Online Pizza Ordering v1.0 was discovered to contain an arbitrary file upload vulnerability which allows attackers to execute arbitrary code via a crafted file uploaded to the server.

An "open" Internet faces challenges from autocratic governance models. Policymakers should instead think about creating an Internet that's equitable, inclusive, and secure.

Ubuntu Security Notice 6015-1 - Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. Paul Menzel discovered that Thunderbird did not properly validate OCSP revocation status of recipient certificates when sending S/Mime encrypted email. An attacker could potentially exploits this issue to perform spoofing attack.

Ubuntu Security Notice 6014-1 - Xuewei Feng, Chuanpu Fu, Qi Li, Kun Sun, and Ke Xu discovered that the TCP implementation in the Linux kernel did not properly handle IPID assignment. A remote attacker could use this to cause a denial of service or inject forged data. Ke Sun, Alyssa Milburn, Henrique Kawakami, Emma Benoit, Igor Chervatyuk, Lisa Aichele, and Thais Moreira Hamasaki discovered that the Spectre Variant 2 mitigations for AMD processors on Linux were insufficient in some situations. A local attacker could possibly use this to expose sensitive information.

Ubuntu Security Notice 6008-1 - It was discovered that Exo did not properly sanitized desktop files. A remote attacker could possibly use this issue to to cause a crash or arbitrary code execution.

A novel credential harvester compromises SMTP services to steal data from a range of hosted services and providers, and can also launch SMS-based spam attacks against devices using US mobile carriers.

### Impact The [Livetable Macro](https://extensions.xwiki.org/xwiki/bin/view/Extension/Livetable%20Macro) wasn't properly sanitizing column names, thus allowing the insertion of raw HTML code including JavaScript. This vulnerability was also exploitable via the [Documents Macro](https://extensions.xwiki.org/xwiki/bin/view/Extension/Documents%20Macro) that is included since XWiki 3.5M1 and doesn't require script rights, this can be demonstrated with the syntax `{{documents id="example" count="5" actions="false" columns="doc.title, before<script>alert(1)</script>after"/}}`. Therefore, this can also be exploited by users without script right and in comments. With the interaction of a user with more rights, this could be used to execute arbitrary actions in the wiki, including privilege escalation, remote code execution, information disclosure, modifying or deleting content. ### Patches This has been patched in XWiki 14.9, 14.4.6, and 13.10.10. ### Workarounds It is possible to apply the...

### Impact The [RSS macro](https://extensions.xwiki.org/xwiki/bin/view/Extension/RSS%20Macro) that is bundled in XWiki included the content of the feed items without any cleaning in the HTML output when the parameter `content` was set to `true`. This allowed arbitrary HTML and in particular also JavaScript injection and thus cross-site scripting (XSS) by specifying an RSS feed with malicious content. With the interaction of a user with programming rights, this could be used to execute arbitrary actions in the wiki, including privilege escalation, remote code execution, information disclosure, modifying or deleting content and sabotaging the wiki. The issue can be reproduced by inserting the following XWiki syntax in any wiki page like the user account: ``` {{rss feed="https://xssrss.blogspot.com/feeds/posts/default?alt=rss" content="true" /}} ``` If an alert is displayed when viewing the page, the wiki is vulnerable. ### Patches The issue has been patched in XWiki 14.6 RC1, the con...

### Impact Rights added to a document are not taken into account for viewing it once it's deleted. Note that this vulnerability only impact deleted documents that where containing view rights: the view rights provided on a space of a deleted document are properly checked. ### Patches The problem has been patched in XWiki 14.10 by checking the rights of current user: only admin and deleter of the document are allowed to view it. ### Workarounds There is no workaround for this vulnerability other than upgrading. ### References * Jira ticket: https://jira.xwiki.org/browse/XWIKI-16285 * Commit: https://github.com/xwiki/xwiki-platform/commit/d9e947559077e947315bf700c5703dfc7dd8a8d7 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira](https://jira.xwiki.org) * Email us at [security ML](mailto:[email protected])
