Blind SQL Injection in Dolibarr WhatsApp Module

Publication date: 2026-11-12

Last updated on: 2026-11-12

Assigner: Spanish National Cybersecurity Institute, S.A. (INCIBE)

Description
Blind SQL injection vulnerability in the public endpoint `public/webhook/receiver.php` of the WhatsApp module for Dolibarr 1.9. The phone number value derived from the `data.key.remoteJid` parameter, received via a JSON request, is incorporated into an SQL query without escaping or parameterization. With the WHATSAPP_WEBHOOK_ALLOW option enabled, an unauthenticated remote attacker could manipulate this parameter to alter the query. Exploitation using a timing-based technique could allow an attacker to extract information from the database and cause service disruption.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This is a blind SQL injection vulnerability in the WhatsApp module for Dolibarr version 1.9. It exists in the public endpoint public/webhook/receiver.php where the phone number value from the data.key.remoteJid parameter in a JSON request is directly used in an SQL query without proper escaping or parameterization. An unauthenticated remote attacker can exploit this by manipulating the parameter to alter the query and extract database information or disrupt services if the WHATSAPP_WEBHOOK_ALLOW option is enabled.

The vulnerability has a CVSS v4.0 base score of 8.8, indicating high severity due to its potential impact on confidentiality and availability.

Detection Guidance

To detect this vulnerability, monitor network traffic for requests to the vulnerable endpoint public/webhook/receiver.php. Check for JSON payloads containing the data.key.remoteJid parameter. Use tools like curl to test the endpoint with crafted inputs that may trigger delayed responses, indicating potential SQL injection. Example command: curl -X POST -H 'Content-Type: application/json' -d '{"data":{"key":{"remoteJid":"test'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"'"' OR SLEEP(5)--"}}' http://target.com/public/webhook/receiver.php

Inspect server logs for unusual queries or timing delays in responses from the webhook endpoint. Enable database query logging to identify suspicious patterns.

Impact Analysis

An attacker could exploit this to extract sensitive data from the database such as user credentials, personal information, or other confidential data. They could also cause service disruption by altering queries or deleting data. The attack requires no authentication and can be performed remotely if the vulnerable option is enabled.

Compliance Impact

This vulnerability could lead to unauthorized access and exfiltration of personal data, which would violate GDPR and HIPAA requirements for protecting sensitive information. Organizations using the affected module may face compliance violations, legal penalties, and reputational damage if exploited.

Mitigation Strategies

Immediately update the WhatsApp for Dolibarr module to the patched version provided by the vendor. If an update is not available, disable the WHATSAPP_WEBHOOK_ALLOW option in the module configuration to prevent exploitation.

Restrict access to the public/webhook/receiver.php endpoint by implementing IP whitelisting or firewall rules. Monitor the endpoint for any signs of exploitation attempts.
