The Artica Proxy administrative web application will deserialize arbitrary PHP objects supplied by unauthenticated users and subsequently enable code execution as the www-data user. Version 4.50 is affected.

Artica Proxy versions 4.40 and 4.50 suffer from a local file inclusion protection bypass vulnerability that allows for path traversal.

Ubuntu Security Notice 6649-2 - USN-6649-1 fixed vulnerabilities in Firefox. The update introduced several minor regressions. This update fixes the problem. Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Alfred Peters discovered that Firefox did not properly manage memory when storing and re-accessing data on a networking channel. An attacker could potentially exploit this issue to cause a denial of service. Johan Carlsson discovered that Firefox incorrectly handled Set-Cookie response headers in multipart HTTP responses. An attacker could potentially exploit this issue to inject arbitrary cookie values. Gary Kwong discovered that Firefox incorrectly generated codes on 32-bit ARM devices, which could lead to unexpected numeric conversions or undefined behaviour. An attacke...

Red Hat Security Advisory 2024-1153-03 - An update for squid is now available for Red Hat Enterprise Linux 9.0 Extended Update Support. Issues addressed include buffer over-read, denial of service, and null pointer vulnerabilities.

### Summary Use of inherently unsafe `*const c_void` and `ExternalPointer` leads to use-after-free access of the underlying structure, resulting in arbitrary code execution. ### Details `*const c_void` and `ExternalPointer` (defined via `external!()` macros) types are used to represent `v8::External` wrapping arbitrary `void*` with an external lifetime. This is inherently unsafe as we are effectively eliding all Rust lifetime safety guarantees. `*const c_void` is trivially unsafe. `ExternalPointer` attempts to resolve this issue by wrapping the underlying pointer with a `usize`d marker ([`ExternalWithMarker<T>`](https://github.com/denoland/deno_core/blob/a2838062a8f51926140a48a8aa926330c6f9070c/core/external.rs#L49)). However, the marker [relies on the randomness of PIE address (binary base address)](https://github.com/denoland/deno_core/blob/a2838062a8f51926140a48a8aa926330c6f9070c/core/external.rs#L10) which is still trivially exploitable for a non-PIE binary. It is also equall...

### Summary Use of raw file descriptors in `op_node_ipc_pipe()` leads to premature close of arbitrary file descriptors, allowing standard input to be re-opened as a different resource resulting in permission prompt bypass. ### Details Node child_process IPC relies on the JS side to pass the raw IPC file descriptor to `op_node_ipc_pipe()`, which returns a `IpcJsonStreamResource` ID associated with the file descriptor. On closing the resource, the raw file descriptor is closed together. Although closing a file descriptor is seemingly a harmless task, this has been known to be exploitable: - With `--allow-read` and `--allow-write` permissions, one can open `/dev/ptmx` as stdin. This device happily accepts TTY ioctls and pipes anything written into it back to the reader. - This has been presented in a hacking competition (WACON 2023 Quals "dino jail"). - However, the precondition of this challenge was heavily contrived: fd 0 has manually been closed by FFI and `setuid()` was used...

The ALPHV gang's attempt to cover up an exit scam isn't going well.

### Summary Edit configuration file API in dashboard component of ESPHome version 2023.12.9 (command line installation and Home Assistant add-on) serves unsanitized data with “Content-Type: text/html; charset=UTF-8”, allowing remote authenticated user to inject arbitrary web script and exfiltrate session cookies via Cross-Site scripting (XSS). ### Credits Spike Reply Cybersecurity Teams ### Details It is possible for a malicious authenticated user to inject arbitrary Javascript in configuration files using a POST request to the /edit endpoint, the configuration parameter allows to specify the file to write. To trigger the XSS vulnerability, the victim must visit the page /edit?configuration=[xss file]. ### PoC To reproduce the issue, it is possible to perform a POST request to inject the payload: request: POST /edit?configuration=xss.yaml HTTP/1.1 Host: localhost:6052 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/116.0 Accept: */* Accept-Language: ...

### Summary Here it is observed that the CasaOS doesn't defend against password brute force attacks, which leads to having full access to the server. ### Details The web application lacks control over the login attempts i.e. why attacker can use a password brute force attack to find and get full access over the. ### PoC 1. Capture login request in proxy tool like Burp Suite and select password field.  2. Here I have started attack with total number of 271 password tries where the last one is the correct password and as we can see in the following image we get a **400 Bad Request** status code with the message "**Invalid Password**" and response length **769** on 1st request which was sent at **_Tue, 16 Jan 2024 18:31:32 GMT_**  **Note**: _We have tested this vulnerabil...
