Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Insufficient verification of data authenticity
EUVDB-ID: #VU52065
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-3448
CWE-ID:
CWE-345 - Insufficient Verification of Data Authenticity
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a DNS Cache Poisoning attack.
The vulnerability exists due to dnsmasq relies only on transmission ID when processing DNS queries and uses the same port for outgoing requests, when configured to given network interface. A remote attacker can guess the random transmission ID to forge a reply and get it accepted by dnsmasq.As a result, an attacker can perform a DNS Cache Poisoning attack.
