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

The CVE-2015-10144 vulnerability pertains to the popular WordPress plugin, Responsive Thumbnail Slider. This plugin, widely used for enhancing website aesthetics, has a significant flaw. It allows for unauthorized file<\/a> uploads due to an absence of file type sanitization, specifically in versions up to 1.0.1.
\nThe implications of this vulnerability are serious<\/a> and far-reaching. Any authenticated attacker with subscriber-level access or above can potentially<\/a> exploit this flaw. This can result in system<\/a> compromise or data leakage, leading to serious repercussions for the affected organization.<\/p>\n

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

CVE ID: CVE-2015-10144
\nSeverity: High – CVSS 8.8
\nAttack Vector: Network
\nPrivileges Required: Low (Subscriber-level access or above)
\nUser Interaction: Required
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Responsive Thumbnail Slider Plugin for WordPress<\/a> | Up to 1.0.1<\/p>\n

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

An authenticated attacker can exploit this vulnerability by uploading a malicious file<\/a> with a double extension via the image uploader feature. The plugin does not perform proper file type sanitization, allowing the attacker to execute arbitrary code<\/a> on the server. The executed code can then lead<\/a> to unauthorized access to sensitive data or even full control over the affected system.<\/p>\n

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

Below is a conceptual example of a malicious HTTP request that an attacker might use to exploit this vulnerability<\/a>:<\/p>\n

POST \/wp-content\/plugins\/responsive-thumbnail-slider\/upload.php HTTP\/1.1\nHost: target.example.com\nContent-Type: multipart\/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\n------WebKitFormBoundary7MA4YWxkTrZu0gW\nContent-Disposition: form-data; name=\"imagefile\"; filename=\"malicious.php.jpg\"\nContent-Type: image\/jpeg\n{ \"malicious_payload\": \"...\" }\n------WebKitFormBoundary7MA4YWxkTrZu0gW--<\/code><\/pre>\n
In this example, an attacker uploads a file<\/a> with a double extension, bypassing the plugin’s file type checks and executing the malicious payload on the server.
\nAll WordPress websites using the affected versions of the Responsive Thumbnail Slider plugin<\/a> should immediately apply the vendor patch to rectify this issue. Alternatively, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation.<\/p>\n","protected":false},"excerpt":{"rendered":"
