AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A vulnerability in the management API of the affected product could allow an unauthenticated remote attacker to trigger service restarts. Successful exploitation could allow an attacker to disrupt services and negatively impact system availability.

CVE-2026-23596 is a vulnerability identified in the management API of Hewlett Packard Enterprise's Aruba Networking Private 5G Core, specifically version 1.24.3.0. The flaw allows an unauthenticated remote attacker to remotely trigger service restarts by exploiting the management API, which is exposed over the network. This leads to denial of service conditions by disrupting the availability of the Private 5G Core services. The vulnerability does not compromise confidentiality or integrity, as it does not allow data disclosure or modification, but it severely impacts availability by forcing service interruptions. The CVSS 3.1 base score is 6.5 (medium), with the vector indicating attack vector as adjacent network (AV:A), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impact limited to availability (A:H). No known exploits have been reported in the wild, suggesting limited active exploitation at present. The vulnerability was reserved in January 2026 and published in February 2026, indicating recent discovery. The affected product is used in private 5G network deployments, which are increasingly adopted by enterprises and critical infrastructure sectors for secure and dedicated wireless connectivity. The management API is a critical component for operational control, and its exposure to unauthenticated access represents a significant risk for service disruption. The lack of authentication requirements and ease of triggering service restarts make this vulnerability a concern for availability and operational continuity.
