CVE-2026-8326: CWE-23 Relative path traversal in Remote Spark (https://www.remotespark.com/) SparkView
Path traversal vulnerability in Remote Spark (https://www.Remotespark.Com/) SparkView allows reading and writing arbitrary files in all directories as root. This leads to RCE. The affected component is the RDP drive redirection. Depending on implementation, the vulnerability can be exploited by an unauthenticated attacker. This issue affects SparkView: before build 1127.
AI Analysis
Technical Summary
This vulnerability (CWE-23) in Remote Spark's SparkView component involves relative path traversal through the RDP drive redirection feature. It enables an attacker without authentication to access and modify files across the system with root privileges, resulting in remote code execution. The issue affects versions prior to build 1127. The CVSS 4.0 vector indicates network attack vector, no privileges or user interaction required, and high impact on confidentiality, integrity, availability, and security requirements. No patch or official remediation level has been published yet.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to perform arbitrary file read and write operations as root, leading to full system compromise via remote code execution. This poses a critical risk to confidentiality, integrity, and availability of affected systems running vulnerable versions of SparkView.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the SparkView service and disable RDP drive redirection if possible to reduce exposure.
