Detailsinfo

A vulnerability classified as critical was found in Aranda ASDK API 8.6. Affected by this vulnerability is an unknown functionality of the file /ASDKAPI/api/v8.6/item/addfile. The manipulation with an unknown input leads to a remote privilege escalation vulnerability. The CWE definition for the vulnerability is CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

An issue in Aranda Service Desk Web Edition (ASDK API 8.6) allows authenticated attackers to achieve remote code execution due to improper validation of uploaded files. An authenticated user can upload a crafted web.config file by sending a crafted POST request to /ASDKAPI/api/v8.6/item/addfile, which is processed by the ASP.NET runtime. The uploaded configuration file alters the execution context of the upload directory, enabling compilation and execution of attacker-controlled code (e.g., generation of an .aspx webshell). This allows remote command execution on the server without user interaction beyond authentication, impacting both On-Premise and SaaS deployments. The vendor has fixed the issue in Aranda Service Desk V8 8.30.6.
