Vulnerabilities and Patches

  • Check Point Research has recently exposed a new Out-Of-Bounds read-write vulnerability, tracked as CVE-2020-1910, in the WhatsApp instant messaging app. The issue, which could have allowed a sophisticated attacker to read sensitive information from WhatsApp memory, was subsequently patched.
  • Threat actors are currently exploiting the Atlassian Confluence remote code execution vulnerability that was recently unveiled, aiming at installing crypto miners.

  • Sixteen vulnerabilities dubbed BrakTooth are affecting Bluetooth stacks on system-on-a-chip and could impact billions of varied devices including industrial equipment. The vulnerabilities could allow a threat actor a range of possibilities, including the ability to execute malware on a device.
  • Cisco has announced patching a severe authentication bypass vulnerability (CVE-2021-34746) in its Enterprise Network Function Virtualization Infrastructure Software (NFVIS) which could have allowed a remote attacker to circumvent authentication and log into a vulnerable device as an administrator.
