8.1 HIGH

Network-reachable API needing only a low-privilege account (PR:L, AC:L); arbitrary file write yields high integrity and availability impact but no data disclosure, so C:N.

DescriptionCVE.org

DataEase is an open source data visualization and analysis tool. Prior to 2.10.23, DataEase template saves call TemplateManageService#save, StaticResourceServer#saveFilesToServe, and the /de2api/templateManage/save endpoint with attacker-controlled staticResource names and Base64 content, allowing path traversal and arbitrary file writes because only / was used when extracting the file name. This issue is fixed in version 2.10.23.

AnalysisAI

Arbitrary file write in DataEase (open-source BI/data-visualization platform) before 2.10.23 lets an authenticated user (PR:L) abuse the /de2api/templateManage/save template-save endpoint to write attacker-controlled Base64 content to arbitrary filesystem paths. Because StaticResourceServer#saveFilesToServe extracted the filename using only a forward-slash split, crafted staticResource names containing traversal sequences or backslashes escaped the intended static-resource directory. …

Vulnerability AssessmentAI

Exploitation Requires an authenticated DataEase account with permission to reach the template-save flow (POST /de2api/templateManage/save invoking TemplateManageService#save → StaticResourceServer#saveFilesToServe); this maps to the CVSS PR:L requirement, so it is not exploitable by fully unauthenticated attackers. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The vendor CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:H/SA:H, score 8.5) indicates a network-reachable, low-complexity attack requiring only low-level authentication, with high integrity and availability impact and no confidentiality impact - consistent with an arbitrary-file-write primitive rather than data theft. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with a low-privilege DataEase account submits a crafted template-save request to /de2api/templateManage/save containing a staticResource name with traversal or backslash sequences and Base64-encoded malicious content. Because the server only split on '/', the file is written outside the static-resource directory - for example dropping a webshell into a servlet-served path or overwriting a configuration file - leading to code execution or integrity compromise. …
Remediation Vendor-released patch: upgrade to DataEase 2.10.23, which replaces the naive filename extraction with a backslash-normalizing extractFileName() helper (commit d34f413ef047bd275909d67310d200cbc8ae31ba; release https://github.com/dataease/dataease/releases/tag/v2.10.23; advisory https://github.com/dataease/dataease/security/advisories/GHSA-83fh-fgh3-g9f9). … Detailed patch versions, workarounds, and compensating controls in full report.
