Description

In Suricata before 6.0.13 (when there is an adversary who controls an external source of rules), a dataset filename, that comes from a rule, may trigger absolute or relative directory traversal, and lead to write access to a local filesystem. This is addressed in 6.0.13 by requiring allow-absolute-filenames and allow-write (in the datasets rules configuration section) if an installation requires traversal/writing in this situation.

Affected products

OISF suricata: before 6.0.13 — fixed in 6.0.13

How to fix

Upgrade to a fixed version: OISF suricata 6.0.13. Check the vendor advisory for mitigations.
