The BMS/BAS controller suffers from an arbitrary file deletion vulnerability. Input passed to the 'file' parameter in calendarFileDelete.php is not properly sanitised before being used to delete calendar files. This can be exploited by an unauthenticated attacker to delete files with the permissions of the web server using directory traversal sequences passed within the affected POST parameter.

### Summary `\PhpOffice\PhpSpreadsheet\Writer\Html` does not sanitize "javascript:" URLs from hyperlink `href` attributes, resulting in a Cross-Site Scripting vulnerability. ### PoC Example target script: ``` <?php require 'vendor/autoload.php'; $reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader("Xlsx"); $spreadsheet = $reader->load(__DIR__ . '/book.xlsx'); $writer = new \PhpOffice\PhpSpreadsheet\Writer\Html($spreadsheet); print($writer->generateHTMLAll()); ``` Save this file in the same directory: [book.xlsx](https://github.com/PHPOffice/PhpSpreadsheet/files/15099763/book.xlsx) Open index.php in a web browser and click on both links. The first demonstrates the vulnerability in a regular hyperlink and the second in a HYPERLINK() formula.

### Summary Event log data is not properly sanitized leading to stored Cross-Site Scripting (XSS) vulnerability. ### Details - file: https://github.com/saltcorn/saltcorn/blob/v1.0.0-beta.13/packages/server/routes/eventlog.js#L445 ```js router.get( "/:id", isAdmin, error_catcher(async (req, res) => { const { id } = req.params; const ev = await EventLog.findOneWithUser(id); send_events_page({ [...] contents: { type: "card", contents: [...] ) + div( { class: "eventpayload" }, ev.payload ? pre(JSON.stringify(ev.payload, null, 2)) : "" //<--- ), }, }); }) ``` ### PoC The following PoC demonstrates how a non-admin user with permission to read/write on a table can inject malicious javascript code that will be executed in the event log admin panel if event logs are enabled. To demonstrate this issue, we need to prepare some components. The following steps should be ...

### 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...

This script exploits the issue noted in CVE-2024-45409 that allows an unauthenticated attacker with access to any signed SAML document issued by the IDP to forge a SAML Response/Assertion and gain access as any user on GitLab. Ruby-SAML versions below or equal to 12.2 and versions 1.13.0 through 1.16.0 do not properly verify the signature of the SAML Response.

ABB Cylon Aspect versions 3.08.01 and below suffer from an unauthenticated arbitrary file disclosure vulnerability. Input passed through the logFile GET parameter via the logYumLookup.php script is not properly verified before being used to download log files. This can be exploited to disclose the contents of arbitrary and sensitive files via directory traversal attacks.

Ubuntu Security Notice 7056-1 - Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Masato Kinugawa discovered that Firefox did not properly validate javascript under the "resource://pdf.js" origin. An attacker could potentially exploit this issue to execute arbitrary javascript code and access cross-origin PDF content.

The building management system suffers from an unauthenticated arbitrary file disclosure vulnerability. Input passed through the 'logFile' GET parameter via the 'logYumLookup.php' script is not properly verified before being used to download log files. This can be exploited to disclose the contents of arbitrary and sensitive files via directory traversal attacks.

ABB Cylon Aspect version 3.07.02 suffers from an authenticated arbitrary file disclosure vulnerability. Input passed through the file GET parameter through the downloadDb.php script is not properly verified before being used to download database files. This can be exploited to disclose the contents of arbitrary and sensitive files via directory traversal attacks.
