CVE-2025-13275: Critical File Upload Vulnerability Exposes Iqbolshoh php-business-website

by

Overview

CVE-2025-13275 identifies a medium-severity security vulnerability affecting Iqbolshoh php-business-website up to version 10677743a8dfc281f85291a27cf63a0bce043c24. This vulnerability allows for unrestricted file uploads, potentially leading to remote code execution and other malicious activities.

Technical Details

The vulnerability exists within the /admin/about.php file of the affected software. An attacker can exploit this flaw by uploading arbitrary files without proper validation, bypassing security measures intended to restrict file types and sizes. The lack of input sanitization on uploaded files allows an attacker to upload executable files (e.g., PHP, .exe) that can then be accessed and executed by the web server, potentially compromising the entire system.

The software uses continuous delivery through a rolling release, meaning specific version numbers are unavailable for both affected and updated releases. This makes identifying vulnerable installations more challenging.

CVSS Analysis

The Common Vulnerability Scoring System (CVSS) assigns this vulnerability a score of 4.7, indicating a MEDIUM severity. This score considers the following factors:

  • Attack Vector: Network (AV:N) – The attack can be initiated remotely.
  • Attack Complexity: Low (AC:L) – The vulnerability is relatively easy to exploit.
  • Privileges Required: None (PR:N) – No privileges are required to exploit the vulnerability.
  • User Interaction: None (UI:N) – No user interaction is required to trigger the vulnerability.
  • Scope: Unchanged (S:U) – A successful exploit only affects the vulnerable component.
  • Confidentiality Impact: None (C:N)
  • Integrity Impact: Low (I:L)
  • Availability Impact: None (A:N)

Possible Impact

Successful exploitation of this vulnerability can have significant consequences:

  • Remote Code Execution (RCE): Attackers can execute arbitrary code on the server, potentially gaining full control.
  • Website Defacement: Attackers can upload malicious content to deface the website.
  • Data Theft: If the server hosts sensitive data, attackers can potentially access and steal it.
  • Malware Distribution: The compromised server can be used to distribute malware to website visitors.

Mitigation or Patch Steps

Due to the rolling release nature of the software, specific patches or version updates are not available. However, the following mitigation steps are highly recommended:

  • Input Validation: Implement strict input validation on the /admin/about.php file and any other file upload functionalities. Specifically, validate the file extension, MIME type, and file size. A whitelist approach is recommended, only allowing specific, safe file types.
  • File Storage Security: Store uploaded files outside the web root and use a non-executable file extension. This prevents direct execution of uploaded files.
  • Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities.
  • Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to filter malicious traffic and block attempts to exploit the vulnerability.
  • Least Privilege Principle: Ensure that the web server process runs with the least privileges necessary.
