CVE-2026-24832

9.8 CRITICAL

📋 TL;DR

CVE-2026-24832 is an out-of-bounds write vulnerability in ixray-team's ixray-1.6-stcop software that allows attackers to write data beyond allocated memory boundaries. This can lead to arbitrary code execution, denial of service, or memory corruption. All users running affected versions of ixray-1.6-stcop are vulnerable.

💻 Affected Systems

Products:
  • ixray-team ixray-1.6-stcop
Versions: All versions before 1.3
Operating Systems: All operating systems running ixray-1.6-stcop
Default Config Vulnerable: ⚠️ Yes
Notes: All deployments of affected versions are vulnerable regardless of configuration.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution with SYSTEM/root privileges leading to complete system compromise, data exfiltration, and persistent backdoor installation.

🟠

Likely Case

Application crash leading to denial of service, potential information disclosure through memory leaks, or limited code execution in application context.

🟢

If Mitigated

Application crash with no data loss if proper segmentation and privilege separation are implemented.

🌐 Internet-Facing: HIGH - The vulnerability can be exploited remotely without authentication, making internet-facing instances immediate targets.
🏢 Internal Only: HIGH - Even internal instances are vulnerable to insider threats or lateral movement from compromised systems.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Out-of-bounds write vulnerabilities typically have low exploitation complexity, especially with CVSS 9.8 rating suggesting trivial exploitation.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.3 or later

Vendor Advisory: https://github.com/ixray-team/ixray-1.6-stcop/pull/257

Restart Required: Yes

Instructions:

1. Download version 1.3 or later from official repository. 2. Stop the ixray-1.6-stcop service. 3. Replace the binary with patched version. 4. Restart the service. 5. Verify successful update.

🔧 Temporary Workarounds

Network Segmentation

linux

Restrict network access to ixray-1.6-stcop instances using firewall rules

iptables -A INPUT -p tcp --dport [ixray-port] -s [trusted-networks] -j ACCEPT
iptables -A INPUT -p tcp --dport [ixray-port] -j DROP

Process Isolation

linux

Run ixray-1.6-stcop in container or with reduced privileges

docker run --cap-drop=ALL --security-opt=no-new-privileges ixray-team/ixray-1.6-stcop:latest

🧯 If You Can't Patch

  • Disable or remove ixray-1.6-stcop from production systems immediately
  • Implement strict network access controls and monitor for exploitation attempts

🔍 How to Verify

Check if Vulnerable:

Check current version: ./ixray-1.6-stcop --version or examine binary metadata. If version is below 1.3, system is vulnerable.

Check Version:

./ixray-1.6-stcop --version | grep -i version

Verify Fix Applied:

Verify version is 1.3 or higher and test basic functionality. Monitor logs for any crash or abnormal behavior.

📡 Detection & Monitoring

Log Indicators:

  • Segmentation fault errors
  • Memory access violation logs
  • Unexpected process termination
  • Abnormal memory usage patterns

Network Indicators:

  • Unusual traffic to ixray-1.6-stcop port
  • Exploit kit signatures
  • Shellcode patterns in network traffic

SIEM Query:

source="ixray.log" AND ("segmentation fault" OR "access violation" OR "SIGSEGV")
