What an attacker can do

An unauthenticated, remote attacker could cause the disclosure of possible sensitive data or cause the Snort 3 Detection Engine to crash. Vendor/CNA’s CVSS 3.1 assessment (base score 6.5/10) rates confidentiality and availability impact as low; integrity impact as none. NVD’s CVSS 3.1 assessment (base score 9.1/10) rates confidentiality and availability impact as high; integrity impact as none.
