DescriptionCVE.org

A flaw has been found in WuzhiCMS up to 4.1.0. Affected by this vulnerability is the function config/listimage of the file /index.php?m=attachment&f=index&v=upload of the component Attachment API. Executing a manipulation can lead to information disclosure. The attack can be launched remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Information disclosure in WuzhiCMS up to version 4.1.0 exposes sensitive server-side data through the Attachment API's config/listimage function, reachable at /index.php?m=attachment&f=index&v=upload. Remote unauthenticated attackers can exploit this endpoint without any privileges or user interaction, as confirmed by a publicly available proof-of-concept published via a GitHub issue report. …

Vulnerability AssessmentAI

Exploitation No special conditions are required for exploitation. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 6.9 (Medium) with vector AV:N/AC:L/AT:N/PR:N/UI:N and confidentiality impact VC:L reflects an unauthenticated, remotely exploitable flaw requiring no special conditions, though the impact ceiling is low - integrity and availability are unaffected (VI:N/VA:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker sends a crafted HTTP GET request to a publicly accessible WuzhiCMS instance targeting `/index.php?m=attachment&f=index&v=upload`, triggering the `config/listimage` function to return sensitive attachment configuration data or file listing information. A proof-of-concept has been published on GitHub (issue #217), meaning the exploit methodology is publicly documented and requires minimal attacker sophistication. …
Remediation No vendor-released patch has been identified at time of analysis - the project was notified via GitHub issue but has not responded. … Detailed patch versions, workarounds, and compensating controls in full report.
