CVE-2022-33989

CVE-2022-33989 concerns dproxy-nexgen (dproxy nexgen), which uses a static UDP source port that is chosen randomly only at boot for upstream DNS queries. The limited entropy enables DNS cache poisoning since traffic injection becomes easier without a fresh, per-query port randomization. Connected...

CVE-2022-33990

CVE-2022-33990 affects dproxy-nexgen (dproxy nexgen). The issue stems from misinterpretation of special domain name characters causing domain names and their IP addresses to be cached in the misinterpreted form, enabling cache poisoning. The CVSS 3.1 base score is 7.5 (Network, Low attack complex...

CVE-2022-33988

dproxy-nexgen aka dproxy nexgen re-uses the DNS transaction id TXID value from client queries, which allows attackers able to send queries to the resolver to conduct DNS cache-poisoning attacks because the TXID value is known to the attacker...

CVE-2022-33988

CVE-2022-33988 affects dproxy-nexgen (DNS proxy). The issue is the reuse of the DNS TXID from client queries, enabling an attacker who can send queries to the resolver to perform DNS cache poisoning. Exploitation status is not detailed in the provided documents; no concrete patch/version remediat...

CVE-2022-34294

The CVE-2022-34294 entry concerns totd 1.5.3, a small DNS proxy nameserver. The issue is that upstream DNS queries use a fixed UDP source port, providing insufficient entropy and enabling DNS cache poisoning. Affected component: totd 1.5.3. Root cause: fixed UDP source port in upstream queries to...
