### Summary It's possible for an attacker to construct an XLSX file that links images from arbitrary paths. When embedding images has been enabled in HTML writer with `$writer->setEmbedImages(true);` those files will be included in the output as `data:` URLs, regardless of the file's type. Also URLs can be used for embedding, resulting in a Server-Side Request Forgery vulnerability. ### Details XLSX files allow embedding or linking media. When In `xl/drawings/drawing1.xml` an attacker can do e.g.: ```xml <a:blip cstate="print" r:link="rId1" /> ``` And then, in `xl/drawings/_rels/drawing1.xml.rels` they can set the path to anything, such as: ```xml <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="/etc/passwd" /> ``` or ```xml <Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="http://example.org" /> ``` When the HTML writer is outputting the...

### Summary It's possible for an attacker to construct an XLSX file which links media from external URLs. When opening the XLSX file, PhpSpreadsheet retrieves the image size and type by reading the file contents, if the provided path is a URL. By using specially crafted `php://filter` URLs an attacker can leak the contents of any file or URL. Note that this vulnerability is different from [GHSA-w9xv-qf98-ccq4](https://github.com/PHPOffice/PhpSpreadsheet/security/advisories/GHSA-w9xv-qf98-ccq4), and resides in a different component. ### Details When an XLSX file is opened, the XLSX reader calls `setPath()` with the path provided in the `xl/drawings/_rels/drawing1.xml.rels` file in the XLSX archive: ```php if (isset($images[$embedImageKey])) { // ...omit irrelevant code... } else { $linkImageKey = (string) self::getArrayItem( $blip->attributes('http://schemas.openxmlformats.org/officeDocument/2006/relationships'), 'link' ); if (isset($images[$linkImag...

### 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...

ABB Cylon Aspect versions 3.08.00 and below suffer from an authenticated OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the SYSLOG HTTP POST parameter called by the syslogSwitch.php script.

ABB Cylon Aspect versions 3.08.01 and below suffer from an unauthenticated OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the Footer HTTP POST parameter called by the caldavUtil.php script.

ABB Cylon Aspect versions 3.08.00 and below suffer from an authenticated OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the timeserver HTTP POST parameter called by the setTimeServer.php script.

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.
