| 标题 | GreenCMS 2.3.0603 CWE-79 - Cross-site Scripting |
|---|
| 描述 | A stored Cross-Site Scripting (XSS) vulnerability was discovered in GreenCMS version 2.3.0603. The vulnerability originates from insufficient input sanitization in the "Link" parameter of the menu editor. Although the htmlspecialchars() function is used, the lack of the ENT_QUOTES flag results in the failure to escape single quotes ('). This allows an authenticated attacker to inject malicious JavaScript by closing the existing attribute with a single quote and injecting a new event handler. |
