Please contact JTAC for technical support for further guidance. An indicator of compromise may be to monitor NETISR drops in the network with the assistance of JTAC. Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. This attack occurs when the attackers' packets are sent over an IPv4 unicast routing equal-cost multi-path (ECMP) unilist selection. During an attack, the routing protocol daemon (rpd) CPU may reach 100% utilization, yet FPC CPUs forwarding traffic will operate normally.

Nextcloud Server versions 23.0.10 and 24.0.6 and Nextcloud Enterprise Server versions 22.2.10, 23.0.10, and 24.0.6 contain patches for this issue. Nextcloud Server prior to versions 23.0.10 and 24.0.6 and Nextcloud Enterprise Server prior to versions 22.2.10, 23.0.10, and 24.0.6 are vulnerable to a logged-in attacker slowing down the system by generating a lot of database/cpu load. Nextcloud Server is the file server software for Nextcloud, a self-hosted productivity platform. During an attack, an authoritative server must return large NS sets or address sets. Knot Resolver before 5.5.3 allows remote attackers to cause a denial of service (CPU consumption) because of algorithmic complexity. For example, the attack payload could be placed in the Location header of an HTTP response with status code 302. Hostnames are often supplied by remote servers that could be controlled by a malicious actor in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname. An unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name being presented to the decoder could lead to a CPU denial of service. An issue was discovered in Python before 3.11.1.
