Alert: PoC Exploits Released for Citrix and VMware Vulnerabilities

Alert: PoC Exploits Released for Citrix and VMware Vulnerabilities
Oct 25, 2023 Exploit / Vulnerability
Virtualization services provider VMware has alerted customers to the existence of a proof-of-concept (PoC) exploit for a recently patched security flaw in Aria Operations for Logs. Tracked as CVE-2023-34051 (CVSS score: 8.1), the high-severity vulnerability relates to a case of authentication bypass that could lead to remote code execution. "An unauthenticated, malicious actor can inject files into the operating system of an impacted appliance which can result in remote code execution," VMware  noted  in an advisory on October 19, 2023. James Horseman from Horizon3.ai and the Randori Attack Team have been credited with discovering and reporting the flaw. Horizon3.ai has since made available a  PoC for the vulnerability , prompting VMware to revise its advisory this week. It's worth noting that CVE-2023-34051 is a patch bypass for a  set of critical flaws  that were addressed by VMware earlier this January that could expose users to remote code execution attacks. &

PoC Exploits Released for Citrix ADC and Gateway RCE Vulnerability

PoC Exploits Released for Citrix ADC and Gateway RCE Vulnerability
Jan 11, 2020
It's now or never to prevent your enterprise servers running vulnerable versions of Citrix application delivery, load balancing, and Gateway solutions from getting hacked by remote attackers. Why the urgency? Earlier today, multiple groups publicly released weaponized proof-of-concept exploit code [ 1 , 2 ] for a recently disclosed remote code execution vulnerability in Citrix's NetScaler ADC and Gateway products that could allow anyone to leverage them to take full control over potential enterprise targets. Just before the last Christmas and year-end holidays, Citrix announced that its Citrix Application Delivery Controller (ADC) and Citrix Gateway are vulnerable to a critical path traversal flaw (CVE-2019-19781) that could allow an unauthenticated attacker to perform arbitrary code execution on vulnerable servers. Citrix confirmed that the flaw affects all supported version of the software, including: Citrix ADC and Citrix Gateway version 13.0 all supported build

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Making Sense of Operational Technology Attacks: The Past, Present, and Future
Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.

Hackers Have Started Exploiting Drupal RCE Exploit Released Yesterday

Hackers Have Started Exploiting Drupal RCE Exploit Released Yesterday
Apr 14, 2018
Hackers have started exploiting a recently disclosed critical vulnerability in Drupal shortly after the public release of working exploit code. Two weeks ago, Drupal security team discovered a highly critical remote code execution vulnerability, dubbed Drupalgeddon2 , in its content management system software that could allow attackers to completely take over vulnerable websites. To address this vulnerability the company immediately released updated versions of Drupal CMS without releasing any technical details of the vulnerability, giving more than a million sites enough time to patch the issue. Two days ago, security researchers at Check Point and Dofinity published complete technical details about this vulnerability (CVE-2018-7600), using which, a Russian security researcher published a proof-of-concept (PoC) exploit code for Drupalgeddon2 on GitHub. The Drupalgeddon2 vulnerability that affects all versions of Drupal from 6 to 8 allows an unauthenticated, remote attack

iPhone Instagram users vulnerable to hackers
Dec 03, 2012
Instagram - Facebook's popular photo sharing app for iOS, is currently has a vulnerability that could make your account susceptible to hackers. A security researcher Carlos Reventlov  published on Friday another attack on Facebook's Instagram photo-sharing service that could allow a hacker to seize control of a victim's account. " The Instagram app communicates with the Instagram API via HTTP and HTTPs connections. Highly sensitive activities, such as login and editing profile data, are sent through a secure channel. However, some other request are sent through plain HTTP without a signature, those request could be exploited by an attacker connected to the same LAN of the victim's iPhone. " Vulnerability Details --   The vulnerability is in the 3.1.2 version of Instagram's application, which is  susceptible to "eavesdropping and man in the middle attacks that could lead an evil user to delete photos and download private media without the victim's con

Remote 0day Exploit for Tectia SSH Server released

Remote 0day Exploit for Tectia SSH Server released
Dec 03, 2012
Hacker @kingcope discovered critical vulnerability in Tectia SSH Server. Exploit working on SSH-2.0-6.1.9.95 SSH Tectia Server (Latest available version from www.tectia.com) that allow attacker to bypass Authentication remotely. Description :  An attacker in the possession of a valid username of an SSH Tectia installation running on UNIX (verified on AIX/Linux) can login without a password. The bug is in the "SSH USERAUTH CHANGE REQUEST" routines which are there to allow a user to change their password. A bug in the code allows an attacker to login without a password by forcing a password change request prior to authentication. Download Exploit Code : Click Here A default installation on Linux (version 6.1.9.95 of Tectia) is vulnerable to the attack. Eric Romang posted a Demo video on Youtube, hope you will like it :) Command Source : https://goo.gl/BHqWd
