CWE-406
Insufficient Control of Network Message Volume (Network Amplification)
Monthly
Unbounded echo flow responses in Apache Qpid Broker-J (all versions through 10.0.1) allow an authenticated AMQP 1.0 client to exhaust broker resources and cause denial of service by flooding the broker with unanswered echo flow frames. The root cause is absent rate-limiting on echo flow response logic in the qpid-broker-plugins-amqp-1-0-protocol plugin. No public exploit code or CISA KEV listing has been identified; the vendor has released a fix in version 10.1.0.
Quota bypass in NLnet Labs Unbound 1.22.0 through 1.25.1 allows a remote unauthenticated client to cause the resolver to send more upstream DNS packets per query than the operator-configured 'max-global-quota' limit. A single crafted query for a deeply nested hostname under a DNSSEC-signed parent zone triggers excessive recursive DNSSEC validation traffic, effectively neutralizing a security control designed to suppress upstream amplification. No public exploit code has been identified and the vulnerability is not listed in CISA KEV at time of analysis.
nptd-rs is a tool for synchronizing your computer's clock, implementing the NTP and NTS protocols. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
IBM MQ 9.2 LTS, 9.3 LTS, and 9.3 CD Internet Pass-Thru could allow a remote user to cause a denial of service by sending HTTP requests that would consume all available resources. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
A PAN-OS URL filtering policy misconfiguration could allow a network-based attacker to conduct reflected and amplified TCP denial-of-service (RDoS) attacks. Rated high severity (CVSS 8.6), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
An incomplete fix for CVE-2020-12662 was shipped for Unbound in Red Hat Enterprise Linux 7, as part of erratum RHSA-2020:2414. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
