📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Local privilege escalation leading to full system compromise, data theft, or persistent backdoor installation

🟠

Likely Case

Application crash (denial of service) or limited code execution within application context

🟢

If Mitigated

No impact if proper access controls prevent local attacker access

🌐 Internet-Facing: LOW - Attack requires local access, not remotely exploitable
🏢 Internal Only: HIGH - Local attackers (including malicious insiders or compromised accounts) can exploit this vulnerability

🎯 Exploit Status

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

Exploit details are publicly available on GitHub. Attack requires local access to the system running the vulnerable software.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://www.sourcecodester.com/

Restart Required: No

Instructions:

1. Check vendor website for updates. 2. If patch available, download and install. 3. Replace main.c with patched version. 4. Recompile application if needed.

🔧 Temporary Workarounds

Remove vulnerable software

all

Uninstall Computer Store System 1.0 if not required

sudo apt remove computer-store-system
Or use system package manager

Restrict local access

linux

Limit who can access the system running vulnerable software

sudo chmod 700 /path/to/application
sudo chown root:root /path/to/application

🧯 If You Can't Patch

  • Implement strict access controls to prevent unauthorized local access
  • Monitor system for unusual process execution or crashes

🔍 How to Verify

Check if Vulnerable:

Check if Computer Store System 1.0 is installed: look for application files or check package manager

Check Version:

Check application documentation or version file if available

Verify Fix Applied:

Verify main.c file has been updated with proper buffer bounds checking

📡 Detection & Monitoring

Log Indicators:

  • Application crashes
  • Unusual process execution from application context
  • Stack overflow errors in system logs

Network Indicators:

  • None - local exploit only

SIEM Query:

Process:name="computer-store-system" AND (EventID:1000 OR "segmentation fault" OR "buffer overflow")
