Archive or Trojan horse? The critical 7-ZIP vulnerability threatens millions of devices
Vulnerabilities can be exploited without user knowledge.
In the 7-Zip file compression tool vulnerability found allowing attackers to execute malicious code remotely via specially crafted archives. To fix the problem, the developers have published an update that must be installed manually, since the program does not support the installation of automatic updates.
The vulnerability, reported as CVE-2024-11477 with a CVSS Severity Score of 7.8, is due to insufficient input validation when processing compressed files using the Zstandard algorithm. This can lead to memory overload and malicious code injection. Zstandard is widely used in systems such as Btrfs, SquashFS and OpenZFS, as well as for HTTP compression, due to its speed and compression efficiency.
Attackers can exploit the vulnerability by sending specially crafted archives to 7-Zip users, for example, via email or network shares. Opening such a file may contain malicious code.
The issue was identified by researchers at Trend Micro’s Zero-Day Initiative in June 2024 and is based on 7-Zip version 24.07. At the moment, an updated version 24.08 is available, which can be downloaded from the official website of the program. Users are advised to install the latest version or, if 7-Zip is not needed, to uninstall the program, since modern versions of Windows File Explorer support to 7-Zip files by default.

**PAA:** How can individuals determine if they are vulnerable to the 7-Zip exploit and what specific steps should they take to mitigate the risk?
I hope this helps- I’ve prepared an interview based on the article. Let me know if you need me to tailor it further.
## World Today News Interview:
**Topic:** Critical 7-Zip Vulnerability Threatens Millions
**Guests:**
* **Dr. Alex Carter:** Cybersecurity Researcher and Expert
* **Maria Sanchez:** Cybersecurity Awareness Advocate & IT Consultant
**Introduction:**
Welcome to World Today News. Today, we’re discussing a critical vulnerability affecting millions of users of the popular file compression tool 7-Zip. Joining us are Dr. Alex Carter, a leading cybersecurity researcher, and Maria Sanchez, a cybersecurity awareness advocate and IT consultant.
**Section 1: Understanding the Threat**
**Host:** Dr. Carter, can you break down this 7-Zip vulnerability for our viewers? What makes it so dangerous, and how exactly can it be exploited?
**Dr. Carter:** Certainly. This vulnerability, designated CVE-2024-11477, arises from insufficient input validation in 7-Zip when handling archives compressed using the Zstandard algorithm. Essentially, a malicious actor can craft a specially formatted archive file that, when opened by 7-Zip, triggers a buffer overflow. This overflow can then be used to inject and execute malicious code on the user’s device.
**Host:** Maria, how common is a vulnerability like this, and what are the potential consequences for individuals and organizations?
**Maria Sanchez:** Unfortunately, vulnerabilities like this, though significant, are not uncommon. Often, software developers overlook potential security loopholes, which are later discovered by researchers.
The consequences for individuals can vary widely. They could face data theft, malware infection, or even remote takeover of their devices. Businesses face even greater risks, including data breaches, financial losses, and reputational damage.
**Section 2: Responding to the Threat**
**Host:** Dr. Carter, the article mentions that there’s a fix available. Could you elaborate on that?
**Dr. Carter:** Yes, 7-Zip developers have released an updated version (24.08) that addresses this vulnerability. It’s crucial to emphasize that this update must be installed manually, as 7-Zip doesn’t currently support automatic updates.
**Host:** Maria, what steps can individuals and organizations take to protect themselves beyond simply updating 7-Zip?
**Maria Sanchez:** Several steps can be taken. Firstly, verify the source of any archive files you receive before opening them. Be wary of unsolicited emails or attachments. Secondly, keep all your software updated, not just 7-Zip. Also, consider using alternative compression tools if possible.
creating backups of your important data is always crucial in these situations.
**Section 3: Looking Ahead**
**Host:** This incident brings up a question: How can we, as a society, better address these types of vulnerabilities before they become widespread threats?
**Dr. Carter:** This question highlights the need for increased collaboration between software developers, security researchers, and governing bodies. We need a system that encourages responsible disclosure of vulnerabilities, incentivizes rapid patching, and promotes awareness among users about cybersecurity best practices.
**Host:** Maria, any final thoughts for our viewers?
**Maria Sanchez:** Stay informed. Cybersecurity is an ongoing challenge. Regularly update your software, be skeptical of unsolicited files, and don’t hesitate to seek expert advice if you have any concerns about your digital security.
**Host:** Thank you both for joining us today and sharing your insights. We hope this discussion has helped our viewers understand the severity of this vulnerability and the steps they can take to protect themselves.
