AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A denial of service vulnerability (CVE-2024-53580) exists in iperf3 due to improper JSON handling. Iperf3 is a network testing tool used to measure TCP bandwidth and tune UDP characteristics. This vulnerability affects Red Hat Enterprise Linux 7 Extended Lifecycle Support versions. Red Hat has issued a security advisory with an update to address this issue.

CVE-2024-53580 is a denial of service vulnerability in iperf3 caused by improper handling of JSON input. Iperf3 is a tool that measures maximum TCP bandwidth and UDP characteristics such as delay jitter and datagram loss. The vulnerability could allow an attacker to cause a denial of service condition by exploiting the improper JSON processing. Red Hat has released an update for iperf3 in Red Hat Enterprise Linux 7 Extended Lifecycle Support to fix this issue as detailed in advisory RHSA-2025:0402.

Red Hat Security Advisory: iperf3 security update

iperf

iperf v3.17.1 was discovered to contain a segmentation violation via the iperf_exchange_parameters() function.

CVE-2024-53580 identifies a vulnerability in iperf version 3.17.1, specifically within the iperf_exchange_parameters() function. iperf is a widely used open-source tool for measuring network bandwidth and performance. The vulnerability manifests as a segmentation violation, which is typically caused by dereferencing a null or invalid pointer, classified under CWE-476 (NULL Pointer Dereference). This flaw can be triggered remotely without requiring any authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). Exploiting this vulnerability leads to a crash of the iperf process, resulting in a denial of service (DoS) condition. The CVSS score of 7.5 reflects a high severity due to the ease of exploitation and the impact on availability, although confidentiality and integrity remain unaffected. No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. Organizations relying on iperf for network diagnostics and performance testing should be aware that this vulnerability could disrupt their network monitoring capabilities if exploited.
