Vulnerabilities

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. By either creating a new or editing an existing document with an icon set, an attacker can inject XWiki syntax and Velocity code that is executed with programming rights and thus allows remote code execution. There are different attack vectors, the simplest is the Velocity code in the icon set&amp;#39;s HTML or XWiki syntax definition. The [icon picker](https://extensions.xwiki.org/xwiki/bin/view/Extension/Icon%20Theme%20Application#HIconPicker) can be used to trigger the rendering of any icon set. The XWiki syntax variant of the icon set is also used without any escaping in some documents, allowing to inject XWiki syntax including script macros into a document that might have programming right, for this the currently used icon theme needs to be edited. Further, the HTML output of the icon set is output as JSON in the icon picker and this JSON is interpreted as XWiki syntax, allowing again the injection of script macros into a document with programming right and thus allowing remote code execution. This impacts the confidentiality, integrity and availability of the whole XWiki instance. This issue has been patched in XWiki 14.10.6 and 15.1. Icon themes now require script right and the code in the icon theme is executed within the context of the icon theme, preventing any rights escalation. A macro for displaying icons has been introduced to avoid injecting the raw wiki syntax of an icon set into another document. Users are advised to upgrade. There are no known workarounds for this vulnerability.<br />

The affected TBox RTUs are missing authorization for running some API commands. An attacker running these commands could reveal sensitive information such as software versions and web server file contents.<br /> <br />

A vulnerability was found in SimplePHPscripts Classified Ads Script 1.8. It has been classified as problematic. Affected is an unknown function of the file /preview.php of the component URL Parameter Handler. The manipulation of the argument p leads to cross site scripting. It is possible to launch the attack remotely. It is recommended to upgrade the affected component. VDB-232710 is the identifier assigned to this vulnerability.

Xwiki commons is the common modules used by other XWiki top level projects. The HTML sanitizer that is included in XWiki since version 14.6RC1 allowed form and input HTML tags. In the context of XWiki, this allows an attacker without script right to either create forms that can be used for phishing attacks or also in the context of a sheet, the attacker could add an input like `{{html}}{{/html}}` that would allow remote code execution when it is submitted by an admin (the sheet is rendered as part of the edit form). The attacker would need to ensure that the edit form looks plausible, though, which can be non-trivial as without script right the attacker cannot display the regular content of the document. This has been patched in XWiki 14.10.6 and 15.2RC1 by removing the central form-related tags from the list of allowed tags. Users are advised to upgrade. As a workaround an admin can manually disallow the tags by adding `form, input, select, textarea, button` to the configuration option `xml.htmlElementSanitizer.forbidTags` in the `xwiki.properties` configuration file.

An issue was discovered in Weblib Ucopia before 6.0.13. OS Command Injection injection can occur, related to chroot.

Tuleap is a Free &amp; Open Source Suite to improve management of software developments and collaboration. When switching from a project visibility that allows restricted users to `Private without restricted`, restricted users that are project administrators keep this access right. Restricted users that were project administrators before the visibility switch keep the possibility to access the project and do some administration actions. This issue has been resolved in Tuleap version 14.9.99.63. Users are advised to upgrade. There are no known workarounds for this issue.

An issue was discovered in Weblib Ucopia before 6.0.13. The SSH Server has Insecure Permissions.

libtiff 4.5.0 is vulnerable to Buffer Overflow via /libtiff/tools/tiffcrop.c:8499. Incorrect updating of buffer size after rotateImage() in tiffcrop cause heap-buffer-overflow and SEGV.

libtiff 4.5.0 is vulnerable to Buffer Overflow in uv_encode() when libtiff reads a corrupted little-endian TIFF file and specifies the output to be big-endian.

ILIAS 7.21 and 8.0_beta1 through 8.2 is vulnerable to reflected Cross-Site Scripting (XSS).

A security defect was identified in Foundry workspace-server that enabled a user to bypass an authorization check and view settings related to &amp;#39;Developer Mode&amp;#39;. This enabled users with insufficient privilege the ability to view and interact with Developer Mode settings in a limited capacity. A fix was deployed with workspace-server 7.7.0.

A security defect was identified in Foundry Issues. If a user was added to an issue on a resource that they did not have access to and consequently could not see, they could query Foundry&amp;#39;s Notification API and receive metadata about the issue including the RID of the issue, severity, internal UUID of the author, and the user-defined title of the issue.
