Qualys introduces TruRisk Eliminate for augmented Patch Management

Qualys introduces TruRisk Eliminate for augmented Patch Management

Qualys introduces TruRisk Eliminate for augmented Patch Management. Qualys didn’t wait until the event and published a blog post. What they presented is an implementation of workarounds.

In the screenshot of TruRisk Eliminate we see a filtered list of vulnerabilities on assets, the criticality of vulnerabilities in the form of QDS, the Remediations and Mitigations columns.

🔹 Remediations – installing a patch or installing a patch with reconfiguration.

🔹 Mitigations – workarounds that neutralize the vulnerability instead of patching: changing the registry key, changing the config, removing the application, blocking the port, isolating the device, etc.

And there is a button to perform an action on the asset (using an agent) with a choice of Remediations/Mitigations option.

It’s a logical step. Since they gave the ability to patch, why not give the ability to apply workarounds. But Qualys will have a lot of difficulties with this. 🫣

“The Mystery of the Hole”: Remote Code Execution – Internet Explorer (CVE-2012-4792)

The Mystery of the Hole: Remote Code Execution - Internet Explorer (CVE-2012-4792)

“The Mystery of the Hole”: Remote Code Execution – Internet Explorer (CVE-2012-4792). Yesterday, an old vulnerability “CDwnBindInfo” from 2012 was added to CISA KEV: the user opens a malicious website in MS Internet Explorer 6–8 and the attacker gets RCE on user’s host. The vulnerability has been actively exploited since the end of 2012 as 0day in watering hole attacks on US organizations. In particular, the malicious code was placed on the hacked Council on Foreign Relations (CFR) website.

Why was the vulnerability added to CISA KEV only now?

🔹 New attacks on legacy systems (Win XP/ Vista/7, WinServer 2003/2008) were discovered? 🤪 It’s unlikely.

🔹 They saw a vulnerability with confirmed incidents, but it wasn’t in CISA KEV, so they added it? More likely, but why only this vulnerability? 🧐

🔹 There was no formal excuse for urgently updating found legacy systems? A bit strange. 🤷‍♂️

Let’s wait for updates. 🙂

About the “EvilVideo” vulnerability in Telegram for Android

About the EvilVideo vulnerability in Telegram for Android

About the “EvilVideo” vulnerability in Telegram for Android. The post was published on the ESET blog. They stated that the exploit is for sale on the Dark Net.

🔻 The attacker creates a payload, which is displayed in Telegram for Android not as a file, but as a video preview. By default, media files in Telegram are downloaded automatically when the user sees a message in a chat. This payload will also be downloaded automatically as well.
If the user clicks on the preview, he sees a Telegram error asking him to use an external media player.
If the user agrees, an attempt is made to install the APK.
If the user allows the installation of APK from Telegram and clicks on the preview again, a window appears to confirm the installation of the application.
If the user presses “install”, the malware installs. 👾
🎞 There is a video demo.

🔻 Fixed in 10.14.5, older versions are vulnerable.

This is far from 0click, but with good social engineering, the efficiency can be high.

What is known about Spoofing – Windows MSHTML Platform (CVE-2024-38112) from the July Microsoft Patch Tuesday?

What is known about Spoofing - Windows MSHTML Platform (CVE-2024-38112) from the July Microsoft Patch Tuesday?

What is known about Spoofing – Windows MSHTML Platform (CVE-2024-38112) from the July Microsoft Patch Tuesday?

🔻 According to Check Point, attackers use special “.url” files with icons that look like PDF documents. If the user clicks on the file and ignores 2 uninformative warnings, then a malicious HTA application is launched in the outdated Internet Explorer browser built into Windows. 😱 Why in IE? This is all due to the processing of the “mhtml:” prefix in the “.url” file. The July update blocks this. 👍

🔻 Check Point found “.url” samples that could date back to January 2023. According to Trend Micro, the vulnerability is exploited by the APT group Void Banshee to install the Atlantida Stealer malware and collect passwords, cookies and other sensitive data. Void Banshee add malicious “.url” files to archives with PDF books and distribute them through websites, instant messengers and phishing.

Remote Code Execution – Bitrix (CVE-2022-29268) and Jet CSIRT deface case

Remote Code Execution - Bitrix (CVE-2022-29268) and Jet CSIRT deface case

Remote Code Execution – Bitrix (CVE-2022-29268) and Jet CSIRT deface case.

🔻 The vulnerability is in the “Rejected” status in NVD, although its exploitability has been confirmed. 🤷‍♂️ What is it about? CMS Bitrix can be deployed from the “1C-Bitrix: Virtual Machine” image. Then it is configured in the web setup interface (without authentication). At a certain step there is an option “Upload backup”. Instead of a backup, you can upload a web shell there and it will be installed. 🫠

🔻 What is the risk? Surely no one will expose the initial setup interface to the Internet? 🤔 But people do it, Google dork is available.

🔻 This happened in the Jet CSIRT website deface case as well. In November 2023, the setup interface was exposed for 3 days. The attackers found it and installed the web shell. 🤷‍♂️

Jet states that Bitrix does not consider this to be a vulnerability in the setup interface. So the recommendation: don’t make it accessible from the Internet. 😅🤡
