CVE-2026-31817 Details
Description
OliveTin gives access to predefined shell commands from a web interface. Prior to 3000.11.2, when the saveLogs feature is enabled, OliveTin persists execution log entries to disk. The filename used for these log files is constructed in part from the user-supplied UniqueTrackingId field in the StartAction API request. This value is not validated or sanitized before being used in a file path, allowing an attacker to use directory traversal sequences (e.g., ../../../) to write files to arbitrary locations on the filesystem. This vulnerability is fixed in 3000.11.2.
A vulnerability in OliveTin prior to version 3000.11.2 allows for arbitrary file writing through directory traversal. When the saveLogs feature is enabled, OliveTin logs execution entries to disk using a filename derived from the user-supplied UniqueTrackingId in the StartAction API request. This ID is not validated before being used in the file path, enabling attackers to manipulate the path and write files to unintended locations on the filesystem. OliveTin often runs as root in Docker containers, potentially giving attackers access to the entire filesystem.
Users should update to OliveTin version 3000.11.2 or later, where this vulnerability has been fixed.
