Title source: llm
STIX 2.1

Exploitation Summary

CVE-2025-11001 has been observed exploited in the wild (reported by VulnCheck KEV). EIP tracks 7 public exploits from researchers including Mohammed Idrees Banyamer, pacbypass, mbanyamer.

AI-analyzed exploit summary This Python script generates a malicious ZIP archive exploiting CVE-2025-11001 in 7-Zip < 25.00. It crafts a symlink entry with directory traversal sequences to drop a payload in an arbitrary location when extracted, leading to RCE or LPE.

Description

7-Zip ZIP File Parsing Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. Interaction with this product is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the handling of symbolic links in ZIP files. Crafted data in a ZIP file can cause the process to traverse to unintended directories. An attacker can leverage this vulnerability to execute code in the context of a service account. Was ZDI-CAN-26753.
