Overview
The cybersecurity landscape is constantly evolving, with threats becoming increasingly sophisticated. Among these threats, remote code execution (RCE) vulnerabilities pose a particularly high risk. This post delves into one such vulnerability, designated as CVE-2025-56588, affecting Dolibarr ERP & CRM v21.0.1. This vulnerability was discovered in the User module configuration via the computed field parameter, and potentially allows an attacker to execute arbitrary code remotely. This can lead to system compromise or data leakage, highlighting the critical importance of understanding and mitigating this vulnerability.

Dolibarr ERP & CRM | v21.0.1
How the Exploit Works
This vulnerability originates from an insecure handling of user inputs in the User module configuration within Dolibarr ERP & CRM v21.0.1. By manipulating the computed field parameter, an attacker can inject malicious code, which is then executed within the context of the application. This allows the attacker to perform actions as if they were the application itself, potentially leading to a complete system compromise or data leakage.
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited. The attacker crafts a malicious payload and inserts it into the computed field parameter in an HTTP request to the vulnerable endpoint.
POST /user/module/configuration HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "computed_field": "malicious_code_here" }In this example, `malicious_code_here` represents the attacker’s crafted code, which will be executed when processed by the server.
It’s important to note that this is a simplified representation. In reality, exploiting this vulnerability would likely require a more complex payload and a thorough understanding of the application’s internals.
Mitigation
The best course of action to mitigate this vulnerability is to apply the patch provided by the vendor. If this is not immediately feasible, you can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary measure. These tools can detect and block attempts to exploit this vulnerability, minimizing potential damage.
In the long-term, organizations should prioritize keeping their software up-to-date and regularly scanning for vulnerabilities to ensure their systems remain secure.
