Cybersecurity researchers have disclosed  two unpatched security vulnerabilities  in the open-source U-Boot boot loader. The issues, which were uncovered in the  IP defragmentation  algorithm implemented in U-Boot by NCC Group, could be abused to achieve arbitrary out-of-bounds write and denial-of-service (DoS). U-Boot is a  boot loader  used in Linux-based embedded systems such as ChromeOS as well as ebook readers such as Amazon Kindle and Kobo eReader. The issues are summarized below - CVE-2022-30790  (CVSS score: 9.6) - Hole Descriptor overwrite in U-Boot IP packet defragmentation leads to an arbitrary out-of-bounds write primitive. CVE-2022-30552  (CVSS score: 7.1) - Large buffer overflow leads to DoS in U-Boot IP packet defragmentation code It's worth noting that both the flaws are exploitable only from the local network. But doing so can enable an attacker to root the devices and lead to a DoS by crafting a malformed packet. The s...

Microsoft's Digital Crimes Unit (DCU) last week disclosed that it had taken legal proceedings against an Iranian threat actor dubbed  Bohrium  in connection with a spear-phishing operation. The adversarial collective is said to have targeted entities in tech, transportation, government, and education sectors located in the U.S., Middle East, and India. "Bohrium actors create fake social media profiles, often posing as recruiters," Amy Hogan-Burney of the DCU  said  in a tweet. "Once personal information was obtained from the victims, Bohrium sent malicious emails with links that ultimately infected their target's computers with malware." According to an  ex parte order  shared by the tech giant, the goal of the intrusions was to steal and exfiltrate sensitive information, take control over the infected machines, and carry out remote reconnaissance. To halt the malicious activities of Bohrium, Microsoft said it took down 41 ".com," ".info...

"Shifting (security)" left approach in Software Development Life Cycle (SDLC) means starting security earlier in the process. As organizations realized that software never comes out perfectly and are riddled with many exploitable holes, bugs, and business logic vulnerabilities that require going back to fix and patch, they understood that building secure software requires incorporating and consolidating numerous resources. This conclusion led DevOps and R&D leaders to become proactive, acquiring technology to find and close these gaps in advance, with the aim of reducing the cost and effort while improving the quality of their outcomes.  With emerging comprehensive  continuous security validation technology , the demonstrated benefits of 'shifting left' as a fundamental part of SDLC can now be applied to your cybersecurity program, with results far exceeding the purely technical aspects of security posture management.  At the development level, the conceptuali...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and Food and Drug Administration (FDA) have issued an advisory about critical security vulnerabilities in Illumina's next-generation sequencing ( NGS ) software. Three of the flaws are rated 10 out of 10 for severity on the Common Vulnerability Scoring System ( CVSS ), with two others having severity ratings of 9.1 and 7.4. The issues impact software in medical devices used for "clinical diagnostic use in sequencing a person's DNA or testing for various genetic conditions, or for research use only,"  according to the FDA . "Successful exploitation of these vulnerabilities may allow an unauthenticated malicious actor to take control of the affected product remotely and take any action at the operating system level," CISA  said  in an alert. "An attacker could impact settings, configurations, software, or data on the affected product and interact through the affected product with the c...

A suspected state-aligned threat actor has been attributed to a new set of attacks exploiting the Microsoft Office "Follina" vulnerability to target government entities in Europe and the U.S. Enterprise security firm Proofpoint said it blocked attempts at exploiting the remote code execution flaw, which is being tracked as  CVE-2022-30190  (CVSS score: 7.8). No less than 1,000 phishing messages containing a lure document were sent to the targets. "This campaign masqueraded as a salary increase and utilized an RTF with the exploit payload downloaded from 45.76.53[.]253," the company  said  in a series of tweets. The payload, which manifests in the form of a PowerShell script, is Base64-encoded and functions as a downloader to retrieve a second PowerShell script from a remote server named "seller-notification[.]live." "This script checks for virtualization, steals information from local browsers, mail clients and file services, conducts machine re...

Atlassian on Friday rolled out fixes to address a  critical security flaw  affecting its Confluence Server and Data Center products that have come under active exploitation by threat actors to achieve remote code execution. Tracked as  CVE-2022-26134 , the issue is similar to  CVE-2021-26084  — another security flaw the Australian software company patched in August 2021. Both relate to a case of Object-Graph Navigation Language ( OGNL ) injection that could be exploited to achieve arbitrary code execution on a Confluence Server or Data Center instance. The newly discovered shortcoming impacts all supported versions of Confluence Server and Data Center, with every version after 1.3.0 also affected. It's been resolved in the following versions - 7.4.17 7.13.7 7.14.3 7.15.2 7.16.4 7.17.4 7.18.1 According to stats from internet asset discovery platform  Censys , there are about 9,325 services across 8,347 distinct hosts running a vulnerable versi...

GitLab has moved to address a critical security flaw in its service that, if successfully exploited, could result in an account takeover. Tracked as  CVE-2022-1680 , the issue has a CVSS severity score of 9.9 and was discovered internally by the company. The security flaw affects all versions of GitLab Enterprise Edition (EE) starting from 11.10 before 14.9.5, all versions starting from 14.10 before 14.10.4, and all versions starting from 15.0 before 15.0.1. "When group SAML SSO is configured, the SCIM feature (available only on Premium+ subscriptions) may allow any owner of a Premium group to invite arbitrary users through their username and email, then change those users' email addresses via SCIM to an attacker controlled email address and thus — in the absence of 2FA — take over those accounts," GitLab  said . Having achieved this, a malicious actor can also change the display name and username of the targeted account, the DevOps platform provider cautioned in its...
