#vulnerability
A list of topics we covered in the week of October 28 to November 3 of 2024
A vulnerability was found in Umbraco CMS 12.3.6. It has been classified as problematic. Affected is an unknown function of the file /Umbraco/preview/frame?id{} of the component Dashboard. The manipulation of the argument culture leads to cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.
Plus: Cops take down a notorious infostealer, Strava leaks world leaders’ locations, and a hacking scandal is causing chaos in Italy.
### Summary When a WebDriver is used to fetch files source:file:///etc/passwd can be used to retrieve local system files, where the more traditional file:///etc/passwd gets blocked ### Details The root cause is the payload source:file:///etc/passwdpasses the regex [here](https://github.com/dgtlmoon/changedetection.io/blob/master/changedetectionio/model/Watch.py#L19) and also passes the check [here](https://github.com/dgtlmoon/changedetection.io/blob/master/changedetectionio/processors/__init__.py#L35) where a traditional file:///etc/passwd would get blocked ### PoC [CL-ChangeDetection.io Path Travsersal-311024-181039.pdf](https://github.com/user-attachments/files/17591630/CL-ChangeDetection.io.Path.Travsersal-311024-181039.pdf) ### Impact It depends on where the webdriver is deployed but generally this is a high impact vulnerability
### Summary By default `oak` does not allow transferring of hidden files with `Context.send` API. However, this can be bypassed by encoding `/` as its URL encoded form `%2F`. ### Details 1.) Oak uses [decodeComponent](https://github.com/oakserver/oak/blob/3896fe568b25ac0b4c5afbf822ff8344c3d1712a/send.ts#L182C10-L182C25) which seems to be unexpected. This is also the reason why it is not possible to access a file that contains URL encoded characters unless the client URL encodes it first. 2.) The function [isHidden](https://github.com/oakserver/oak/blob/3896fe568b25ac0b4c5afbf822ff8344c3d1712a/send.ts#L117-L125) is flawed since it only checks if the first subpath is hidden, allowing secrets to be read from `subdir/.env`. ### PoC ```ts // server.ts import { Application } from "jsr:@oak/[email protected]"; const app = new Application(); app.use(async (context, next) => { try { await context.send({ root: './root', hidden: false, // default }); } catch { await ...
The Recall AI tool will be available to Copilot+ PC subscribers in December, and can be used to record images of every interaction on the device for review later. Critics say this introduces major privacy and security concerns along with useful functionality.
OWASP has released guidance materials addressing how to respond to deepfakes, AI security best practices, and how to secure open source and commercial generative AI applications.
