Published: 12 October 2022
Summary
CVE-2022-40871 is a critical-severity Code Injection (CWE-94) vulnerability in Dolibarr Dolibarr Erp\/Crm. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 2.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Dolibarr ERP & CRM versions through 15.0.3 contain an eval injection vulnerability tracked as CVE-2022-40871 and CWE-94. The flaw resides in the application's handling of database content that is later passed to PHP eval, enabling arbitrary code execution. The issue carries a CVSS 3.1 score of 9.8 with network attack vector and no required authentication or user interaction.
An unauthenticated attacker can first add an administrative account via the publicly accessible installation page, which is enabled by default. Once present, the attacker can store malicious PHP code in the database; subsequent processing of that data by eval results in remote code execution with the full privileges of the Dolibarr process, allowing complete system compromise.
Public exploit code demonstrating the attack chain is available on GitHub. The CVE maintains an EPSS score of 0.5156, indicating substantial observed exploitation interest.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
