How the CVE Works
CVE-2025-5297 is a critical stack-based buffer overflow vulnerability in SourceCodester Computer Store System 1.0, specifically in the `Add` function of main.c. The flaw occurs due to improper bounds checking when processing user-supplied input in the laptopcompany, RAM, and `Processor` arguments. An attacker can exploit this by providing excessively long input, overwriting the stack’s return address, and executing arbitrary code with the privileges of the application. Since the attack requires local access, exploitation may lead to privilege escalation or system compromise.

Vulnerability: Buffer Overflow
Severity: Critical
Date: 06/10/2025
Prediction: Patch by 07/15/2025
What Undercode Say:
Analytics:
- Exploitability Index: High (Local)
- Attack Vector: Local (AV:L)
- CVSS Score: 4.8 (Medium)
- Affected Component: `main.c`
Exploit Commands:
Crash PoC (Python) import subprocess payload = "A" 1024 subprocess.call(["./compstore", "--laptopcompany", payload, "--RAM", payload, "--Processor", payload])
Mitigation Steps:
1. Input Validation:
if (strlen(laptopcompany) > 64 || strlen(RAM) > 16 || strlen(Processor) > 32) {
exit(1);
}
2. Compiler Protections:
gcc -fstack-protector-strong -D_FORTIFY_SOURCE=2 -O2 main.c -o compstore
3. Workaround: Restrict local user access until patched.
Detection (Linux):
Check vulnerable processes ps aux | grep compstore
Log Analysis:
grep -i "segmentation fault" /var/log/syslog
Patch Verification:
strings compstore | grep "stack_chk_fail"
