About Authentication Bypass - PAN-OS (CVE-2024-0012) vulnerability

About Authentication Bypass – PAN-OS (CVE-2024-0012) vulnerability. An unauthenticated attacker with network access to the Palo Alto device web management interface could gain PAN-OS administrator privileges to perform administrative actions, tamper with the configuration, or exploit other authenticated vulnerabilities. Firewalls of the PA, VM, CN series and the Panorama management platform are vulnerable. The vendor recommends restricting access to the management web interface to trusted internal IP addresses only.

🔻 On November 8, a Palo Alto bulletin was released
🔻 On November 15, signs of attacks were noticed, labeled as “Operation Lunar Peek”
🔻 On November 18, the vulnerability was added to the CISA KEV
🔻 On November 19, watchTowr Labs released a post with technical details (“supply the off value to the X-PAN-AUTHCHECK HTTP request header, and the server helpfully turns off authentication”) 😏 and exploits soon appeared on GitHub

The severity of the Remote Code Execution - Microsoft SharePoint (CVE-2024-38094) vulnerability has increased

The severity of the Remote Code Execution – Microsoft SharePoint (CVE-2024-38094) vulnerability has increased. It was fixed as part of the July Microsoft Patch Tuesday (July 9).

SharePoint is a popular platform for corporate portals. According to the Microsoft bulletin, аn authenticated attacker with Site Owner permissions can use the vulnerability to inject arbitrary code and execute this code in the context of SharePoint Server.

On July 10, a repository with a PoC exploit for this vulnerability appeared on GitHub, as well as a video demonstrating how an attacker can launch processes on the attacked SharePoint server. A GitHub search by CVE number does not find a repository with the exploit, but a link is available in the The Hacker News article. Exploit also relates to the July SharePoint RCEs CVE-2024-38023 and CVE-2024-38024.

On October 22, the vulnerability was added to the CISA KEV, which means it was exploited in the wild.

Trending vulnerabilities of July according to Positive Technologies.

The SecLab film crew went on vacation. Therefore, there was a choice: to skip the episode of “In the trend of VM” about the July vulnerabilities, or to make a video myself. Which is what I tried to do. And from the next episode we will return to SecLab again.

📹 Video “In The Trend of VM” on YouTube
🗞 A post on Habr (rus) a slightly expanded script of the video
🗒 A compact digest (rus) on the official PT website

List of vulnerabilities:

🔻 00:33 Spoofing – Windows MSHTML Platform (CVE-2024-38112)
🔻 02:23 RCE – Artifex Ghostscript (CVE-2024-29510)
🔻 03:55 RCE – Acronis Cyber Infrastructure (CVE-2023-45249)

Remote Code Execution – Acronis Cyber Infrastructure (CVE-2023-45249)

Remote Code Execution - Acronis Cyber Infrastructure (CVE-2023-45249)

Remote Code Execution – Acronis Cyber Infrastructure (CVE-2023-45249). Due to the default passwords used, a remote unauthenticated attacker can gain access to an Acronis Cyber ​​Infrastructure (ACI) server and execute arbitrary code.

ACI is a hyperconverged platform for storage, backup, computing, virtualization and networking.

🔻 Patches that fix this vulnerability were released on October 30, 2023 (❗️).
🔻 After 9-10 months, on July 24 of this year, Acronis noted in a bulletin that the vulnerability was exploited in the wild. The purpose of exploitation was to install a cryptominer. On July 29, the vulnerability was added to the CISA KEV.

Some sources report 20,000 service providers using ACI. I have not found any confirmation of this. Perhaps there is confusion with Acronis Cyber ​​Protect. However, there are probably quite a few large companies using ACI. If you work for such a company, be sure to pay attention.

“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. 🙂

The criticality of the Elevation of Privilege - Windows Error Reporting Service (CVE-2024-26169) vulnerability has increased

The criticality of the Elevation of Privilege – Windows Error Reporting Service (CVE-2024-26169) vulnerability has increased. If exploited successfully, the attacker gains SYSTEM privileges. The vulnerability was fixed in Microsoft’s March Patch Tuesday. As often happens, no one highlighted this vulnerability back then. 🤷‍♂️

However, 3 months later, on June 12, Symantec researchers reported attacks related to the famous Black Basta ransomware, in which exploits for this vulnerability were used. If we believe the compilation timestamps, these exploits were created long before the release of Microsoft’s patches, in February 2024 or even December 2023. Of course, attackers could fake them, but why would they do that? 🤔

On June 13, the vulnerability was added to CISA KEV. The exploit is not yet publicly available.

The moral is the same: vulnerability prioritization is good, but regular unconditional patching is better.
