Low risk29th percentile - higher than 29% of all known CVEs
Summary
Relative path traversal vulnerability in DNS Server allows an authorized attacker to execute code over an adjacent network.
Risk Assessment
An attacker could take control of the DNS server and execute arbitrary code, compromising network service integrity and availability.
Recommendation
Apply the latest security updates provided by the DNS server vendor and restrict trusted adjacent networks.
