In-The-Wild & Disclosed CVEs

CVE-2023-50868

The only disclosed vulnerability we have this month, is CVE-2023-50868, a DNSSEC protocol level vulnerability that can lead to denial of service. The vulnerability is a CPU Exhaustion related to the Closest Encloser Proof in NSEC3, a mechanism within DNSSEC. NSEC3 is the improved version of NSEC, a technology that helps prevent against DNS Cache Poisoning for non-existent records (among other things) by providing authenticated denial of existence. In other words, it authoritatively proves that a record does not exist. Since NSEC could be used for domain enumeration, NSEC3 was introduced with the inclusion of hashing techniques. An attacker can cause excessive SHA-1 computations leading to the CPU Exhaustion. Since this is a protocol level vulnerability, other DNS solutions including PowerDNS, Bind, and dnsmasq are impacted and have updates available. According to most vendors, this vulnerability can be mitigated by turning DNSSEC validations off. Microsoft has reported this vulnerability as Exploitation Less Likely.
