### 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 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 A logged-in user with any role can delete arbitrary files on the filesystem by calling the `sync/clean_sync_dir` endpoint. The `dir_name` POST parameter is not validated/sanitized and is used to construct the `syncDir` that is deleted by calling `fs.rm`. ### Details - file: https://github.com/saltcorn/saltcorn/blob/v1.0.0-beta.15/packages/server/routes/sync.js#L337-L346 ```js router.post( "/clean_sync_dir", error_catcher(async (req, res) => { const { dir_name } = req.body; // [1] source try { const rootFolder = await File.rootFolder(); const syncDir = path.join( rootFolder.location, "mobile_app", "sync", dir_name // [2] ); await fs.rm(syncDir, { recursive: true, force: true }); // [3] sink res.status(200).send(""); } catch (error) { getState().log(2, `POST /sync/clean_sync_dir: '${error.message}'`); res.status(400).json({ error: error.message || error }); } }) ); ``` ### Po...

# Summary If values passed to a paragraph widget are not valid and contain a specific set of characters, applications are vulnerable to XSS attack against a user who opens a page on which a paragraph widget is rendered. Versions of dynamic dashboard from v3.0.0 through v3.0.2 are affected. Please upgrade to dynamic dashboard [v3.0.2](https://github.com/lara-zeus/dynamic-dashboard/releases/tag/v3.0.2). # PoC >PoC will be published in a few weeks, once developers have had a chance to upgrade their apps. # Response This vulnerability (in paragraph widget only) was reported by **Raghav Sharma**, who reported the issue and patched the issue during the morning of 05/10/2024. Thank you **Raghav Sharma**. The review process concluded the same day at night, which revealed the issue was also present in paragraph widget. This was fixed the same day and dynamic dashboard [v3.0.2](https://github.com/lara-zeus/dynamic-dashboard/releases/tag/v3.0.2) followed. ## Note: if you're published the vi...

### 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.

Organizations are losing between $94 - $186 billion annually to vulnerable or insecure APIs (Application Programming Interfaces) and automated abuse by bots. That’s according to The Economic Impact of API and Bot Attacks report from Imperva, a Thales company. The report highlights that these security threats account for up to 11.8% of global cyber events and losses, emphasizing the escalating

The interest in passwordless authentication has increased due to the rise of hybrid work environments and widespread digitization. This has led to a greater need for reliable data security and user-friendly interfaces. Without these measures, organizations are at risk of experiencing data breaches, leaks, and significant financial losses.  While traditional password-based systems offer
