Critical Bugs and Backdoor Found in GeoVision's Fingerprint and Card Scanners

June 25, 2020Ravie Lakshmanan
GeoVision, a Taiwanese manufacturer of video surveillance systems and IP cameras, recently patched three of the four critical flaws impacting its card and fingerprint scanners that could've potentially allowed attackers to intercept network traffic and stage man-in-the-middle attacks. In a report shared exclusively with The Hacker News, enterprise security firm Acronis said it discovered the vulnerabilities last year following a routine security audit of a Singapore-based major retailer. "Malicious attackers can establish persistence on the network and spy on internal users, steal data — without ever getting detected," Acronis said. "They can reuse your fingerprint data to enter your home and/or personal devices, and photos can be easily reused by malicious actors to perpetrate identity theft based on biometric data." In all, the flaws affect at least 6 device families, with over 2,500 vulnerable devices discovered online across Brazil, US, Germany, Ta

Oracle E-Business Suite Flaws Let Hackers Hijack Business Operations

June 16, 2020Ravie Lakshmanan
If your business operations and security of sensitive data rely on Oracle's E-Business Suite (EBS) , make sure you recently updated and are running the latest available version of the software. In a report released by enterprise cybersecurity firm Onapsis and shared with The Hacker News, the firm today disclosed technical details for vulnerabilities it reported in Oracle's E-Business Suite (EBS), an integrated group of applications designed to automate CRM, ERP, and SCM operations for organizations. The two vulnerabilities, dubbed " BigDebIT " and rated a CVSS score of 9.9, were patched by Oracle in a critical patch update (CPU) pushed out earlier this January. But the company said an estimated 50 percent of Oracle EBS customers have not deployed the patches to date. The security flaws could be exploited by bad actors to target accounting tools such as General Ledger in a bid to steal sensitive information and commit financial fraud. According to the research
Intel CPUs Vulnerable to New 'SGAxe' and 'CrossTalk' Side-Channel Attacks

Intel CPUs Vulnerable to New 'SGAxe' and 'CrossTalk' Side-Channel Attacks

June 10, 2020Ravie Lakshmanan
Cybersecurity researchers have discovered two distinct attacks that could be exploited against modern Intel processors to leak sensitive information from the CPU's trusted execution environments (TEE). Called SGAxe , the first of the flaws is an evolution of the previously uncovered CacheOut attack (CVE-2020-0549) earlier this year that allows an attacker to retrieve the contents from the CPU's L1 Cache. "By using the extended attack against the Intel-provided and signed architectural SGX enclaves, we retrieve the secret attestation key used for cryptographically proving the genuinity of enclaves over the network, allowing us to pass fake enclaves as genuine," a group of academics from the University of Michigan said. The second line of attack, dubbed CrossTalk by researchers from the VU University Amsterdam, enables attacker-controlled code executing on one CPU core to target SGX enclaves running on a completely different core, and determine the enclave'

The Indian Government said it has addressed a critical vulnerability in its secure document wallet service Digilocker that could have potentially let a remote attacker bypass mobile one-time passwords (OTP) and sign in as other users. Discovered separately by two independent bug bounty researchers, Mohesh Mohan and Ashish Gahlot , the vulnerability could have been exploited easily to unauthorisedly access sensitive documents uploaded by targeted users' on the Government-operated platform. "The OTP function lacks authorization which makes it possible to perform OTP validation with submitting any valid users details and then manipulation flow to sign in as a totally different user," Mohesh Mohan said in a disclosure shared with The Hacker News. With over 38 million registered users, Digilocker is a cloud-based repository that acts as a digital platform to facilitate online processing of documents and speedier delivery of various government-to-citizen services.

Exclusive – Any Mitron (Viral TikTok Clone) Profile Can Be Hacked in Seconds

May 30, 2020Mohit Kumar
Mitron (means "friends" in Hindi), you have been fooled again! Mitron is not really a 'Made in India' product, and the viral app contains a highly critical, unpatched vulnerability that could allow anyone to hack into any user account without requiring interaction from the targeted users or their passwords. I am sure many of you already know what TikTok is, and those still unaware, it's a highly popular video social platform where people upload short videos of themselves doing things like lip-syncing and dancing. The wrath faced by Chinese-owned TikTok from all directions—mostly due to data security and ethnopolitical reasons—gave birth to new alternatives in the market, one of which is the Mitron app for Android. Mitron video social platform recently caught headlines when the Android app crazily gained over 5 million installations and 250,000 5-star ratings in just 48 days after being released on the Google Play Store. Popped out of nowhere, Mitron i

May 19, 2020Ravie Lakshmanan
Academics from École Polytechnique Fédérale de Lausanne (EPFL) disclosed a security vulnerability in Bluetooth that could potentially allow an attacker to spoof a remotely paired device, exposing over a billion of modern devices to hackers. The attacks, dubbed Bluetooth Impersonation AttackS or BIAS, concern Bluetooth Classic, which supports Basic Rate (BR) and Enhanced Data Rate (EDR) for wireless data transfer between devices. "The Bluetooth specification contains vulnerabilities enabling to perform impersonation attacks during secure connection establishment," the researchers outlined in the paper. "Such vulnerabilities include the lack of mandatory mutual authentication, overly permissive role switching, and an authentication procedure downgrade." Given the widespread impact of the vulnerability, the researchers said they responsibly disclosed the findings to the Bluetooth Special Interest Group (SIG), the organization that oversees the development o

May 01, 2020Ravie Lakshmanan
Two severe security flaws have been discovered in the open-source SaltStack Salt configuration framework that could allow an adversary to execute arbitrary code on remote servers deployed in data centers and cloud environments. The vulnerabilities were identified by F-Secure researchers earlier this March and disclosed on Thursday, a day after SaltStack released a patch (version 3000.2) addressing the issues , rated with CVSS score 10. "The vulnerabilities, allocated CVE IDs CVE-2020-11651 and CVE-2020-11652 , are of two different classes," the cybersecurity firm said . "One being authentication bypass where functionality was unintentionally exposed to unauthenticated network clients, the other being directory traversal where untrusted input (i.e., parameters in network requests) was not sanitized correctly allowing unconstrained access to the entire filesystem of the master server." The researchers warned that the flaws could be exploited in the wild imm

CISA Warns Patched Pulse Secure VPNs Could Still Expose Organizations to Hackers

April 17, 2020Ravie Lakshmanan
The United States Cybersecurity and Infrastructure Security Agency (CISA) yesterday issued a fresh advisory alerting organizations to change all their Active Directory credentials as a defense against cyberattacks trying to leverage a known remote code execution (RCE) vulnerability in Pulse Secure VPN servers—even if they have already patched it. The warning comes three months after another CISA alert urging users and administrators to patch Pulse Secure VPN environments to thwart attacks exploiting the vulnerability. "Threat actors who successfully exploited CVE-2019-11510 and stole a victim organization's credentials will still be able to access — and move laterally through — that organization's network after the organization has patched this vulnerability if the organization did not change those stolen credentials," CISA said. CISA has also released a tool to help network administrators look for any indicators of compromise associated with the flaw.

Critical RCE Bug Affects Millions of OpenWrt-based Network Devices

March 24, 2020Mohit Kumar
A cybersecurity researcher today disclosed technical details and proof-of-concept of a critical remote code execution vulnerability affecting OpenWrt , a widely used Linux-based operating system for routers, residential gateways, and other embedded devices that route network traffic. Tracked as CVE-2020-7982 , the vulnerability resides in the OPKG package manager of OpenWrt that exists in the way it performs integrity checking of downloaded packages using the SHA-256 checksums embedded in the signed repository index. While an 'opkg install' command is invoked on the victim system, the flaw could allow a remote man-in-the-middle attacker in a position to intercept the communication of a targeted device to execute arbitrary code by tricking the system into installing a malicious package or software update without verification. If exploited successfully, a remote attacker could gain complete control over the targeted OpenWrt network device, and subsequently, over the netwo

Mukashi: A New Mirai IoT Botnet Variant Targeting Zyxel NAS Devices

March 21, 2020Ravie Lakshmanan
A new version of the infamous Mirai botnet is exploiting a recently uncovered critical vulnerability in network-attached storage (NAS) devices in an attempt to remotely infect and control vulnerable machines. Called " Mukashi ," the new variant of the malware employs brute-force attacks using different combinations of default credentials to log into Zyxel NAS, UTM, ATP, and VPN firewall products to take control of the devices and add them to a network of infected bots that can be used to carry out Distributed Denial of Service (DDoS) attacks. Multiple Zyxel NAS products running firmware versions up to 5.21 are vulnerable to the compromise, Palo Alto Networks' Unit 42 global threat intelligence team said, adding they uncovered the first such exploitation of the flaw in the wild on March 12. Zyxel's Pre-Authentication Command Injection Flaw Mukashi hinges on a pre-authentication command injection vulnerability (tracked as CVE-2020-9054 ), for which a proof-

Poor Rowhammer Fixes On DDR4 DRAM Chips Re-Enable Bit Flipping Attacks

Poor Rowhammer Fixes On DDR4 DRAM Chips Re-Enable Bit Flipping Attacks

March 10, 2020Mohit Kumar
Remember rowhammer vulnerability? A critical issue affecting modern DRAM (dynamic random access memory) chips that could allow attackers to obtain higher kernel privileges on a targeted system by repeatedly accessing memory cells and induce bit flips. To mitigate Rowhammer vulnerability on the latest DDR4 DRAM, many memory chip manufacturers added some defenses under the umbrella term Target Row Refresh (TRR) that refreshes adjacent rows when a victim row is accessed more than a threshold. But it turns out 'Target Row Refresh,' promoted as a silver bullet to mitigate rowhammer attacks, is also insufficient and could let attackers execute new hammering patterns and re-enable the bit-flip attacks on the latest hardware as well. TRRespass: The Rowhammer Fuzzing Tool Tracked as CVE-2020-10255 , the newly reported vulnerability was discovered by researchers at VUSec Lab, who today also released ' TRRespass ,' an open source black box many-sided RowHammer fuzzin
