CVE-2005-0116
Improper Input Validation in AWStats 6
Executive Summary
CVE-2005-0116 is a unknown severity vulnerability affecting appsec. It is classified as CWE-20. Ensure your systems and dependencies are patched immediately to mitigate exposure risks.
Precogs AI Insight
"AWStats contains an OS command injection vulnerability in the `awstats.pl` script. Unauthenticated attackers inject shell commands via the `configdir` parameter when the `AllowToUpdateStatsFromBrowser` feature is enabled. Precogs API Security Engine tracks untrusted input flows to system shell execution."
What is this vulnerability?
CVE-2005-0116 is categorized as a unknown Improper Input Validation flaw. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.
AWStats 6.1, and other versions before 6.3, allows remote attackers to execute arbitrary commands via shell metacharacters in the configdir parameter to aswtats.pl.
This architectural defect enables adversaries to bypass intended security controls, directly manipulating the application's execution state or data layer. Immediate strategic intervention is required.

Impact on Systems
✅ Data Exfiltration: Attackers can extract sensitive data from backend databases, configuration files, or internal services.
✅ Authentication Bypass: Exploiting this flaw may allow unauthorized access to protected resources and administrative interfaces.
✅ Lateral Movement: Once initial access is gained, attackers can pivot to internal systems and escalate privileges.
How to Fix and Mitigate CVE-2005-0116
- Apply Vendor Patches: Upgrade affected components to their latest, non-vulnerable versions immediately.
- Implement Input Validation: Ensure all user-supplied data is validated, sanitized, and type-checked before processing.
- Deploy Runtime Protection: Use Precogs continuous monitoring to detect exploitation attempts in real time.
- Audit Dependencies: Review and update all third-party libraries and transitive dependencies.

Vulnerability Code Signature
Attack Data Flow
| Stage | Detail |
|---|---|
| Source | Untrusted User Input |
| Vector | Input flows through the application logic without sanitization |
| Sink | Execution or Rendering Sink |
| Impact | Application compromise, Logic Bypass, Data Exfiltration |
Vulnerable Code Pattern
# ❌ VULNERABLE: Unsanitized Input Flow
def process_request(request):
user_input = request.GET.get('data')
# Taint sink: processing untrusted data
execute_logic(user_input)
return {"status": "success"}
Secure Code Pattern
# ✅ SECURE: Input Validation & Sanitization
def process_request(request):
user_input = request.GET.get('data')
# Sanitized boundary check
if not is_valid_format(user_input):
raise ValueError("Invalid input format")
sanitized_data = sanitize(user_input)
execute_logic(sanitized_data)
return {"status": "success"}
