Silverpeas Core vulnerabilities

The 'Create a Space' feature in Silverpeas Core 6.3.1 is reserved for administrators but suffers from broken access control, allowing any authenticated user to create a space by navigating to the correct URL.

Silverpeas Core 6.3.1 is vulnerable to Cross-Site Request Forgery (CSRF) via the Domain SQL Create function. An attacker can exploit this flaw to perform unauthorized actions on behalf of an authenticated user.

A vulnerability in Silverpeas Core 6.3.1 administrative 'Bin' feature allows a low-privileged user to access the bin, revealing all deleted spaces. The user can then restore or permanently delete these spaces.

Silverpeas Core 6.3.1 is vulnerable to Cross Site Scripting (XSS) via the message/notification feature. An attacker can inject malicious JavaScript code into message content.

The notification/messaging feature of Silverpeas Core 6.3.1 does not enforce access control on the ID parameter. This allows an attacker to read all messages sent between other users; including those sent only to administrators.

The 'userModify' feature in Silverpeas Core 6.3.1 is vulnerable to Cross-Site Request Forgery (CSRF) leading to privilege escalation. If an administrator visits a malicious URL while authenticated, the attacker can become an administrator user.

Silverpeas Core 6.3.1 has an incorrect access control vulnerability in the 'Porlet Deployer' component, allowing administrators to deploy .WAR portlets. This could lead to unauthorized code execution or privilege escalation.

Silverpeas Core 6.3.1 and below contain an incorrect access control vulnerability. An attacker with low privileges can execute the administrator-only function of enabling maintenance mode, making the application unavailable to all users.
