CVE-2025-34040 Scanner

Zhiyuan OA Platform is a comprehensive management software used by organizations around the globe for office administration tasks. Various companies implement it to streamline communication, document management, and workflow. With its robust features, it serves larger enterprises looking for efficient internal processes. The platform facilitates document sharing, task management, and communication all in one place. Its broad adoption is due to its flexible integration capabilities with various enterprise systems. However, its complexity also makes it susceptible to vulnerabilities that can be exploited if not appropriately addressed.

The Arbitrary File Upload vulnerability in Zhiyuan OA Platform permits attackers to upload malicious files to the server. This exploit is notable because it involves improper validation of parameters during file uploads. Attackers can maneuver such a weakness to upload files outside intended directories, potentially leading to remote code execution. This vulnerability is especially alarming in the context of corporate environments where sensitive data might be at risk. The existence of this weakness highlights a significant security misstep in the platform's handling of file inputs. Addressing this critical issue is paramount for ensuring the security of enterprise infrastructures relying on Zhiyuan OA.

Technical details reveal that the vulnerability arises from insufficient validation of the realFileType and fileId parameters in the wpsAssistServlet interface. Attackers exploit this by crafting multipart upload requests that allow path traversal. This permits uploading of JSP files, which are executed as code, granting potentially unauthorized access to server resources. The flaw lies in the improper handling of input paths, which does not adequately check for directories into which files are being uploaded. If leveraged effectively, the attacker can manipulate the application to serve malicious files under the guise of legitimate operations. Proper restrictions and file validation should be implemented to prevent such file uploads.

Exploiting this vulnerability can have severe effects, particularly if attackers gain unchecked access through uploaded files. Possible impacts include full server compromise, leading to data breaches, unauthorized transactions, and further network penetrations. Sensitive information stored on the platform could be extracted, manipulated, or destroyed, causing reputational harm and financial loss. The integrity of the systems utilizing the platform would be jeopardized, impacting all levels of operation. Furthermore, attackers could use compromised systems as a launchpad for initiating attacks against other interconnected services. Mitigation strategies should focus on rectifying the validation process in the file upload components of the application.
