Q: Who is affected? (Versions/Components)

🎯 **Affected**: **Chatwoot** versions **prior to 3.16.0**. 📦 **Component**: The core chat support application, specifically the filter query handling mechanism.

Q: Is exploitation threshold high? (Auth/Config)

⚠️ **Threshold**: **Low** for Authenticated Users. 📝 **Auth Required**: Yes, **PR:L** (Low Privileges) is needed. 🌐 **Network**: **AV:N** (Network Accessible). No user interaction (**UI:N**) required once authenticated.

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **HIGH**. 📅 **Published**: Jan 9, 2025. 🚨 **Reason**: CVSS Vector shows **High** Confidentiality impact and **Low** complexity. Public PoC is available. Immediate patching to v3.16.0+ is critical.

Question 1

What is this vulnerability? (Essence + Consequences)

Accepted Answer

🚨 **Essence**: Chatwoot < 3.16.0 suffers from **SQL Injection (SQLi)**. 📉 **Consequences**: Attackers inject malicious SQL via filters, bypassing input sanitization. This compromises data integrity and confidentiality.

Question 2

Root Cause? (CWE/Flaw)

Accepted Answer

🛡️ **Root Cause**: **CWE-89** (Improper Neutralization of Special Elements used in an SQL Command).…

Question 3

Who is affected? (Versions/Components)

Accepted Answer

🎯 **Affected**: **Chatwoot** versions **prior to 3.16.0**. 📦 **Component**: The core chat support application, specifically the filter query handling mechanism.

Question 4

What can hackers do? (Privileges/Data)

Accepted Answer

💀 **Hackers' Power**: Execute **arbitrary SQL** commands. 📂 **Impact**: High risk of **Data Exfiltration** (Confidentiality), potential **Data Modification** (Integrity), and service disruption (Availability).…

Question 5

Is exploitation threshold high? (Auth/Config)

Accepted Answer

⚠️ **Threshold**: **Low** for Authenticated Users. 📝 **Auth Required**: Yes, **PR:L** (Low Privileges) is needed. 🌐 **Network**: **AV:N** (Network Accessible). No user interaction (**UI:N**) required once authenticated.

Question 6

Is there a public Exp? (PoC/Wild Exploitation)

Accepted Answer

🔓 **Exploit Status**: **Yes**, Public PoC exists. 📂 **Source**: GitHub repository `elahehasanpour/chatwoot-cve-2025-21628` provides a technical write-up and likely proof-of-concept code.…

Question 7

How to self-check? (Features/Scanning)

Accepted Answer

🔍 **Self-Check**: Scan for Chatwoot instances running version **< 3.16.0**. 🧪 **Test**: If authenticated, attempt to manipulate filter parameters to inject duplicate **WHERE** clauses.…

Question 8

Is it fixed officially? (Patch/Mitigation)

Accepted Answer

✅ **Official Fix**: **Yes**. 🛠️ **Patch**: Upgrade to **Chatwoot 3.16.0** or later. 🔗 **Reference**: Commit `b34dac7bbe3c910186083b680e51aad5ea60b44b` addresses the issue.…

Question 9

What if no patch? (Workaround)

Accepted Answer

🚧 **No Patch?**: Implement strict **Input Validation** on filter parameters. 🚫 **Mitigation**: Restrict database user privileges to minimize SQLi impact.…

Question 10

Is it urgent? (Priority Suggestion)
