CVE-2023-35852: Oisf Suricata

High severity, CVSS 7.5. EPSS: 1.1% chance of exploitation in the next 30 days.

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)
