Vulnerability in WinRAR allows code to run without the user’s knowledge

Published

on

To carry out an attack, you need to create a malicious Wi-Fi access point, hack a router, and spoof DNS.

Positive Technologies Igor Sak-Sakovsky discovered a dangerous vulnerability in the WinRAR file archiver. An issue identified as CVE-2021-35052 exists in the WinRAR web notifier, which is used to display trial period expiration messages. The vulnerability affects WinRAR versions prior to 6.02 beta 1.

To display a message about the expiration of the trial period, the web component redirects to HHPS: //notifier.win-rar.com/. The vulnerability allows a remote unauthorized person to intercept requests sent to them and thereby carry out a man-in-the-middle (MITM) attack, create a backdoor, and even remotely execute code.

As explained by the researcher, the vulnerability exists due to the use of the incorrectly configured webbrowser module by the web notifier component.

According to Sak-Sakovsky, in order to carry out an MITM attack through this vulnerability, an attacker needs to create a malicious Wi-Fi access point, hack a router and spoof DNS, or be on the same network with the victim.

An attacker can use an SMB server to execute code remotely, but there are restrictions on the black list of executable file extensions. So, when you run files with the bat, vbs, exe and msi extensions, a message about the malicious file will appear, suggesting possible actions with them. However, since WinRAR does not have an automatic update mechanism, and vulnerable versions are common, attackers can bypass the restrictions and hide the launch using old exploits for WinRAR or Microsoft Office.

Vodafone is suing the UK over a contract to develop a hacker-proof communication line

Published

on

The company considers it unfair that the contract was awarded to Fujitsu, although both bidders did not meet the requirements.

Mobile operator Vodafone filed in court against the UK government after losing a tender to develop a hacker-proof communications system, in which the Japanese company Fujitsu also took part.

Although both bidders were found to have failed to meet the government’s minimum requirements, Vodafone believes Fujitsu was unfairly awarded a £ 184m ($ 254m) contract to improve the communications system used by 532 British embassies and other agencies.

The Echo 2 project aims to provide secure communications for the UK Foreign and Commonwealth Office, employees and agents in over 170 countries.

According to the government, the current communications system operated by Vodafone is “outdated” and poses a risk to national security.

Vodafone went to court after Cable & Wireless, acquired by the operator in 2012, lost its long-term contract for the Echo 1.

“We do not believe that the procurement process was carried out correctly. The contracting authority itself admitted that the Fujitsu Solution was ‘not fit for purpose,’ said a Vodafone spokesman.

According to foreign ministry lawyers, Fujitsu’s proposal had problems with two requirements, but generally met the terms of the tender. Fujitsu representatives did not comment on the situation.

The trial in this case is scheduled for January 2022. The court allowed the UK government to enter into a “conditional contract” with Fujitsu. The details of the contract were not disclosed due to security concerns.
