Summary

efs-utils and aws-efs-csi-driver have race condition during concurrent TLS mounts

Details

Impact

A potential race condition issue exists within the Amazon EFS mount helper in efs-utils versions v1.34.3 and below, and aws-efs-csi-driver versions v1.4.7 and below. When using TLS to mount file systems, the mount helper allocates a local port for stunnel to receive NFS connections prior to applying the TLS tunnel. In affected versions, concurrent mount operations can allocate the same local port, leading to either failed mount operations or an inappropriate mapping from an EFS customer’s local mount points to that customer’s EFS file systems.

Affected versions: efs-utils <= v1.34.3, aws-efs-csi-driver <= v1.4.7

Patches

The patches are included in efs-utils version v1.34.4 and newer, and in aws-efs-csi-driver v1.4.8 and newer.

Workarounds

There is no recommended work around. We recommend affected users update the installed version of efs-utils to v1.34.4+ or aws-efs-csi-driver to v1.4.8+ to address this issue.

Vulnerability from cvelistv5 – Published: 2022-12-28 06:46 – Updated: 2025-04-11 15:45

Title

Race condition during concurrent TLS mounts in efs-utils

Summary

efs-utils is a set of Utilities for Amazon Elastic File System (EFS). A potential race condition issue exists within the Amazon EFS mount helper in efs-utils versions v1.34.3 and below. When using TLS to mount file systems, the mount helper allocates a local port for stunnel to receive NFS connections prior to applying the TLS tunnel. In affected versions, concurrent mount operations can allocate the same local port, leading to either failed mount operations or an inappropriate mapping from an EFS customer’s local mount points to that customer’s EFS file systems. This issue is patched in version v1.34.4. There is no recommended work around. We recommend affected users update the installed version of efs-utils to v1.34.4 or later.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
