Details

** exclusively-hosted-service ** A Stored Cross-Site Scripting (XSS) vulnerability in the chat functionality of the SelfBest platform 2023.3 allows authenticated low-privileged attackers to execute arbitrary JavaScript in the context of other users' sessions. This can be exploited to access administrative data and functions, leading to privilege escalation and full compromise of sensitive user data, as demonstrated by the ability to fetch and exfiltrate the contents of the /admin/users endpoint.

Severity

9.1 (Critical)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

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.
