Vulnerabilities

Critical Patch Update from Oracle

Oracle announced that more than half of the patches address vulnerabilities related to unauthenticated remote exploitation. The leader in the count of fixes was Oracle Communications, where 56 vulnerabilities could be exploited remotely without authentication. Behind it is MySQL, where 10 vulnerabilities were also exploited.

The overall product portfolio is extensive: from financial services and retail applications to commercial database server solutions, Essbase, Enterprise Manager, GoldenGate, utility applications and virtualization systems.

It is recommended to install Critical Patch Update from Oracle for your existing products as soon as possible.

Google Chrome vulnerabilities

Google has fixed a bunch of 19 vulnerabilities in the Chrome browser. 3 vulnerabilities from the update package were discovered by the developers themselves, for the other 16 the company had to pay bonuses to third-party specialists

Separately, Google has said it has improved overall Chrome security by removing several features, such as support for TLS 1.0 / 1.1 and FTP protocols, for non-IPv4 digit-ending URLs and for U2F.

The new version of the browser also introduces restrictions on the size of cookies.

WinRAR web notifier

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

To carry out an MITM attack via this vulnerability, an attacker should create a malicious Wi-Fi access point, hack a router and spoof DNS, or be on the same network with the victim.


Tools

Limelighter: tool for generating fake code signing certificates or signing real ones.

ThreadStackSpoofer: Thread Stack Spoofing – PoC for an advanced In-Memory evasion technique on Windows allowing to better hide injected shellcode’s memory allocation from scanners and analysts.

PowerShx: Unmanaged PowerShell execution using DLLs or a standalone executable.

News

MITRE pyramid of pain

American organization MITRE announced the release of a new 10th version of the ATT&CK matrix. The release updates Techniques, Groups, and Software for Enterprise, Mobile, and ICS.

The biggest change was an update to the Data Source and Data Component structure in the Enterprise ATT&CK. The matrix now fully aggregates the information from these structures into itself, allowing you to conveniently discover the relationships between the data object and the possible variations of sub-techniques implemented on their basis. In total, the 10th version of the MITRE ATT&CK matrix contains 14 tactics, 188 methods, 379 sub-techniques, 129 groups, and 638 programs.

Hacker claims to steal identity cards of all argentine citizens

The first evidence that someone had hacked the National Register of Persons (Registro Nacional de las Personas – the agency that issues passports of citizens) appeared on Twitter earlier this month. A user under the account @AnibalLeaks posted photos of the personal data of 44 Argentinean celebrities.

In a press release on October 13, Argentina’s Ministry of the Interior announced that a VPN account assigned to the Ministry of Health was used to query the agency’s database “at the very moment the data was posted to Twitter”. The hacker, whom The Record reporters managed to contact, indirectly confirmed the version of the Argentine Ministry of Internal Affairs.

Gummy Browsers attack

In a Gummy Browsers attack, attackers trap a victim to their website in order to obtain their digital fingerprint, which can be used to spoof the victim’s identity on the target platform. The researchers said that by using the Gummy Browsers method, they can trick modern digital fingerprint tracking systems such as FPStalker and Panopticlick for a long time. Digital fingerprint data can be used to bypass authentication (MFA) and fraud detection mechanisms used by many banks and large retailers.
