Citrix has released  security updates  to address a critical authentication bypass flaw in the application delivery controller (ADC) and Gateway products that could be exploited to take control of affected systems. Successful exploitation of the issues could enable an adversary to gain authorized access, perform remote desktop takeover, and even circumvent defenses against login brute-force attempts under specific configurations. CVE-2022-27510  - Unauthorized access to Gateway user capabilities CVE-2022-27513  - Remote desktop takeover via phishing CVE-2022-27516  - User login brute-force protection functionality bypass The following supported versions of Citrix ADC and Citrix Gateway are affected by the flaws - Citrix ADC and Citrix Gateway 13.1 before 13.1-33.47  Citrix ADC and Citrix Gateway 13.0 before 13.0-88.12  Citrix ADC and Citrix Gateway 12.1 before 12.1.65.21 Citrix ADC 12.1-FIPS before 12.1-55.289 Citrix ADC 12.1-NDcPP befor...

Cybersecurity researchers have disclosed details of a new vulnerability in a system used across oil and gas organizations that could be exploited by an attacker to inject and execute arbitrary code. The high-severity issue, tracked as  CVE-2022-0902  (CVSS score: 8.1), is a path-traversal vulnerability in ABB Totalflow  flow computers and remote controllers . "Attackers can exploit this flaw to gain root access on an ABB flow computer, read and write files, and remotely execute code," industrial security company Claroty  said  in a report shared with The Hacker News. ABB, a Swedish-Swiss industrial automation firm, has since released  firmware updates  as of July 14, 2022, following responsible disclosure. Flow computers are special-purpose electronic instruments used by petrochemical manufacturers to interpret data from flow meters and calculate and record the volume of substances such as natural gas, crude oils, and other hydrocarbon fluids at ...

The rise in the costs of data breaches, ransomware, and other cyber attacks leads to rising cyber insurance premiums and more limited cyber insurance coverage. This cyber insurance situation increases risks for organizations struggling to find coverage or facing steep increases. Some  Akin Gump Strauss Hauer & Feld LLP's  law firm clients, for example, reported a three-fold increase in insurance rates, and carriers are making "a huge pullback" on coverage limits in the past two years. Their cybersecurity practice co-head, Michelle Reed, adds, "The reduced coverage amount can no longer shield policyholders from cyber losses. A $10 million policy can end up with a $150,000 limit on cyber frauds." The cyber-insurance situation is so concerning that the U.S. Treasury Department recently issued a  request for public input  on a potential federal cyber-insurance response program. This request is in addition to the assessment led conjointly by the Federal Insura...

PC maker Lenovo has addressed yet another set of three shortcomings in the Unified Extensible Firmware Interface (UEFI) firmware affecting several Yoga, IdeaPad, and ThinkBook devices. "The vulnerabilities allow disabling UEFI Secure Boot or restoring factory default Secure Boot databases (incl. dbx): all simply from an OS," Slovak cybersecurity firm ESET  explained  in a series of tweets. UEFI refers to software that acts as an interface between the operating system and the firmware embedded in the device's hardware. Because UEFI is  responsible  for launching the operating system when a device is powered on, it has made the technology an attractive option for threat actors looking to  drop malware  that's difficult to detect and remove. Viewed in that light, the flaws, tracked as CVE-2022-3430, CVE-2022-3431, and CVE-2022-3432, could be abused by an adversary to turn off Secure Boot, a security mechanism that's designed to prevent malicious programs ...

The Russia-linked APT29 nation-state actor has been found leveraging a "lesser-known" Windows feature called Credential Roaming following a successful phishing attack against an unnamed European diplomatic entity. "The diplomatic-centric targeting is consistent with Russian strategic priorities as well as historic APT29 targeting," Mandiant researcher Thibault Van Geluwe de Berlaere  said  in a technical write-up. APT29, a Russian espionage group also called Cozy Bear, Iron Hemlock, and The Dukes, is  known  for its intrusions aimed at collecting intelligence that align with the country's strategic objectives. It's believed to be sponsored by the Foreign Intelligence Service (SVR). Some of the adversarial collective's cyber activities are tracked publicly under the moniker  Nobelium , a threat cluster responsible for the widespread supply chain compromise through SolarWinds software in December 2020. The Google-owned threat intelligence and inciden...
