Directory Traversal Vulnerability in 7-Zip by 7-Zip Team

CVE-2025-11001

What is CVE-2025-11001?

CVE-2025-11001 is a directory traversal vulnerability identified in the popular file archiving software 7-Zip, which is widely used for compressing and decompressing files across various operating systems. This vulnerability arises from the way 7-Zip handles symbolic links within ZIP file structures, allowing remote attackers to exploit this flaw by crafting malicious ZIP files. When an affected user interacts with such a ZIP file, the software can be tricked into traversing to unintended directories, thus granting attackers the ability to execute arbitrary code on the system using the permissions of the user or service account executing 7-Zip. This can have serious consequences, particularly since 7-Zip is often used to handle sensitive files, leading to potential data breaches and unauthorized access to critical systems.

Potential impact of CVE-2025-11001

1. Remote Code Execution: The primary risk associated with CVE-2025-11001 is the ability for attackers to execute arbitrary code remotely. This could allow them to take control of affected systems, install malware, or perform actions that would compromise the integrity and confidentiality of the data.

2. Data Exposure: Since 7-Zip is commonly used to manage files that may contain sensitive or confidential information, a successful exploitation could lead to unauthorized access to files, resulting in data leaks that can have legal and financial ramifications.

3. Service Account Compromise: The vulnerability allows attackers to execute code in the context of the service account under which 7-Zip is running. This could elevate an attacker's privileges, enabling them to navigate the network, access other resources, and potentially spread to additional systems within an organizational environment.
