DescriptionCVE.org

A vulnerability was found in DTStack Taier 1.4.0. Affected by this vulnerability is the function Paths.ge of the file FileChunkController.java of the component Chunk-Check Endpoint. The manipulation of the argument Name results in path traversal. The attack may be launched remotely. The exploit has been made public and could be used.

AnalysisAI

Path traversal in DTStack Taier 1.4.0's Chunk-Check Endpoint exposes the server's filesystem to remote unauthenticated attackers who can manipulate the Name parameter in FileChunkController.java to escape the intended upload directory. The Java Paths.get() function processes attacker-controlled input without sanitization, enabling directory traversal sequences to reference arbitrary files accessible to the Taier process. …

Vulnerability AssessmentAI

Exploitation No special authentication is required - the CVSS 4.0 vector PR:N and UI:N confirm the Chunk-Check Endpoint is accessible to unauthenticated remote attackers. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector AV:N/AC:L/AT:N/PR:N/UI:N with VC:L/VI:L/VA:L yields a score of 6.9, reflecting unauthenticated, low-complexity network exploitation with limited per-impact ratings. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated remote attacker sends a crafted HTTP request to Taier's Chunk-Check Endpoint with the Name parameter set to a path traversal sequence such as '../../etc/passwd'. The Paths.get() call in FileChunkController.java resolves the manipulated path outside the intended upload directory, exposing the targeted file's existence or contents. …
Remediation No vendor-released patch version has been independently confirmed at time of analysis; the fix reference points to a GitHub issue (https://github.com/DTStack/Taier/issues/1203) rather than a tagged release, so an upstream fix may be in progress but a patched version number is not yet available. … Detailed patch versions, workarounds, and compensating controls in full report.
