SonicWall has published an  advisory  warning of a trio of security flaws in its Secure Mobile Access (SMA) 1000 appliances, including a high-severity authentication bypass vulnerability. The weaknesses in question impact SMA 6200, 6210, 7200, 7210, 8000v running firmware versions 12.4.0 and 12.4.1. The list of vulnerabilities is below - CVE-2022-22282  (CVSS score: 8.2) - Unauthenticated Access Control Bypass CVE-2022-1702  (CVSS score: 6.1) - URL redirection to an untrusted site (open redirection) CVE-2022-1701  (CVSS score: 5.7) - Use of a shared and hard-coded cryptographic key Successful exploitation of the aforementioned bugs could allow an attacker to unauthorized access to internal resources and even redirect potential victims to malicious websites.

SonicWall noted that the flaws do not affect SMA 1000 series running versions earlier than 12.4.0, SM

Email security firm Mimecast on Tuesday revealed that the state-sponsored SolarWinds hackers who broke into its internal network also downloaded source code out of a limited number of repositories. "The threat actor did access a subset of email addresses and other contact information and hashed and salted credentials," the company  said  in a write-up detailing its investigation, adding the adversary "accessed and downloaded a limited number of our source code repositories, as the threat actor is reported to have done with other victims of the SolarWinds Orion supply chain attack." But Mimecast said the source code downloaded by the attackers was incomplete and would be insufficient to build and run any aspect of the Mimecast service and that it did not find signs of any tampering made by the threat actor to the build process associated with the executables that are distributed to its customers.  On January 12, Mimecast  disclosed  that "a sophisticated th

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

Mimecast said on Tuesday that "a sophisticated threat actor" had compromised a digital certificate it provided to certain customers to securely connect its products to Microsoft 365 (M365) Exchange. The discovery was made after the breach was notified by Microsoft, the London-based company  said in an alert  posted on its website, adding it's reached out to the impacted organizations to remediate the issue. The company didn't elaborate on what type of certificate was compromised, but Mimecast offers  seven different digital certificates  based on the geographical location that must be uploaded to M365 to create a server Connection in Mimecast. "Approximately 10 percent of our customers use this connection," the company said. "Of those that do, there are indications that a low single digit number of our customers' M365 tenants were targeted." Mimecast is a cloud-based email management service for Microsoft Exchange and Microsoft Office 365
