---- Arrowchat V1 8 3 Nulled 13 Now

| Action | Priority | Rationale | |--------|----------|-----------| | Do not install the nulled build | Critical | Eliminates legal and security exposure. | | Purchase a current, supported ArrowChat license | High | Receives security patches, official support, and compliance. | | If real‑time chat is required and budget is limited: • Evaluate open‑source alternatives (e.g., Rocket.Chat, Mattermost, LiveHelperChat). | High | Free, actively maintained, no licensing risk. | | If the nulled version is already deployed: • Immediately isolate the server (disable public access). • Scan for malicious files (look for eval(base64_decode, gzinflate, hidden *.php in uploads/). • Replace the codebase with a clean, licensed version. • Rotate all credentials (DB passwords, API keys, admin passwords). | Critical | Limits potential compromise and data loss. | | Perform a full security audit (web‑app scanner, code review) | Medium | Detect any residual back‑doors or vulnerable endpoints. | | Implement Web Application Firewall (WAF) | Medium | Blocks known injection patterns targeting ArrowChat endpoints. | | Enable HTTPS, secure cookies, and SameSite attributes | Medium | Reduces session‑hijacking risk. | | Log and monitor – Access logs for /ajax/* – Database query anomalies | Medium | Early detection of exploitation attempts. |

| CVE / Advisory | Issue | Impact | Mitigation (official) | |----------------|-------|--------|-----------------------| | CVE‑2016‑XXXX | Unvalidated input in chat.php → SQL Injection | Remote code execution, data exfiltration | Parameterized queries (patch released in v2.0) | | CVE‑2017‑YYYY | Improper file inclusion in loader.php | Arbitrary file read/write | Harden file path handling | | CVE‑2018‑ZZZZ | CSRF on admin/settings.php | Privilege escalation for logged‑in admins | Enforce same‑origin token | | Advisory 2019‑01 | Insecure session handling (session fixation) | Session hijacking | Regenerate session ID after login | ---- Arrowchat V1 8 3 Nulled 13

Note: None of these were patched in the 1.8.3 branch. | CVE / Advisory | Issue | Impact

| Risk | Description | Likelihood | |------|-------------|------------| | Hidden back‑door | Malicious code may create an undocumented admin account or remote shell (eval(base64_decode(...)))). | High (observed in many community‑released nulled packs) | | Malware dropper | The package can include a separate PHP file that downloads ransomware or crypto‑miner payloads. | Medium‑High | | Obfuscated code | Use of gzinflate, str_rot13, or preg_replace with the /e/ modifier makes static analysis difficult. | High | | License bypass | License check removal does not guarantee functional stability; missing files may cause runtime errors. | Medium | | No support / updates | New vulnerabilities discovered after 2017 will remain exploitable. | Certain | LiveHelperChat ). | High | Free
