Several Vulnerabilities Identified In Emerson OpenEnterprise – Disposable mail news

Recently four vulnerabilities were found in Emerson OpenEnterprise and were accounted for to the vendor in December 2019 with the patches released a couple of months later.

Roman Lozko, a researcher at Kaspersky’s ICS CERT unit, was responsible for the identification of the flaws, and the security holes found by him have been depicted as ‘heap-based cushion buffer, missing authentication, improper ownership management, and weak encryption issues.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and Kaspersky published advisories for three of the vulnerabilities a week ago. The rest of the vulnerability was described by Kaspersky in a previous advisory.

As indicated by Emerson, OpenEnterprise is explicitly intended to address the prerequisites of associations focusing on oil and gas production, transmission, and distribution.

The initial two followed as CVE-2020-6970 and CVE-2020-10640 are depicted as critical, as they can allow an attacker to remotely execute discretionary code with ‘elevated privileges’ on devices running OpenEnterprise.

Vladimir Dashchenko, a security expert at Kaspersky, says an attacker could misuse these vulnerabilities either from the system or directly from the internet. Notwithstanding, there don’t give off an impression of being any occurrences of the affected product exposed to the internet.

“The most critical vulnerabilities allow remote attackers to execute any command on a computer with OpenEnterprise on it with system privileges, so this might lead to any possible consequences,”

 “Based on Shodan statistics, currently there are no directly exposed OpenEnterprise SCADA systems available,” Dashchenko explained. “It means that asset owners with installed OpenEnterprise are definitely following the basic security principles for industrial control systems.”

The rest of the vulnerabilities can be exploited to ‘escalate privileges’ and to acquire passwords for OpenEnterprise user accounts, yet exploitation in the two cases requires local access to the targeted system.

Biometric Data Exposure Vulnerability in OnePlus 7 Pro Android Phones Highlighted TEE Issues – Disposable mail news

In July 2019, London based Synopsys Cybersecurity Research Center discovered a vulnerability in OnePlus 7 Pro devices manufactured by Chinese smartphone maker OnePlus. The flaw that could have been exploited by hackers to obtain users’ fingerprints was patched by the company with a firmware update it pushed in the month of January this year. As per the findings, the flaw wasn’t an easy one to be exploited but researchers pointed out the possibility of a bigger threat in regard to TEEs and TAs.

Synopsys CyRC’s analysis of the vulnerability referred as CV toE-2020-7958, states that it could have resulted in the exposure of OnePlus 7 pro users’ biometric data. The critical flaw would have allowed authors behind malicious android applications with root privileges to obtain users’ bitmap fingerprint images from the device’s Trusted Execution Environment (TEE), a technique designed to protect sensitive user information by keeping the Android device’s content secure against illicit access.

As it has become increasingly complex for malicious applications to acquire root privileges on Android devices, the exploitation of the flaw would have been an arduous task and might also be an unlikely one given the complexity of the successful execution. Meanwhile, the fix has been made available for months now–
ensuring the protection of the users.

However, the issue with Trusted Execution Environments (TEEs) and Trusted Applications (TAs) remains the major highlight of Synopsys’s advisory released on Tuesday, “Upon obtaining root privileges in the REE [Rich Execution Environment], it becomes possible to directly communicate with the factory testing APIs exposed by Trusted Applications (TAs) running in the TEE. This attacker invokes a sequence of commands to obtain raw fingerprint images in the REE,” it read.

While explaining the matter, Travis Biehn, principal consultant at Synopsys, told, “Of course, people’s fingerprints don’t usually change. As attackers become successful in retrieving and building large datasets of people’s fingerprints, the usefulness of naïve fingerprint recognition in any application as a security control is permanently diminished,”

“A further possible consequence is that fingerprints become less trustworthy as evidence in our justice systems.”

“…this vulnerability shows that there’there are challenges with Trusted Execution Environments (TEEs) and Trusted Applications (TAs); these are software components that are opaque to most (by design), expertise is limited, and typically involve long supply chains. These factors together mean there’there are opportunities for organizations to make a mistake, and hard for security experts to catch at the right time,” he further added.

The flaw would have allowed attackers to recreate the targeted user’s complete fingerprint and then use it to generate a counterfeit fingerprint that further would have assisted them in accessing other devices relying upon biometric authentication.
