Red Hat Security Advisory 2023-3423-01 - The cups-filters package contains back ends, filters, and other software that was once part of the core Common UNIX Printing System distribution but is now maintained independently. Issues addressed include a code execution vulnerability.
### Summary Some avo fields are vulnerable to XSS when rendering html based content. ### Details During the analysis of the web application, a rendered field was discovered that did not filter JS / HTML tags in a safe way and can be abused to execute js code on a client side. The trix field uses the trix editor in the backend to edit rich text data which basically operates with html tags. To display the stored data in a rendered view, the HasHTMLAttributes concern is used. This can be exploited by an attacker to store javascript code in any trix field by intercepting the request and modifying the post data, as the trix editor does not allow adding custom html or js tags on the frontend. ### PoC  _Adding javascript in the post request which is used when editing a "post" resource (body is declared as a trix field)_  base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).

### Summary Vite Server Options (`server.fs.deny`) can be bypassed using double forward-slash (//) allows any unauthenticated user to read file from the Vite root-path of the application including the default [`fs.deny` settings](https://vitejs.dev/config/server-options.html#server-fs-deny) (`['.env', '.env.*', '*.{crt,pem}']`) ### Impact Only users explicitly exposing the Vite dev server to the network (using `--host` or [`server.host` config option](https://vitejs.dev/config/server-options.html#server-host)) are affected, and only files in the immediate Vite project root folder could be exposed. ### Patches Fixed in [email protected], [email protected], [email protected], [email protected] And in the latest minors of the previous two majors: [email protected], [email protected] ### Details Vite serve the application with under the root-path of the project while running on the dev mode. By default, vite using server options fs.deny to protected the sensitive information of the file. But, with simply double forward-slash, ...
### Impact An attacker could crash the server by sending malformed JWT JSON in `LoginPacket` due to a security vulnerability in [`netresearch/jsonmapper`](https://github.com/cweiske/JsonMapper), due to improper checking for mapping JSON arrays and objects onto scalar model properties such as strings. ### Patches The problem was fixed in a fork of JsonMapper in dktapps/JsonMapper@a31902a31f5b6fdb832f57c0e3a3f16a3b41c012. PocketMine-MP releases 4.20.5 and 4.21.1 have been released with the fix. ### Workarounds - Users of PocketMine-MP source installations may manually install the patched version of JsonMapper by backporting commit pmmp/PocketMine-MP@09668a37d66c6023685a948b7550c918620e98f2. - A plugin may also be able to workaround this issue by using `DataPacketReceiveEvent` to attempt detection of suspicious payloads. An `ErrorException` will be thrown in the crash case, which can be caught by plugins. ### References cweiske/jsonmapper#210
### Impact #### Description: JStachio fails to escape single quotes `'` in HTML, allowing an attacker to inject malicious code. #### Reproduction Steps: Use the following template code: ```html <div attr='{{value}}'></div> ``` Set the value variable to `' onblur='alert(1)`. ```java public class Escaping { public static void main(String[] args) { Model model = new Model("' onblur='alert(1)"); String result = AttributeTemplate.of().execute(model); System.out.println(result); } @JStache(template = "<div attr='{{value}}'></div>", name="AttributeTemplate") @JStacheConfig(contentType= Html.class) public static class Model { public final String value; public Model(String value) { this.value = value; } public String getValue() { return value; } } } ``` Expected Result: The resulting output should have properly escaped the single quotes and not execute the inject...
Minical 1.0.0 and earlier contains a CSV injection vulnerability which allows an attacker to execute remote code. The vulnerability exists due to insufficient input validation on the Customer Name field in the Accounting module that is used to construct a CSV file.
