### Summary One of the sample scripts in PhpSpreadsheet is susceptible to a cross-site scripting (XSS) vulnerability due to improper handling of input where a number is expected leading to formula injection. ### Details The following [code](https://github.com/PHPOffice/PhpSpreadsheet/blob/d50b8b5de7e30439fb57eae7df9ea90e79fa0f2d/samples/Basic/45_Quadratic_equation_solver.php#L56) in `45_Quadratic_equation_solver.php` concatenates the user supplied parameters directly into spreadsheet formulas. This allows an attacker to take control over the formula and output unsanitized data into the page, resulting in JavaScript execution. ``` $discriminantFormula = '=POWER(' . $_POST['B'] . ',2) - (4 * ' . $_POST['A'] . ' * ' . $_POST['C'] . ')'; $discriminant = Calculation::getInstance()->calculateFormula($discriminantFormula); $r1Formula = '=IMDIV(IMSUM(-' . $_POST['B'] . ',IMSQRT(' . $discriminant . ')),2 * ' . $_POST['A'] . ')'; $r2Formula = '=IF(' . $discriminant . '=0,"Only one root",IMDIV...

### Impact The cookie name could be used to set other fields of the cookie, resulting in an unexpected cookie value. For example, `serialize("userName=<script>alert('XSS3')</script>; Max-Age=2592000; a", value)` would result in `"userName=<script>alert('XSS3')</script>; Max-Age=2592000; a=test"`, setting `userName` cookie to `<script>` and ignoring `value`. A similar escape can be used for `path` and `domain`, which could be abused to alter other fields of the cookie. ### Patches Upgrade to 0.7.0, which updates the validation for `name`, `path`, and `domain`. ### Workarounds Avoid passing untrusted or arbitrary values for these fields, ensure they are set by the application instead of user input. ### References * https://github.com/jshttp/cookie/pull/167

### Summary The `HtmlGenerator` class is subject to potential cross-site scripting (XSS) attack through a parsed malformed Minecraft server MOTD. ### Context Minecraft server owners can set a so-called MOTD (Message of the Day) for their server that appears next to the server icon and below the server name on the multiplayer server list of a player's Minecraft client. The Minecraft server sends the MOTD in the `description` property of the [Status Response](https://wiki.vg/Server_List_Ping#Status_Response) packet. The [jgniecki/MinecraftMotdParser](https://github.com/jgniecki/MinecraftMotdParser) PHP library is able to parse the value of the `description` property, which can be either a string or an array of text components. By utilizing the aforementioned `HtmlGenerator` class, it is also able to transform the value into an HTML string that can be used to visualize the MOTD on a web page. ### Details The `HtmlGenerator` iterates through objects of `MotdItem` that are contained in an...

Computer Laboratory Management System 2024 version 1.0 suffers from a cross site scripting vulnerability.

A new high-severity security flaw has been disclosed in the LiteSpeed Cache plugin for WordPress that could enable malicious actors to execute arbitrary JavaScript code under certain conditions. The flaw, tracked as CVE-2024-47374 (CVSS score: 7.2), has been described as a stored cross-site scripting (XSS) vulnerability impacting all versions of the plugin up to and including 6.5.0.2. It was

### Impact This vulnerability allows an attacker to inject arbitrary HTML/JavaScript code through the media download URL in Sulu CMS. It affects the SuluMediaBundle component. The vulnerability is a Reflected Cross-Site Scripting (XSS) issue, which could potentially allow attackers to steal sensitive information, manipulate the website's content, or perform actions on behalf of the victim. ### Patches The problem has not been patched yet. Users should upgrade to patched versions once they become available. Currently affected versions are: * 2.6.4 * 2.5.20 ### Workarounds Until an official patch is released, users can implement additional input validation and output encoding for the 'slug' parameter in the MediaStreamController's downloadAction method. Alternatively, configuring a Web Application Firewall (WAF) to filter potentially malicious input could serve as a temporary mitigation. ### References * GitHub repository: https://github.com/sulu/sulu * Vulnerable code: https://g...
