Low risk9th percentile — higher than 9% of all known CVEs
Summary
Boxlite is a sandbox service that allows users to create lightweight virtual machines and launch OCI containers. Prior to version 0.9.0, Boxlite does not restrict kernel capabilities inside the container, allowing malicious code to gain write access to directories that should be read-only.
Risk Assessment
Malicious code can take control of directories, leading to potential security breaches and data integrity loss. Organizations may be vulnerable to attacks exploiting this vulnerability for unauthorized write operations.
Recommendation
It is recommended to update Boxlite to version 0.9.0 or later to mitigate this vulnerability. Additionally, conducting a security audit of existing containers to assess potential threats is advisable.
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.
