How the CVE Works:
CVE-2025-3166 is a stack-based buffer overflow vulnerability in Product Management System 1.0, specifically in the `search_item` function of the Search Product Menu. The flaw occurs when an overly long `target` argument is passed, exceeding the allocated buffer size and corrupting adjacent stack memory. Attackers with local access can exploit this to execute arbitrary code, escalate privileges, or crash the application. The vulnerability stems from improper bounds checking before copying user-supplied data into a fixed-size buffer.

What Undercode Say:
Exploitation:
1. Crash Trigger:
./pms_search --target $(python -c 'print("A" 1024)')
2. Shellcode Injection (x64):
payload = b"\x90" 200 + shellcode + b"A" (1024 - 200 - len(shellcode))
3. EIP Control (x86):
payload = b"A" offset + pack("<I", 0xdeadbeef)
Protection:
1. Patch: Apply vendor updates.
2. Compilation Flags:
gcc -fstack-protector-strong -D_FORTIFY_SOURCE=2 -O2
3. Runtime Mitigations:
echo 1 > /proc/sys/kernel/randomize_va_space ASLR
4. Input Validation:
if (strlen(target) >= MAX_LEN) exit(1);
Forensics:
1. Log Analysis:
grep "pms_search" /var/log/auth.log
2. Core Dump Inspection:
gdb /usr/bin/pms_search core --batch -ex "info registers"
Detection:
1. YARA Rule:
rule pms_overflow {
strings: $s = "search_item"
condition: $s and filesize < 1MB
}
2. Network Monitoring:
tcpdump -i eth0 'dst port 80 and payload matches "AAAAAAAA"'
