Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: B1GBB `footer.inc.php` has a **Remote File Inclusion (RFI)** flaw. π **Consequences**: Attackers inject malicious URLs via the `tfooter` parameter to execute **arbitrary PHP code** on the server.β¦
π‘οΈ **Root Cause**: **PHP Remote File Inclusion**. The code fails to validate the `tfooter` parameter. π« It allows external URLs to be included and executed as local scripts. β οΈ Classic input validation failure.
Q3Who is affected? (Versions/Components)
π― **Affected**: **B1GBB** (specifically the `footer.inc.php` component). π **Published**: June 26, 2007. π¦ **Vendor**: n/a (Community/Forum software). Check if you are running legacy B1GBB versions.
Q4What can hackers do? (Privileges/Data)
π **Attacker Power**: Execute **Arbitrary PHP Code**. π This means full server control! π Access sensitive data, install backdoors, or deface the site. π Privileges escalate to the web server user.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **LOW**. πͺ **Auth**: None required (Remote). βοΈ **Config**: Exploitable via URL parameter `tfooter`. π― Easy to trigger with a simple HTTP request. No login needed!
Q6Is there a public Exp? (PoC/Wild Exploitation)
π’ **Public Exp?**: Yes. π References exist from **SecurityFocus (BID 24624)**, **X-Force**, and **Vupen**. π§ͺ Proof-of-Concepts and advisories are widely available online. Wild exploitation is likely.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for `footer.inc.php` endpoints. π§ͺ Test the `tfooter` parameter with a malicious URL payload. π‘ Look for HTTP 200 OK responses indicating successful inclusion. Use automated RFI scanners.
Q8Is it fixed officially? (Patch/Mitigation)
π οΈ **Official Fix**: Data shows **no specific patch** listed. π Old vulnerability (2007). β³ Likely deprecated software. Check vendor archives or legacy support channels for updates.
Q9What if no patch? (Workaround)
π§ **No Patch?**: **Mitigation**: Block external URL inclusion in `php.ini` (`allow_url_include = Off`). π« Sanitize the `tfooter` input strictly. 𧱠Use a WAF to block RFI patterns. Isolate the server!
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH** (if still in use). π Though old, RFI is critical. π If you run B1GBB, patch immediately or decommission. π Do not ignore legacy RFI flaws!
