CVE-2024-21545 (GCVE-0-2024-21545)

Vulnerability from cvelistv5 – Published: 2024-09-24 07:25 – Updated: 2024-09-24 14:57

Summary

Proxmox Virtual Environment is an open-source server management platform for enterprise virtualization. Insufficient safeguards against malicious API response values allow authenticated attackers with 'Sys.Audit' or 'VM.Monitor' privileges to download arbitrary host files via the API. When handling the result from a request handler before returning it to the user, the handle_api2_request function will check for the ‘download’ or ‘data’->’download’ objects inside the request handler call response object. If present, handle_api2_request will read a local file defined by this object and return it to the user. Two endpoints were identified which can control the object returned by a request handler sufficiently that the ’download’ object is defined and user controlled. This results in arbitrary file read. The privileges of this file read can result in full compromise of the system by various impacts such as disclosing sensitive files allowing for privileged session forgery.

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.
