### Impact Private messages or posts might be leaked to third parties if victim opens the attackers site while browsing nodebb. ### Patches * Patched in v3.1.3 * Backported to v2.x line via v2.8.13 ### Workarounds Users can cherry-pick https://github.com/NodeBB/NodeBB/commit/51096ad2345fb1d1380bec0a447113489ef6c359 if they are on v3.x If you are running v2.x of NodeBB, you can cherry-pick a5d92da9ddac5607ab7f737520a66eaed6d3ddee followed by 62e162cf1e735e42462be1db9b4954b5a69accdf

### Summary The application contains a reflected cross-site scripting via URL-parameter `?k304=...` and `?setck=...` ### Details A reflected cross-site scripting (XSS) vulnerability exists in the web interface of the application that could allow an attacker to execute malicious javascript code by tricking users into accessing a malicious link. The worst-case outcome of this is being able to move or delete existing files on the server, or upload new files, using the account of the person who clicks the malicious link. It is recommended to change the passwords of your copyparty accounts, unless you have inspected your logs and found no trace of attacks. ### Checking for exposure if copyparty is running behind a reverse proxy, you can check the access-logs for traces of attacks, by grepping for URLs containing `?hc=` with `<` somewhere in its value, for example using the following command: * nginx: ```bash (gzip -dc access.log*.gz; cat access.log) | sed -r 's/" [0-9]+ .*//' | grep...

### Impact Authenticated users can inject malicious code in widgets with units, which is then executed both in the element preview (back end) and on the website (front end). ### Patches Update to Contao 4.9.42, 4.13.28 or 5.1.10. ### Workarounds Disable login for all untrusted back end users. ### References https://contao.org/en/security-advisories/cross-site-scripting-in-widgets-with-units ### For more information If you have any questions or comments about this advisory, open an issue in [contao/contao](https://github.com/contao/contao/issues/new/choose). ### Credits Thanks to Maximilian Seilmaier from usd AG for reporting this vulnerability.

An improper neutralization of input during web page generation ('Cross-site Scripting') [CWE-79] vulnerability in Apache Felix Healthcheck Webconsole Plugin version 2.0.2 and prior may allow an attacker to perform a reflected cross-site scripting (XSS) attack. Upgrade to Apache Felix Healthcheck Webconsole Plugin 2.1.0 or higher.

Java object deserialization issue in Jackrabbit webapp/standalone on all platforms allows attacker to remotely execute code via RMIVersions up to (including) 2.20.10 (stable branch) and 2.21.17 (unstable branch) use the component "commons-beanutils", which contains a class that can be used for remote code execution over RMI. Users are advised to immediately update to versions 2.20.11 or 2.21.18. Note that earlier stable branches (1.0.x .. 2.18.x) have been EOLd already and do not receive updates anymore. In general, RMI support can expose vulnerabilities by the mere presence of an exploitable class on the classpath. Even if Jackrabbit itself does not contain any code known to be exploitable anymore, adding other components to your server can expose the same type of problem. We therefore recommend to disable RMI access altogether (see further below), and will discuss deprecating RMI support in future Jackrabbit releases. How to check whether RMI support is enabledRMI support can be o...

North Korean nation-state actors affiliated with the Reconnaissance General Bureau (RGB) have been attributed to the JumpCloud hack following an operational security (OPSEC) blunder that exposed their actual IP address. Google-owned threat intelligence firm Mandiant attributed the activity to a threat actor it tracks under the name UNC4899, which likely shares overlaps with clusters already

Ubuntu Security Notice 6243-1 - It was discovered that Graphite-Web incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to perform server-side request forgery and obtain sensitive information. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. It was discovered that Graphite-Web incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to perform cross site scripting and obtain sensitive information.

WordPress File Manager Advanced Shortcode plugin does not adequately prevent uploading files with disallowed MIME types when using the shortcode. This leads to remote code execution in cases where the allowed MIME type list does not include PHP files. In the worst case, this is available to unauthenticated users, but it also works in an authenticated configuration. Versions 2.3.2 and below are affected. To install the Shortcode plugin File Manager Advanced version 5.0.5 or lower is required to keep the configuration vulnerable. Any user privileges can exploit this vulnerability which results in access to the underlying operating system with the same privileges under which the Wordpress web services run.
