pcs before version 0.9.164 and 0.10 is vulnerable to a privilege escalation via authorized user malicious REST call. The REST interface of the pcsd service did not properly sanitize the file name from the /remote/put_file query. If the /etc/booth directory exists, an authenticated attacker with write permissions could create or overwrite arbitrary files with arbitrary data outside of the /etc/booth directory, in the context of the pcsd process.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 8.7, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction . The vulnerability impacts integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 2 products from clusterlabs, from redhat organizations running these solutions should prioritize assessment and patching.
First disclosed in 2018, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques. Contemporary mitigation strategies focused on secure development practices and third-party component vetting.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For clusterlabs's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
