exec.CommandContext in Chaosblade 0.3 through 1.7.3, when server mode is used, allows OS command execution via the cmd parameter without authentication.

Hackers sent a convincing lure document, but after 20 years of similar attacks, the target organization was well prepared.

A vulnerability has been discovered and fixed in Mesop that could potentially allow unauthorized access to files on the server hosting the Mesop application. The vulnerability was related to insufficient input validation in a specific endpoint. This could have allowed an attacker to access files not intended to be served. Users are strongly advised to update to the latest version of Mesop immediately. The latest version includes a fix for this vulnerability. We would like to thank @Letm3through for reporting this issue and proposing mitigations to address this issue.

### Impact If you're relying on blocking access to localhost using the default `0.0.0.0` filter this can be bypassed using other registered loopback devices (like `127.0.0.2` - `127.127.127.127`) ### Workaround You can block this bypass by manually adding the `127.0.0.0/8` CIDR range which will block access to any `127.X.X.X` ip instead of just `127.0.0.1`.

Scammers are creating fake Walmart virtual shopping lists that look like a contact page for customer service.

### Impact A bad regular expression is generated any time you have two parameters within a single segment, when adding a `-` at the end, like `/:a-:b-`. ### Patches Update to find-my-way v8.2.2 or v9.0.1. or subsequent versions. ### Workarounds No known workarounds. ### References - [CVE-2024-45296](https://github.com/advisories/GHSA-9wv6-86v2-598j) - [Detailed blog post about `path-to-regexp` vulnerability](https://blakeembrey.com/posts/2024-09-web-redos/)

A stored cross-site scripting has been found in the image upload functionality that can be used by normal registered users: It is possible to upload a SVG image containing JavaScript and it's also possible to upload a HTML document when the format parameter is manually changed to [documents](https://github.com/owen2345/camaleon-cms/blob/feccb96e542319ed608acd3a16fa5d92f13ede67/app/uploaders/camaleon_cms_uploader.rb#L105-L106) or a string of an [unsupported format](https://github.com/owen2345/camaleon-cms/blob/feccb96e542319ed608acd3a16fa5d92f13ede67/app/uploaders/camaleon_cms_uploader.rb#L110-L111). If an authenticated user or administrator visits that uploaded image or document malicious JavaScript can be executed on their behalf (e.g. changing or deleting content inside of the CMS.) Proof of concept Login as a normal user (if user signup is enabled). Go to the user's profile. And upload the following profile picture via drag and drop. The content of the SVG file could be as follows ...

A path traversal vulnerability accessible via MediaController's download_private_file method allows authenticated users to download any file on the web server Camaleon CMS is running on (depending on the file permissions). In the [download_private_file](https://github.com/owen2345/camaleon-cms/blob/feccb96e542319ed608acd3a16fa5d92f13ede67/app/controllers/camaleon_cms/admin/media_controller.rb#L28) method: ```ruby def download_private_file cama_uploader.enable_private_mode! file = cama_uploader.fetch_file("private/#{params[:file]}") send_file file, disposition: 'inline' end ``` The file parameter is passed to the [fetch_file](https://github.com/owen2345/camaleon-cms/blob/feccb96e542319ed608acd3a16fa5d92f13ede67/app/uploaders/camaleon_cms_local_uploader.rb#L27) method of the CamaleonCmsLocalUploader class (when files are uploaded locally): ```ruby def fetch_file(file_name) raise ActionController::RoutingError, 'File not found' unless file_exists?(file_name) file_name end ``...
