Netexec · Netexec · CVE-2026-27884
**Name of the Vulnerable Software and Affected Versions**
NetExec versions prior to 1.5.1
**Description**
NetExec is a network execution tool. The spider plus module does not properly handle file paths when saving files from SMB shares, specifically failing to account for path traversal characters like `../` in Linux SMB shares. This allows an attacker to craft a filename containing these characters, potentially leading to arbitrary file overwrites or creation during file downloads performed by the spider plus module. The issue is addressed in version 1.5.1.
**Recommendations**
Versions prior to 1.5.1 should be updated to version 1.5.1 or later.
As a workaround, avoid running spider plus with DOWNLOAD=true against targets.
