CVE-2018-14649 (GCVE-0-2018-14649)

Vulnerability from cvelistv5 – Published: 2018-10-09 17:00 – Updated: 2024-08-05 09:38

Summary

It was found that ceph-isci-cli package as shipped by Red Hat Ceph Storage 2 and 3 is using python-werkzeug in debug shell mode. This is done by setting debug=True in file /usr/bin/rbd-target-api provided by ceph-isci-cli package. This allows unauthenticated attackers to access this debug shell and escalate privileges. Once an attacker has successfully connected to this debug shell they will be able to execute arbitrary commands remotely. These commands will run with the same privileges as of user executing the application which is using python-werkzeug with debug shell mode enabled. In - Red Hat Ceph Storage 2 and 3, ceph-isci-cli package runs python-werkzeug library with root level permissions.

Once an attacker has successfully connected to this debug shell they will be able to execute arbitrary commands remotely. These commands will run with the same privileges as of user executing the application which is using python-werkzeug with debug shell mode enabled. In - Red Hat Ceph Storage 2 and 3, ceph-isci-cli package runs python-werkzeug library with root level permissions."

Detection rules are retrieved from Rulezet.

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.
