CVE-2025-4891
📋 TL;DR
A critical buffer overflow vulnerability exists in the Police Station Management System 1.0, specifically in the criminal record display function. Attackers can exploit this by manipulating input to cause memory corruption, potentially leading to arbitrary code execution. This affects all users running the vulnerable version of this software.
💻 Affected Systems
- Police Station Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Local privilege escalation leading to complete system compromise, data theft, or persistent backdoor installation.
Likely Case
Application crash (denial of service) or limited code execution within the application context.
If Mitigated
Application crash without code execution if memory protections like ASLR/DEP are effective.
🎯 Exploit Status
Exploit has been publicly disclosed and manipulation of the 'N' argument leads directly to buffer overflow.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider the workarounds below or discontinue use of the software.
🔧 Temporary Workarounds
Input Validation Enhancement
allAdd bounds checking for the 'N' parameter in the criminal::display function to prevent buffer overflow.
// In source.cpp, modify criminal::display function to validate input size before processing
Compile with Security Flags
linuxRecompile the application with stack protection and other security compiler flags.
gcc -fstack-protector-all -D_FORTIFY_SOURCE=2 -O2 source.cpp -o police_system
🧯 If You Can't Patch
- Isolate the application in a restricted environment with minimal privileges
- Implement network segmentation to limit access to the system
🔍 How to Verify
Check if Vulnerable:
Check if Police Station Management System version 1.0 is installed and review source.cpp for vulnerable criminal::display function.Check Version:
Check application documentation or about dialog for version informationVerify Fix Applied:
Test with boundary values for the 'N' parameter to ensure no buffer overflow occurs.📡 Detection & Monitoring
