GHSA-2XX4-JJ5V-6MFF
Vulnerability from github – Published: 2023-08-04 17:27 – Updated: 2023-10-20 17:45Overview
We have identified and addressed a security issue in the Nuclei project that affected users utilizing Nuclei as Go code (SDK) running custom templates. This issue did not affect CLI users. The problem was related to sanitization issues with payloads loading in sandbox mode.
Details
In the previous versions, there was a potential risk with payloads loading in sandbox mode. The issue occurred due to relative paths not being converted to absolute paths before doing the check for sandbox flag allowing arbitrary files to be read on the filesystem in certain cases when using Nuclei from Go SDK implementation.
This issue has been fixed in the latest release, v2.9.9. We have also enabled sandbox by default for filesystem loading. This can be optionally disabled if required.
The -sandbox option has been deprecated and is now divided into two new options: -lfa (allow local file access) which is disabled by default and -lna (restrict local network access) which can be optionally disabled by user. The -lfa allows file (payload) access anywhere on the system (disabling sandbox effectively), and -lna blocks connections to the local/private network.
Affected Versions
This issue affected all versions of Nuclei prior to v2.9.9.
Patches
We recommend all users upgrade to the latest version, v2.9.9, which includes the security fix.
