CriticalCVSS 10.0Exploitation Probability (EPSS)
Low risk21th percentile - higher than 21% of all known CVEs
Summary
Boxlite prior to version 0.9.0 does not restrict kernel capabilities inside the container, allowing malicious code to remount directories in rw mode and gain write access to read-only directories. Fixed in version 0.9.0.
Risk Assessment
Malicious code running in the sandbox can modify files in directories that should be read-only, potentially breaking isolation and leading to privilege escalation.
Recommendation
Upgrade Boxlite to version 0.9.0 or later.
Original NVD description (English source)
Boxlite is a sandbox service that allows users to create lightweight virtual machines (Boxes) and launch OCI containers within them to run untrusted code. Prior to version 0.9.0, Boxlite does not restrict the kernel capabilities available inside the container, malicious code can remount the directory in rw mode, thereby gaining write access to that directory. This allows malicious code to perform arbitrary write operations on directories that should be read-only. This issue has been patched in version 0.9.0.
