![]() ![]() By bypassing CSP, attackers can circumvent the security measures put in place by the web application and execute their malicious code. Furthermore, the fact that the vulnerability bypasses the Content Security Policy (CSP) makes it more dangerous, as CSP is an important security mechanism used to prevent cross-site scripting attacks. This can lead to unauthorized access to sensitive information and data, as well as the ability to perform actions on behalf of the victim. An attacker can exploit the vulnerability to inject code into the victim's browser session, allowing the attacker to take over the victim's account without their knowledge or consent. In this specific case, the vulnerability allows for a trivial account takeover attack. This means that an attacker can steal sensitive data, such as login credentials or personal information, or perform unauthorized actions on behalf of the victim, such as modifying or deleting data. The vulnerability allows attackers to inject malicious code into web pages, which can be executed in the context of the victim's browser session. The vulnerability can be exploited to perform a trivial account takeover attack. This vulnerability report describes a reflected XSS vulnerability with full CSP bypass in Nextcloud installations using the recommended bundle. If a remote attacker who can conduct a man-in-the-middle attack connects the product to a malicious server and sends a specially crafted data, an arbitrary OS command may be executed on the system where the product is installed.Ĭollabora Online is a collaborative online office suite based on LibreOffice technology. OS command injection vulnerability exists in WPS Office version 10. Microsoft Office Remote Code Execution Vulnerability Users should upgrade to Collabora Online 22.05.13 or higher Collabora Online 21.11.9.1 or higher Collabora Online 6.4.27 or higher to receive a patch. The administrator JSON web token (JWT) used for the websocket connection could be leaked through this flaw. Later, if an administrator opened the admin console and navigated to the history page, the document name was injected as unescaped HTML and executed as a script inside the context of the admin console. An attacker could create a document with an XSS payload as a document name. ![]() ![]() A stored cross-site scripting (XSS) vulnerability was found in Collabora Online prior to versions 22.05.13, 21.11.9.1, and 6.4.27. Collabora Online is a collaborative online office suite. ![]()
