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

The AIHub WordPress theme suffers from a critical vulnerability that exposes users to significant security risks. This theme, used by numerous WordPress sites globally, contains a flaw that leaves it susceptible to arbitrary file uploads from unauthenticated attackers. The potential consequences of this security flaw can be dire, with the risk of remote code<\/a> execution on the affected server being a significant threat. This vulnerability, identified as CVE-2025-1093, is a pressing issue that demands immediate attention due to its high severity<\/a>.<\/p>\n

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

CVE ID: CVE-2025-1093
\nSeverity: Critical (9.8 CVSS)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Possible system compromise<\/a> and data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

AIHub Theme for WordPress<\/a> | Up to and including 1.3.7<\/p>\n

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

The vulnerability resides in the generate_image function of the AIHub theme<\/a>. This function lacks proper file type validation, thereby providing a loophole for attackers to upload arbitrary files<\/a>. An unauthenticated attacker can exploit this vulnerability by sending a specifically crafted HTTP POST request to upload<\/a> a malicious file to the server. Once uploaded, this file could be executed on the server, leading to possible system<\/a> compromise or data leakage.<\/p>\n

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

Below is a conceptual example of how this vulnerability might be exploited<\/a>. The attacker sends a malicious payload embedded within an HTTP POST request to the vulnerable<\/a> endpoint.<\/p>\n

POST \/wp-content\/themes\/aihub\/generate_image.php HTTP\/1.1\nHost: target.example.com\nContent-Type: multipart\/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\n------WebKitFormBoundary7MA4YWxkTrZu0gW\nContent-Disposition: form-data; name=\"file\"; filename=\"shell.php\"\nContent-Type: application\/php\n\n------WebKitFormBoundary7MA4YWxkTrZu0gW--<\/code><\/pre>\n
In this example, the attacker uploads a PHP shell file<\/a> that can execute arbitrary shell commands controlled by the attacker.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
It is recommended to apply the vendor patch as soon as it is available to fix this vulnerability<\/a>. Until then, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation measures. These systems can detect and block malicious file uploads<\/a>, thereby preventing the exploitation of this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
