. We recommend installing XMap from HEAD rather than using a distro package manager (not supported yet). Instructions on building XMap from source can be found in INSTALL (https://github.com/idealeer/xmap/blob/master/INSTALL.md).
Usage
A guide to using XMap can be found in our GitHub Wiki (https://github.com/idealeer/xmap/wiki). Simple commands and options to using XMap can be found in USAGE (https://github.com/idealeer/xmap/blob/master/src/xmap.1.ronn).
Paper
Fast IPv6 Network Periphery Discovery (https://www.kitploit.com/search/label/Discovery) and Security Implications. Abstract. Numerous measurement researches have been performed to discover the IPv4 network security issues by leveraging the fast Internet-wide scanning techniques. However, IPv6 brings the 128-bits address space and renders brute-force (https://www.kitploit.com/search/label/Brute-force) network scanning impractical. Although significant efforts have been dedicated to enumerating active IPv6 hosts, limited by technique efficiency and probing accuracy, large-scale empirical measurement studies under the increasing IPv6 networks are infeasible now. To fill this research gap, by leveraging the extensively adopted IPv6 address allocation strategy, we propose a novel IPv6 network periphery discovery approach. Specifically, XMap, a fast network scanner, is developed to find the periphery, such as a home router. We evaluate it on twelve prominent Internet service providers and harvest 52M active peripheries. Grounded on these found devices, we explore IPv6 network risks of the unintended exposed security services and the flawed traffic routing strategies. First, we demonstrate the unintended exposed security services in IPv6 networks, such as DNS, and HTTP, have become emerging security risks by analyzing 4.7M peripheries. Second, by inspecting the periphery’s packet routing strategies, we present the flawed implementations of IPv6 routing protocol affecting 5.8M router devices. Attackers can exploit this common vulnerability (https://www.kitploit.com/search/label/Vulnerability) to conduct effective routing loop attacks, inducing DoS to the ISP’s and home routers with an amplification factor of >200. We responsibly disclose those issues to all involved vendors and ASes and discuss mitigation solutions. Our research results indicate that the security community should revisit IPv6 network strategies immediately. Authors.

DMZ servers to Internal Domain Controllers?
https://www.reddit.com/r/Pentesting/comments/q7xb2w/dmz_servers_to_internal_domain_controllers/
Hi all, I work as a Penetration tester and as part of our testing we conduct firewall reviews. I regularly see companies extending their internal domain into their DMZ and firewall rules allowing DMZ server to smb directly to Internal Domain Controllers. Why? I know this to be bad practice and shouldn't be done however what is the solution? What should they be doing? Read only Domain controller? Separate DMZ domain? But what if there are DMZ servers that staff need to use their AD account to authenticate to like reverse proxy for RDP or email? Any help to clear this up in my mind is greatly appreciated! Thanks all! submitted by /u/HazardNet (https://www.reddit.com/user/HazardNet)

Grounded on these found devices, we explore IPv6 network risks of the unintended exposed security services and the flawed traffic routing strategies. First, we demonstrate the unintended exposed security services in IPv6 networks, such as DNS, and HTTP, have become emerging security risks by analyzing 4.7M peripheries. Second, by inspecting the periphery’s packet routing strategies, we present the flawed implementations of IPv6 routing protocol affecting 5.8M router devices. Attackers can exploit this common vulnerability to conduct effective routing loop attacks, inducing DoS to the ISP’s and home routers with an amplification factor of >200. We responsibly disclose those issues to all involved vendors and ASes and discuss mitigation solutions. Our research results indicate that the security community should revisit IPv6 network strategies immediately.

GoPhish tracking email malfunction!
https://www.reddit.com/r/redteamsec/comments/q7zzsf/gophish_tracking_email_malfunction/
Hello everyone, I'm doing local phishing simulation with gophish but cant seem to track whenever I open the email. Quick lab guide: [SERVER SIDE] GoPhish running on kali and port 80 is exposed to the whole /24 network. GoPhish is setup with gmail smtp with less secure apps enabled. Tracker image is added to every email template I use. [CLIENT SIDE] Windows 10 fully pathed and updated, running outlook 2016 and gmail through web browser. [OBSERVATION] When phishing emails are opened from web (gmail) all of the images load but still gophish does not note the action. When phishing emails are opened from Outlook 2016 the images do not render unless you click pop up > download all images and then gophish notes this action and counts email to be opened. [QUESTION] Is there a way to bypass this pop-up action and gmail security to count email being open without performing additional actions? Thanks :) submitted by /u/luzunov (https://www.reddit.com/user/luzunov)
