Title

Dolibarr < 24.0.0 Members REST API Sensitive Data Exposure via Member Endpoints

Summary

Dolibarr before 24.0.0 contains a sensitive data exposure vulnerability in the Members REST API that allows authenticated attackers with member-read rights to retrieve bcrypt password verifiers by querying member endpoints. Attackers can call the individual member or member list endpoints to obtain crypted password verifier fields that are not filtered by the base API serializer or the Members API class, potentially enabling offline password cracking attacks.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
