Watch Out IT Admins! Two Unpatched Critical RCE Flaws Disclosed in rConfig

rConfig network configuration management vulnerability

If you’re using the popular rConfig network configuration management utility to protect and manage your network devices, here we have an important and urgent warning for you.

A cybersecurity researcher has recently published details and proof-of-concept exploits for two unpatched, critical remote code execution vulnerabilities in the rConfig utility, at least one of which could allow unauthenticated remote attackers to compromise targeted servers.

Written in native PHP, rConfig is a free, open source network device configuration management utility that allows network engineers to configure and take frequent configuration snapshots of their network devices.

According to the project website, rConfig is being used to manage more than 3.3 million network devices, including switches, routers, firewalls, load-balancer, WAN optimizers.

What’s more worrisome? Both vulnerabilities affect all versions of rConfig, including the latest rConfig version 3.9.2, with no security patch available at the time of writing.

Discovered by Mohammad Askar, each flaw resides in a separate file of rConfig—one, tracked as CVE-2019-16662, can be exploited remotely without requiring pre-authentication, while the other, tracked as CVE-2019-16663, requires authentication before its exploitation.

  • Unauthenticated RCE (CVE-2019-16662) in ajaxServerSettingsChk.php
  • Authenticated RCE (CVE-2019-16663) in search.crud.php

In both cases, to exploit the flaw, all an attacker needs to do is access the vulnerable files with a malformed GET parameter designed to execute malicious OS commands on the targeted server.

As shown in the screenshots shared by the researcher, the PoC exploits allow attackers to get a remote shell from the victim’s server, enabling them to run any arbitrary command on the compromised server with the same privileges as of the web application.

Meanwhile, another independent security researcher analysed the flaws and discovered that the second RCE vulnerability could also be exploited without requiring authentication in rConfig versions prior to version 3.6.0.

“After reviewing rConfig’s source code, however, I found out that not only rConfig 3.9.2 has those vulnerabilities but also all versions of it. Furthermore, CVE-2019-16663, the post-auth RCE can be exploited without authentication for all versions before rConfig 3.6.0,” said the researcher, who goes by online alias Sudoka.

Askar responsibly reported both vulnerabilities to the rConfig project maintainers almost a month back and then recently decided to release details and PoC publicly after the maintainers failed to acknowledge or respond to his findings.

If you are using rConfig, you are recommended to temporarily remove it from your server until security patches arrive.

15-year-old Unpatched Root Access Bug found in Apple’s macOS

Source: National Cyber Security – Produced By Gregory Evans

After a disastrous 2017, where Apple faced all sorts of security-related issues and complaints, the company is in trouble again right from the first day of the New Year! On the very first day of 2018 (or the last day of 2017, depending on your location and region), a security researcher having immense expertise in hacking Apple’s iOS has posted details of an unpatched security flaw present in macOS operating system.

“One tiny, ugly bug. Fifteen years. Full system compromise” wrote the researcher, who uses the alias Siguza (s1guza).

The researcher stated that the flaw can be exploited by cyber-crooks to gain full control of the computer. The unpatched zero-day vulnerability is claimed to be 15 years old. The researcher has also posted a proof-of-concept exploit code, which can be reviewed on GitHub.

Siguza, who also calls himself Hobbyist Hacker, noted that this is a dangerous local privilege escalation (LPE) flaw, which allows anyone (even an unprivileged attacker) to obtain root access on the targeted computer so as to execute malicious code. This LPE flaw affects the kernel extension IOHIDFamily, which was designed for HID (human interface device) like touchscreen or buttons.

Furthermore, the malware that has been designed to exploit this 0-day vulnerability can install itself deep into the system and cybercriminals can target Apple’s critical security programs like the System Integrity Protection (SIP) and Apple Mobile File Integrity (AMFI).

In order to successfully carry out the exploitation of the system, cybercriminals need to get users logged out from the system, which is likely to alert most of the users. However, to evade detection, cybercriminals can attack when the system is shut down or restarted.

The flaw was discovered when Siguza was trying to identify flaws that would allow him to hack the iOS kernel. While doing so Siguze noticed that some of the extension’s components including the IOHIDSystem existed solely on macOS. This discovery led to the identification of the critical zero-day vulnerability in the operating system. Siguza wrote in his post:

“Needs to be running on the host already (nothing remote), achieves full system compromise by itself, but logs you out in the process.”

“Can wait for logout though and is fast enough to run on shutdown/reboot until 10.13.1. On 10.13.2 it takes a fair bit longer (maybe half a minute) after logging out, so if your OS logs you out unexpectedly… maybe pull the plug?” explained Siguza.

The vulnerability is found only in macOS and not in other Apple products such as the iOS but it affects all versions of macOS. Although the flaw is not too serious and concerning it does show that Apple needs to enhance the security of its software. The proof-of-concept created by Siguza is applicable on macOS High Sierra 10.13.1 and earlier versions but he believes that the exploit can be tweaked to become effective on a new version of macOS 10.13.2 released on Dec 6.

Siguza further added that the reason why he publicly announced his findings instead of informing Apple secretly is that the flaw was not remotely exploitable and Apple’s bug bounty program also didn’t cover macOS. Apple, on the other hand, hasn’t responded to the news or released any statement in relation to the findings of Siguza. We will update the article when Apple responds.

Unpatched eBay vulnerability leaves shoppers at risk of downloading malware

Unpatched eBay vulnerability leaves shoppers at risk of downloading malware

Be extra careful the next time you visit a suspicious-looking eBay store page. According to Help Net Security, researchers from the Check Point security firm have discovered a vulnerability in the eBay platform that allows criminals to distribute malware by bypassing the site’s code validation process and control the code themselves. MUST SEE: 15 paid iPhone apps on sale for free right now Here’s how it works: an attacker sets up a store page with listings for products. On the page, a pop-up message will appear telling customers that they can receive a limited-time discount if they download the eBay mobile app. By clicking the download button, the user will unknowingly download the code and put their device at risk. “The eBay attack flow provides cybercriminals with a very easy way to target users: sending a link to a very attractive product to execute the attack. The main threat is spreading malware and stealing private information. Another threat is that an attacker could have an alternate login option pop up via Gmail or Facebook and hijack the user’s account,” said Oded Vanunu, Security Research Group Manager at Check Point. Although Check Point made eBay aware of the vulnerability on December 15th, 2015, […]
