I transformed my English-language site avleonov.com

I transformed my English-language site avleonov.com

I transformed my English-language site avleonov.com. While my Russian-language site avleonov.ru was intended as a mirror of my Telegram channel @avleonovrus, I wasn’t sure how to move forward with the English-language site. 🤔

I’ve been running it since 2016. For a long time, it was my main VM blog. Since February 2020, I have been making posts there exclusively with videos. 🪧 I have released 94 videos. But over time, I grew tired of this format. 😮‍💨 It was easier and more engaging to create videos in Russian (starting with “Прожекторе по ИБ“, and later in “В тренде VM“) and translate them into English when needed.

Since March 2024, the English site had no updates. New posts appeared exclusively on the Telegram channel @avleonovcom. 🤷‍♂️ So, I decided to make the site a mirror of this channel. 🪞

✅ I updated the scripts and uploaded 117 Telegram posts (since March 2024) to the site, leaving the earlier content as is.

About Remote Code Execution - XWiki Platform (CVE-2024-31982) vulnerability

About Remote Code Execution – XWiki Platform (CVE-2024-31982) vulnerability. XWiki is a free open-source wiki platform. Its main feature is simplified extensibility. XWiki is often used in corporate environments as a replacement for commercial Wiki solutions (such as Atlassian Confluence).

A vulnerability with CVSS Base Score 10, published on April 10, allows attackers to execute arbitrary code via queries in the XWiki database search interface. This interface is available to all users by default and complements the regular XWiki search. If it is not needed, it can be disabled by removing the Main.DatabaseSearch page. The vulnerability is fixed in XWiki versions 14.10.20, 15.5.4 and 15.10RC1.

An exploit PoC was provided by XWiki developers in their vulnerability bulletin. 🤷‍♂️ Functional scripts for exploiting this vulnerability have been available on GitHub since June 22.

If your organization uses XWiki, be sure to pay attention.

What is known about the Spoofing - Windows MSHTML Platform (CVE-2024-43573) vulnerability from the October Microsoft Patch Tuesday?

What is known about the Spoofing – Windows MSHTML Platform (CVE-2024-43573) vulnerability from the October Microsoft Patch Tuesday? In fact, just that it is being exploited in the wild. There are no write-ups or public exploits yet. The Acknowledgements section in the Microsoft bulletin is empty. It is not clear who reported it and from whom we can expect details.

ZDI suggested that this could be an additional fix for a similar July vulnerability Spoofing – Windows MSHTML Platform (CVE-2024-38112). The vulnerability type and component are the same. The July vulnerability was about “.url” file handling and was exploited by the APT group Void Banshee to install the Atlantida Stealer malware. Attackers may have bypassed the initial fix, prompting Microsoft to release a new patch. So far, this is only an assumption. But the vulnerability shouldn’t be ignored despite its low CVSS Base score (6.5).
