Summary

ceph security update

Details

Ceph is a massively scalable, open-source, distributed storage system that runs on commodity hardware and delivers object, block and file system storage.

Security Fix(es):

Ceph is a distributed object, block, and file storage platform. In versions 17.2.7, 18.2.1 through 18.2.4, and 19.0.0 through 19.2.2, an unprivileged user can escalate to root privileges in a ceph-fuse mounted CephFS by chmod 777 a directory owned by root to gain access. The result of this is that a user could read, write and execute to any directory owned by root as long as they chmod 777 it. This impacts confidentiality, integrity, and availability. It is patched in versions 17.2.8, 18.2.5, and 19.2.3.(CVE-2025-52555)

Severity

6.5 (Medium)

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.
