Dell Unity, Dell UnityVSA, and Dell UnityXT versions prior to 5.2.0.0.5.173 contain a Reflected Cross-Site Scripting Vulnerability in Unisphere GUI. An Unauthenticated Remote Attacker could potentially exploit this vulnerability, leading to the execution of malicious HTML or JavaScript code in a victim user's web browser in the context of the vulnerable web application. Exploitation may lead to information disclosure, session theft, or client-side request forgery.

This whitepaper demonstrates leveraging cross site scripting and polyglot exploitation in an exploit called COOLHANDLUKE to violate network segmentation / layer 2 VLAN policies while routing and sending a file between isolated, air gapped networks without a router. This issue affects HPE Procurve, Aruba Networks, Cisco, Dell, and Netgear products.

In this whitepaper, the author demonstrates abusing persistent cross site scripting and polyglot payloads can allow for robust protocol creation similar to COOLHANDLUKE and allows an attacker to exfiltrate, encapsulate, and tunnel their malicious traffic between IPv4 and IPv6 networks without a router. The author calls the technique and protocol "DIRECTIVEFOUR". This issue affects Cisco SMB and Sx Series switches.

A vulnerability was found in Angular up to 11.0.4/11.1.0-next.2. It has been classified as problematic. Affected is the handling of comments. The manipulation leads to cross site scripting. It is possible to launch the attack remotely but it might require an authentication first. Upgrading to version 11.0.5 and 11.1.0-next.3 is able to address this issue. The name of the patch is ba8da742e3b243e8f43d4c63aa842b44e14f2b09. It is recommended to upgrade the affected component.

### Impact If FoF Upload is configured to allow the uploading of SVG files (`image/svg+xml`), navigating directly to an SVG file URI could execute arbitrary Javascript code decided by an attacker. This Javascript code could include the execution of HTTP web requests to Flarum, or any other web service. This could allow data to be leaked by an authenticated Flarum user, or, possibly, for data to be modified maliciously. ### Patches This has been patched with v1.2.3, which now sanitizes uploaded SVG files. ### Workarounds Upgrade to `1.2.3` (requires Flarum 1.2 or later), or remove the ability for users to upload SVG files through FoF Upload. ### References Thank you to Safwat Refaat for the responsible disclosure of this vulnerability.

### Impact We found a possible XSS vector in the `WikiManager.JoinWiki ` wiki page related to the "requestJoin" field. ### Patches The issue is patched in versions 12.10.11, 14.0-rc-1, 13.4.7, 13.10.3. ### Workarounds The easiest workaround is to edit the wiki page `WikiManager.JoinWiki` (with wiki editor) and change the line ``` <input type='hidden' name='requestJoin' value="$!request.requestJoin"/> ``` into ``` <input type='hidden' name='requestJoin' value="$escapetool.xml($!request.requestJoin)"> ``` ### References * https://jira.xwiki.org/browse/XWIKI-19292 * https://github.com/xwiki/xwiki-platform/commit/27f839133d41877e538d35fa88274b50a1c00b9b ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki](https://jira.xwiki.org) * Email us at [security mailing list](mailto:[email protected])

### Impact We found a possible XSS vector in the `FlamingoThemesCode.WebHomeSheet` wiki page related to the "newThemeName" form field. ### Patches The issue is patched in versions 12.10.11, 14.0-rc-1, 13.4.7, 13.10.3. ### Workarounds The easiest workaround is to edit the wiki page `FlamingoThemesCode.WebHomeSheet` (with wiki editor) and change the line ``` <input type="hidden" name="newThemeName" id="newThemeName" value="$request.newThemeName" /> ``` into ``` <input type="hidden" name="newThemeName" id="newThemeName" value="$escapetool.xml($request.newThemeName)" /> ``` ### References * https://jira.xwiki.org/browse/XWIKI-19294 * https://github.com/xwiki/xwiki-platform/commit/bd935320bee3c27cf7548351b1d0f935f116d437 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki](https://jira.xwiki.org) * Email us at [security mailing list](mailto:[email protected])

### Impact Mautic allows you to track open rates by using tracking pixels. The tracking information is stored together with extra metadata of the tracking request. The output isn't sufficiently filtered when showing the metadata of the tracking information, which may lead to a vulnerable situation. ### Patches Please upgrade to 4.3.0 ### Workarounds None. ### References * Internally tracked under MST-38 ### For more information If you have any questions or comments about this advisory: * Email us at [[email protected]](mailto:[email protected])
