Advisories

A non-exhaustive list of public/released through vulnerability affiliation programs Vulnerabilities & CVEs discovered by VoidSec.

All releases are governed by our Vulnerability Disclosure Policy.

Severity: High

Wowza Streaming Engine v.<= 4.8.16+1 (build 20211129092949) is vulnerable to the Log4j JNDI injection, affecting the 'j_username' username field, in the login page as well as other HTTP headers. Attackers exploiting this issue will be able to achieve remote code execution (RCE) in the context of the NT AUTHORITY\SYSTEM Windows user managing the service.
All vendors affected by the Log4j vulnerability must use the CVE-2021-44228 when referring to this vulnerability in their own products. At present, MITRE does not offer an option for a vendor to associate its own unique CVE ID with this same underlying vulnerability.

Severity: High

Micro-Star International (MSI) Center Pro v. <= 2.0.16.0 is vulnerable to multiple Privilege Escalation (LPE/EoP) vulnerabilities in the following drivers components:

  • atidgllk.sys - D299A2420F92A1F0150265F26D496AE587A681DA

  • WinRing0.sys - 8AC34EB21B9B38F67CD29684C45696C20AB2E75A

All the vulnerabilities are triggered by sending specific IOCTL requests and will allow to:

  • Directly interact with physical memory via the MmMapIoSpace function call, mapping physical memory into a virtual address user-space.
  • Read/write Model-Specific Registers (MSRs) via the __readmsr/__writemsr functions calls.
  • Read/write 1/2/4 bytes to or from an IO port.

Attackers could exploit these issues to achieve local privilege escalation from low-privileged users to NT AUTHORITY\SYSTEM.
