CVE-2026-24828

7.5 HIGH

📋 TL;DR

This is a memory leak vulnerability (CWE-401) in Is-Daouda is-Engine software where memory is not properly released after use. This allows attackers to cause denial of service through resource exhaustion. All users of is-Engine before version 3.3.4 are affected.

💻 Affected Systems

Products:
  • Is-Daouda is-Engine
Versions: All versions before 3.3.4
Operating Systems: All platforms running is-Engine
Default Config Vulnerable: ⚠️ Yes
Notes: Any system using is-Engine as a component or framework is vulnerable regardless of configuration.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system unavailability due to memory exhaustion leading to denial of service, potentially affecting all services using the vulnerable component.

🟠

Likely Case

Degraded performance and intermittent service disruptions as memory consumption grows over time, eventually requiring system restart.

🟢

If Mitigated

Minimal impact with proper monitoring and resource limits in place, though memory consumption may still be higher than normal.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Memory leak vulnerabilities typically require repeated requests to trigger, but exploitation is straightforward once identified.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 3.3.4

Vendor Advisory: https://github.com/Is-Daouda/is-Engine/pull/6

Restart Required: Yes

Instructions:

1. Backup current configuration and data. 2. Stop all services using is-Engine. 3. Update to version 3.3.4 or later. 4. Restart services. 5. Verify functionality.

🔧 Temporary Workarounds

Memory limit enforcement

linux

Set memory limits on processes using is-Engine to prevent complete system exhaustion

ulimit -v [memory_limit_in_kb]
docker run --memory=[limit]

Regular service restart

linux

Schedule periodic restarts of services using is-Engine to clear accumulated memory

systemctl restart [service_name]

🧯 If You Can't Patch

  • Implement aggressive memory monitoring and alerting for processes using is-Engine
  • Deploy behind rate-limiting proxies to reduce request frequency

🔍 How to Verify

Check if Vulnerable:

Check is-Engine version with: is-engine --version or examine package manager output

Check Version:

is-engine --version

Verify Fix Applied:

Confirm version is 3.3.4 or higher and monitor memory usage over time for stability

📡 Detection & Monitoring

Log Indicators:

  • Increasing memory usage patterns
  • Out of memory errors
  • Frequent garbage collection

Network Indicators:

  • Unusually high request rates to is-Engine endpoints
  • Service degradation over time

SIEM Query:

source="system_logs" AND ("out of memory" OR "memory allocation failed") AND process="is-engine"
