DescriptionCVE.org

A vulnerability was determined in DTStack Taier 1.4.0. Affected by this issue is the function FileUtils.deleteDirectory of the file ClusterController.java of the component Cluster Creation. This manipulation of the argument clusterName causes path traversal. Remote exploitation of the attack is possible. Upgrading to version 1.5.0 can resolve this issue. Patch name: ec8c59c76aceb04ab3080543ab2d9c6a4b674729. The affected component should be upgraded.

AnalysisAI

Path traversal in DTStack Taier 1.4.0 allows an authenticated administrative user to supply a crafted clusterName containing directory-escape sequences during cluster creation, causing FileUtils.deleteDirectory to operate on arbitrary filesystem paths outside the intended temp directory. The CVSS 4.0 score of 5.1 with PR:H reflects the constrained attack surface: only users with cluster management privileges can trigger the flaw. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated session with high-privilege cluster management rights in Taier, as confirmed by CVSS PR:H. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 5.1 with PR:H accurately characterises the constrained real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated Taier administrator submits a cluster creation request with a crafted clusterName value such as '../../var/lib/taier-kerberos' to the Cluster Creation API endpoint. Taier's ConsoleComponentService builds an unsanitized path by concatenating the temp directory with the attacker-controlled name, then passes the result to FileUtils.deleteDirectory(), deleting an arbitrary directory on the server filesystem. …
Remediation Upgrade to DTStack Taier 1.5.0, available at https://github.com/DTStack/Taier/releases/tag/v1.5.0, which applies all three path traversal fixes under commit ec8c59c76aceb04ab3080543ab2d9c6a4b674729 (https://github.com/DTStack/Taier/commit/ec8c59c76aceb04ab3080543ab2d9c6a4b674729). … Detailed patch versions, workarounds, and compensating controls in full report.
