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

A critical vulnerability, CVE-2025-47916, has been discovered in Invision Community 5.0.0. This vulnerability allows for remote code execution via specially crafted template strings to the themeeditor.php file. Any system running versions before 5.0.7 of Invision Community is susceptible to this exploit, potentially leading to full system<\/a> compromise or data leakage.
\nThe severity of this vulnerability<\/a> cannot be overstated. It permits unauthenticated users to inject<\/a> and execute arbitrary PHP code, compromising the security of the affected systems, and potentially leading to unauthorized access to sensitive data. This vulnerability poses a significant risk<\/a> to any organization running the affected versions of Invision Community.<\/p>\n

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

CVE ID: CVE-2025-47916
\nSeverity: Critical, CVSS score of 10.0
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system<\/a> compromise and data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Invision Community | 5.0.0 to 5.0.6<\/p>\n

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

The vulnerability lies within the themeeditor.php file<\/a>, specifically within the themeeditor controller. Unauthenticated users<\/a> can invoke a protected method named customCss, which accepts the value of the content parameter and passes it to the Theme::makeProcessFunction() method.
\nThis method evaluates the content parameter using the template engine, which can be exploited by attackers to inject arbitrary PHP code<\/a>. By supplying specially crafted template strings, an attacker can execute this arbitrary PHP code<\/a> remotely, potentially leading to system compromise.<\/p>\n

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

Below is a conceptual example of how this vulnerability might be exploited:<\/p>\n

POST \/applications\/core\/modules\/front\/system\/themeeditor.php HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\ncontent={ \"customCss\": \"\" }<\/code><\/pre>\n
In this example, the attacker sends a POST request to the vulnerable<\/a> themeeditor.php endpoint, using the content parameter to inject PHP code. This code, once executed, would allow the attacker to run arbitrary commands on the system<\/a>.<\/p>\n
Remediation<\/strong><\/p>\n
The most direct resolution for this vulnerability<\/a> is to apply the vendor-supplied patch. Invision Community has released version 5.0.7 to address this vulnerability<\/a>, and all users should update as soon as possible.
\nAs a temporary measure, web application firewalls (WAFs) or intrusion detection systems (IDSs) can be configured to detect and block attempts to exploit this vulnerability<\/a>. However, these measures are not a substitute for patching the underlying vulnerability<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
