Summary

CVE-2025-65897 is a high-severity Path Traversal (CWE-22) vulnerability in Zhaoyachao Zdh Web. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 48% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2025-65897 affects zdh_web, an open-source data collection, processing, monitoring, scheduling, and management platform, through version 5.6.17. The vulnerability stems from insufficient validation of file upload paths in the application, enabling authenticated users to write arbitrary files to the server file system. This issue, associated with CWE-22 (Improper Limitation of a Pathname to a Restricted Directory) and CWE-434 (Comparison of Classes by Name), carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for confidentiality, integrity, and availability impacts.

An attacker with low-privilege authenticated access (PR:L) can exploit this over the network (AV:N) with low complexity and no user interaction required. By crafting malicious file upload paths, they can place files in arbitrary locations on the server, overwriting critical system files. This may lead to privilege escalation by modifying configuration files or executables, or remote code execution if suitable files like scripts or binaries are overwritten or uploaded.

Mitigation details are available in the project's GitHub repository at https://github.com/zhaoyachao/zdh_web. A fix appears in commit b2423378a8bf83f159f19ce4e14eac71c939793a, with related discussion in issue #40 and pull request #39, recommending upgrade to a patched version beyond 5.6.17.

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes special path elements before pathname construction occurs.

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

Least functionality restricts the file types and automatic processing capabilities the system will accept.

SC-18 Mobile Code partial match

Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

PR.PS-05 mostly match
prevents

Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.

PR.PS-01 partial match
prevents

Hardened configuration baselines can enforce allowed file types and processing rules.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.PS-06 partial match
prevents

Secure development practices include input validation and file-type restrictions that prevent this weakness.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
