XWiki Platform is a generic wiki platform. The rendered diff in XWiki embeds images to be able to compare the contents and not display a difference for an actually unchanged image. For this, XWiki requests all embedded images on the server side. These requests are also sent for images from other domains and include all cookies that were sent in the original request to ensure that images with restricted view right can be compared. Starting in version 11.10.1 and prior to versions 14.10.15, 15.5.1, and 15.6, this allows an attacker to steal login and session cookies that allow impersonating the current user who views the diff. The attack can be triggered with an image that references the rendered diff, thus making it easy to trigger. Apart from stealing login cookies, this also allows server-side request forgery (the result of any successful request is returned in the image's source) and viewing protected content as once a resource is cached, it is returned for all users. As only success...

The XWiki Admin Tools Application provides tools to help the administration of XWiki. Starting in version 4.4 and prior to version 4.5.1, a cross site request forgery vulnerability in the admin tool for executing shell commands on the server allows an attacker to execute arbitrary shell commands by tricking an admin into loading the URL with the shell command. A very simple possibility for an attack are comments. When the attacker can leave a comment on any page in the wiki it is sufficient to include an image with an URL like `/xwiki/bin/view/Admin/RunShellCommand?command=touch%20/tmp/attacked` in the comment. When an admin views the comment, the file `/tmp/attacked` will be created on the server. The output of the command is also vulnerable to XWiki syntax injection which offers a simple way to execute Groovy in the context of the XWiki installation and thus an even easier way to compromise the integrity and confidentiality of the whole XWiki installation. This has been patched by a...

Apache Software Foundation Apache Submarine has a bug when serializing against yaml. The bug is caused by snakeyaml https://nvd.nist.gov/vuln/detail/CVE-2022-1471 . Apache Submarine uses JAXRS to define REST endpoints. In order to handle YAML requests (using application/yaml content-type), it defines a YamlEntityProvider entity provider that will process all incoming YAML requests. In order to unmarshal the request, the readFrom method is invoked, passing the entityStream containing the user-supplied data in `submarine-server/server-core/src/main/java/org/apache/submarine/server/utils/YamlUtils.java`. We have now fixed this issue in the new version by replacing to `jackson-dataformat-yaml`. This issue affects Apache Submarine: from 0.7.0 before 0.8.0. Users are recommended to upgrade to version 0.8.0, which fixes this issue. If using the version smaller than 0.8.0 and not want to upgrade, you can try cherry-pick PR https://github.com/apache/submarine/pull/1054 and rebuild the ...

A cleverly devised username might bypass LDAP authentication checks. In LDAP-authenticated Derby installations, this could let an attacker fill up the disk by creating junk Derby databases. In LDAP-authenticated Derby installations, this could also allow the attacker to execute malware which was visible to and executable by the account which booted the Derby server. In LDAP-protected databases which weren't also protected by SQL GRANT/REVOKE authorization, this vulnerability could also let an attacker view and corrupt sensitive data and run sensitive database functions and procedures. Mitigation: Users should upgrade to Java 21 and Derby 10.17.1.0. Alternatively, users who wish to remain on older Java versions should build their own Derby distribution from one of the release families to which the fix was backported: 10.16, 10.15, and 10.14. Those are the releases which correspond, respectively, with Java LTS versions 17, 11, and 8.

Relative library resolution in linux container-executor binary in Apache Hadoop 3.3.1-3.3.4 on Linux allows local user to gain root privileges. If the YARN cluster is accepting work from remote (authenticated) users, this MAY permit remote users to gain root privileges. Hadoop 3.3.0 updated the " YARN Secure Containers https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/SecureContainer.html " to add a feature for executing user-submitted applications in isolated linux containers. The native binary HADOOP_HOME/bin/container-executor is used to launch these containers; it must be owned by root and have the suid bit set in order for the YARN processes to run the containers as the specific users submitting the jobs. The patch " YARN-10495 https://issues.apache.org/jira/browse/YARN-10495 . make the rpath of container-executor configurable" modified the library loading path for loading .so files from "$ORIGIN/" to ""$ORIGIN/:../lib/native/". This is the a path through which...

Cybersecurity researchers have discovered a stealthy backdoor named Effluence that's deployed following the successful exploitation of a recently disclosed security flaw in Atlassian Confluence Data Center and Server. "The malware acts as a persistent backdoor and is not remediated by applying patches to Confluence," Aon's Stroz Friedberg Incident Response Services said in an analysis published

### Impact XWiki is vulnerable to reflected cross-site scripting (RXSS) via the `rev` parameter that is used in the content of the content menu without escaping. If an attacker can convince a user to visit a link with a crafted parameter, this allows the attacker to execute arbitrary actions in the name of the user, including remote code (Groovy) execution in the case of a user with programming right, compromising the confidentiality, integrity and availability of the whole XWiki installation. The vulnerability can be demonstrated by opening `<xwiki-host>/xwiki/bin/view/Main/?rev=xar%3Aorg.xwiki.platform%3Axwiki-platform-distribution-flavor-common%2F15.5%25%25%22%3e%3cscript%3ealert(1)%3c%2fscript%3e` where `<xwiki-host>` is the URL of your XWiki installation. If an alert is displayed, the installation is vulnerable. ### Patches This has been patched in XWiki 15.6 RC1, 15.5.1 and 14.10.14. ### Workarounds The [patch](https://github.com/xwiki/xwiki-platform/commit/04e325d57d4bcb6ab7...

### Impact XWiki doesn't properly escape the section URL parameter that is used in the code for displaying administration sections. This allows any user with read access to the document `XWiki.AdminSheet` (by default, everyone including unauthenticated users) to execute code including Groovy code. This impacts the confidentiality, integrity and availability of the whole XWiki instance. By opening the URL `<server>/xwiki/bin/get/Main/WebHome?sheet=XWiki.AdminSheet&viewer=content&section=%5D%5D%7B%7B%2Fhtml%7D%7D%7B%7Basync%7D%7D%7B%7Bgroovy%7D%7Dservices.logging.getLogger(%22attacker%22).error(%22Attack%20succeeded!%22)%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D&xpage=view` where `<server>` is the URL of the XWiki installation, it can be tested if an XWiki installation is vulnerable. If this causes a log message `ERROR attacker - Attack succeeded!` to appear in XWiki's log, the installation is vulnerable. In very old versions of XWiki, the attack can be demonstrated...

### Impact In XWiki Platform, it's possible for a user to write a script in which any velocity content is executed with the right of any other document content author. To reproduce: As a user with script but not programming right, create a document with the following content: ``` {{velocity}} #set($main = $xwiki.getDocument('AppWithinMinutes.DynamicMessageTool')) $main.setTitle('$doc.getDocument().getContentAuthor()') $main.getPlainTitle() {{/velocity}} ``` Since this API require programming right and the user does not have it, the expected result is `$doc.document.authors.contentAuthor` (not executed script), unfortunately with the security vulnerability we get `XWiki.superadmin` which shows that the title was executed with the right of the unmodified document. ### Patches This has been patched in XWiki 14.10.7 and 15.2-RC-1. ### Workarounds There are no known workarounds for it. ### References * https://jira.xwiki.org/browse/XWIKI-20624 * https://github.com/xwiki/xwiki-pla...
