CVE-2022-33991

CVE-2022-33991 affects dproxy-nexgen (dproxy nexgen), a DNS proxy/cache. The root issue is that it forwards and caches DNS queries with the CD (Check Disabled) bit set to 1, which disables DNSSEC protection from upstream resolvers. The CVE details provided show a CVSS v3.1 base score of 5.3 (Netw...

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-2022-33989

dproxy-nexgen aka dproxy nexgen uses a static UDP source port selected randomly only at boot time in upstream queries sent to DNS resolvers. This allows DNS cache poisoning because there is not enough entropy to prevent traffic injection attacks...

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-2022-33988

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-2022-33988

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...
