CVE-2025-7898: Critical Unrestricted File Upload Vulnerability in iDentSoft 2.0
This blog post discusses a critical security vulnerability, identified as CVE-2025-7898, affecting Codecanyon's iDentSoft 2.0. This flaw allows attackers to upload arbitrary files to the server, potentially leading to remote code execution and complete system compromise.
🔍 TL;DR Summary
iDentSoft 2.0 is vulnerable to unrestricted file uploads via the 'photo' parameter on the Account Setting Page. An attacker with high privileges can upload malicious files, leading to potential remote code execution. A proof-of-concept exploit is publicly available.
🚨 Vulnerability Details
- CVE ID: CVE-2025-7898
- Description: An unrestricted file upload vulnerability exists in Codecanyon iDentSoft 2.0 within the Account Setting Page's
/clinica/profile/updateSettingfunctionality. By manipulating thephotoargument, a high privileged user can upload any file type without proper validation. - CVSS Score: 4.7 (Medium)
- CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L
- CVSS Explanation:
- AV:N (Attack Vector: Network) - The vulnerability can be exploited over the network.
- AC:L (Attack Complexity: Low) - Exploitation requires minimal effort.
- PR:H (Privileges Required: High) - Attacker needs administrative access to exploit this vulnerability.
- UI:N (User Interaction: None) - No user interaction is required for successful exploitation.
- S:U (Scope: Unchanged) - An exploited vulnerability can only affect resources managed by the same security authority.
- C:L (Confidentiality Impact: Low) - Limited information disclosure.
- I:L (Integrity Impact: Low) - Limited data modification possible.
- A:L (Availability Impact: Low) - Limited disruption to service.
- Exploit Requirements: The attacker must be authenticated with high privileges (e.g., administrator role).
- Affected Vendor: Codecanyon
- Affected Product: iDentSoft
- Affected Version: 2.0
- CWE: CWE-434 - Unrestricted Upload of File with Dangerous Type
CWE-434 describes a scenario where the application allows users to upload files without proper validation of the file type. This can lead to the execution of arbitrary code on the server if an attacker uploads a malicious script (e.g., a PHP file) and then accesses it through the web server.
📅 Timeline of Events
- 2025-07-20: Vulnerability publicly disclosed.
- 2025-07-20: CVE ID assigned (CVE-2025-7898).
- 2025-07-20: Proof-of-concept exploit released.
🧠 Exploitability & Real-World Risk
This vulnerability is highly exploitable because a proof-of-concept is publicly available. An attacker with administrative access can easily upload a malicious file (e.g., a PHP webshell) and gain remote code execution. This could lead to data theft, website defacement, or complete server takeover. Given the nature of dental clinic software, sensitive patient data is at risk.
🛠️ Recommendations
- Apply Patch: Immediately apply the patch or update released by iDentSoft (if available).
- Input Validation: Implement strict input validation on the
photoparameter to only allow specific image types (e.g., .jpg, .png) and sizes. - File Storage Security: Store uploaded files outside the webroot to prevent direct access.
- Regular Security Audits: Conduct regular security audits to identify and address potential vulnerabilities.
- Web Application Firewall (WAF): Consider implementing a WAF to filter malicious requests.
🧪 Technical Insight
The vulnerability lies in the lack of proper file type validation during the upload process. The/clinica/profile/updateSetting endpoint doesn't verify the file extension or MIME type of the uploaded file. This allows an attacker to bypass intended security measures by uploading a PHP script disguised as an image. Once uploaded, the attacker can access the script through the web server and execute arbitrary commands.
