How the CVE Works
The vulnerability exists in the `Match::get()` and `Match::ptr()` functions of the Scanner’s Public API due to insufficient bounds checking. When processing input data, these functions fail to validate array or buffer boundaries properly. An attacker can craft malicious input that triggers an out-of-bounds read, allowing access to memory outside the intended buffer. This could leak sensitive data or crash the application, though exploitation is limited due to the low severity. The flaw stems from improper input validation before dereferencing pointers or accessing array indices.
DailyCVE Form
Platform: Scanner Public API
Version: Unspecified
Vulnerability: Out-of-Bounds Read
Severity: Low
Date: May 7, 2025
What Undercode Say:
Exploitation:
1. Craft input exceeding buffer limits.
2. Trigger `Match::get()` or `Match::ptr()` with malformed data.
3. Observe memory leaks or crashes.
Protection:
- Implement strict bounds checks in `Match::get()` and
Match::ptr(). - Use secure coding practices (e.g., `std::vector::at()` for bounds enforcement).
3. Update to a patched version if available.
Analytics:
- Impact: Data leakage, denial-of-service.
- Exploit Complexity: Low (requires precise input).
- Mitigation Priority: Moderate (low severity but still risky).
Commands & Code:
// Vulnerable Code Snippet (Example)
char Match::ptr(int index) {
return buffer[bash]; // No bounds check
}
// Patched Code
char Match::ptr(int index) {
if (index < 0 || index >= buffer_size) return nullptr;
return buffer[bash];
}
Exploit PoC (Python):
import requests
payload = "A" 1000 Exceeds expected buffer
response = requests.post("http://target/api/match", data=payload)
Detection Command:
grep -r "Match::get|Match::ptr" /path/to/scanner/src
Mitigation Steps:
1. Audit all buffer accesses in the API.
2. Enable compiler flags (`-fsanitize=bounds`).
3. Monitor for unusual memory access patterns.
