CVE-2026-103057 in AiSOC
Summary
by MITRE • 09/30/2026
AiSOC versions 5.1.0 before 12.0.0 contain an authentication bypass vulnerability in the realtime service internal endpoints POST /internal/agent-event and POST /internal/push. Attackers can post arbitrary events with spoofed tenant identifiers to broadcast malicious content over WebSocket and Redis SSE channels or send unauthorized notifications to registered devices.

AiSOC versions 5.1.0 through 12.0.0 contain a critical authentication bypass vulnerability affecting the internal endpoints of its realtime service, specifically POST /internal/agent-event and POST /internal/push. This flaw stems from an insufficient validation mechanism that fails to enforce strict access controls on these administrative interfaces. Because these endpoints are designed for internal communication between system components rather than direct user interaction, they were likely intended to be protected by network-level isolation or implicit trust assumptions within the application architecture. However, the absence of explicit authentication checks allows any actor with network reachability to interact directly with these services, effectively bypassing the standard security perimeter established by the main web interface.
The technical nature of this vulnerability involves the ability for an attacker to inject arbitrary events into the system while spoofing tenant identifiers. By manipulating the request payload, a malicious user can impersonate legitimate agents or administrative processes. This capability is particularly dangerous because it allows the injection of false data that appears authentic to downstream consumers within the AiSOC ecosystem. The exploitation does not require valid credentials for the main application but rather relies on network access and the ability to craft specific HTTP POST requests targeting these internal API routes.
The operational impact of this vulnerability is severe, as it enables two primary attack vectors involving real-time data channels. First, attackers can broadcast malicious content over WebSocket connections and Redis Server-Sent Events (SSE) channels. These technologies are typically used for low-latency communication in security information and event management systems to push alerts or updates to connected clients. By injecting forged events, an attacker could flood the system with false positives, trigger unnecessary automated responses, or obscure genuine threats by creating noise that overwhelms analysts. Second, the vulnerability allows for the sending of unauthorized notifications directly to registered devices. This means attackers can manipulate device behavior, potentially causing denial-of-service conditions on endpoints or tricking users into taking actions based on fabricated alerts generated within the platform.
From a classification perspective, this issue aligns with CWE-287 Improper Authentication and CWE-306 Missing Authentication for Critical Function. The failure to require authentication for internal administrative functions represents a fundamental breach of security principles where trust is assumed without verification. In terms of offensive cybersecurity frameworks such as MITRE ATT&CK, this vulnerability facilitates techniques related to Command and Control via Application Layer Protocol, specifically leveraging WebSocket or SSE channels for data exfiltration or command execution if the injected events are interpreted by downstream services. It also relates to Impactful actions like Data Manipulation and Service Availability disruption through false alert generation.
Mitigation strategies must prioritize immediate remediation of this access control gap. The most effective solution is to upgrade AiSOC to version 12.0.0 or later, where the vendor has addressed these authentication deficiencies in the realtime service endpoints. For environments unable to patch immediately due to operational constraints, network-level isolation should be enforced. This involves configuring firewalls or security groups to restrict access to ports associated with the internal agent-event and push services exclusively to trusted application servers and management nodes. Additionally, implementing mutual TLS (mTLS) for inter-service communication can provide an additional layer of verification that ensures only authorized components can interact with these sensitive endpoints. Continuous monitoring of WebSocket and SSE traffic patterns should also be implemented to detect anomalies indicative of spoofed tenant identifiers or unusual event volumes.
