Last modified

CVE-2023-35852 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 1.10% chance of exploitation in the next 30 days.
