CVE-2026-24831: ixray-1.6-stcop Infinite Loop DoS Flaw

CVE-2026-24831 Overview

CVE-2026-24831 is a Loop with Unreachable Exit Condition (Infinite Loop) vulnerability (CWE-835) affecting ixray-team's ixray-1.6-stcop project. This denial of service vulnerability allows remote attackers to trigger an infinite loop condition, causing the affected application to become unresponsive and consume system resources indefinitely.

Critical Impact

Remote attackers can exploit this vulnerability to cause a denial of service condition by triggering an infinite loop, rendering the ixray-1.6-stcop application unavailable and potentially exhausting system resources.

Affected Products

• ixray-1.6-stcop versions prior to 1.3

Technical Details for CVE-2026-24831

Vulnerability Analysis

This vulnerability is classified as CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop'). The flaw exists in ixray-1.6-stcop where certain code paths contain loops with exit conditions that cannot be satisfied under specific circumstances. When an attacker provides crafted input or triggers specific application states, the loop continues indefinitely, preventing the application from processing other requests and consuming CPU resources.

The vulnerability is exploitable over the network without requiring authentication or user interaction. While this flaw does not compromise data confidentiality or integrity, it poses a significant availability risk as it can completely halt normal application operations.

Root Cause

The root cause stems from improper loop termination logic within the ixray-1.6-stcop codebase. The loop's exit condition relies on state or data that, under certain circumstances, never reaches the expected termination value. This programming error allows the execution flow to become trapped in an endless iteration cycle.

Attack Vector

The vulnerability can be exploited remotely over the network. An attacker can send specially crafted requests or data to the vulnerable ixray-1.6-stcop instance to trigger the infinite loop condition. Since no privileges or user interaction are required, this attack can be launched anonymously against any exposed instance.

The technical details of the vulnerability and its fix are documented in the GitHub Pull Request for ixray.

Detection Methods for CVE-2026-24831

Indicators of Compromise

• Abnormally high CPU utilization by ixray-1.6-stcop processes that persists indefinitely
• Application unresponsiveness or failure to process new requests
• System logs indicating process hangs or timeout errors related to ixray components
• Memory consumption patterns showing consistent resource usage without processing completion

Detection Strategies

• Monitor CPU usage metrics for ixray-1.6-stcop processes and alert on sustained high utilization
• Implement application-level health checks to detect unresponsive states
• Configure network monitoring to identify unusual request patterns that may indicate exploitation attempts
• Enable process monitoring to detect threads stuck in infinite execution loops

Monitoring Recommendations

• Set up automated alerts for CPU threshold violations specific to ixray processes
• Implement request timeout monitoring to identify hung operations
• Deploy application performance monitoring (APM) solutions to track request completion rates
• Create dashboards to visualize ixray-1.6-stcop service availability and responsiveness metrics

How to Mitigate CVE-2026-24831

Immediate Actions Required

• Update ixray-1.6-stcop to version 1.3 or later immediately
• Review system logs for any evidence of prior exploitation attempts
• Implement network-level rate limiting to reduce the impact of potential DoS attempts
• Consider temporarily restricting network access to affected instances until patching is complete

Patch Information

The ixray-team has addressed this vulnerability in version 1.3 of ixray-1.6-stcop. The fix corrects the loop termination logic to ensure proper exit conditions are always reachable. Details of the patch implementation can be reviewed in the GitHub Pull Request #248.

Organizations should prioritize upgrading to the patched version as the primary remediation strategy.

Workarounds

• Deploy network-level controls such as rate limiting and connection throttling to reduce exploitation impact
• Implement process monitoring with automatic restart capabilities to recover from hung states
• Use load balancers with health checks to route traffic away from unresponsive instances
• Consider running instances in containers with resource limits to prevent system-wide resource exhaustion
