- Severity: CVSS 9.3 (Critical), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=total

## Affected

- Guangzhou Red Sea Cloud Computing Co., Ltd. Red Sea Cloud eHR: all versions

## Description

Redsea Cloud eHR contains an arbitrary file upload vulnerability that allows unauthenticated attackers to achieve remote code execution by uploading malicious files through the PtFjk.mob servlet endpoint. Attackers can submit a multipart POST request with a JSP webshell disguised using a spoofed image/jpeg Content-Type to bypass the absence of extension and MIME type validation, with the uploaded file stored at a predictable path under the uploadfile directory and executed directly by the web server. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-11-03 (UTC).
