Mitigating Controls (NIST 800-53 r5)AI

prevent

Information Input Validation directly prevents buffer overflows by enforcing bounds checking and sanitization on text file imports, addressing the core cause of this CVE.

prevent

Flaw Remediation requires timely patching or removal of vulnerable software like 10-Strike Network Inventory Explorer Pro 9.31 to eliminate the buffer overflow vulnerability.

prevent

Memory Protection implements mechanisms like address space layout randomization and data execution prevention to comprehensively mitigate exploitation of buffer overflows leading to RCE.

Security SummaryAI

CVE-2021-47772 is a buffer overflow vulnerability (CWE-787) affecting 10-Strike Network Inventory Explorer Pro version 9.31, specifically in its text file import functionality. This flaw enables remote code execution, as attackers can craft a malicious text file with a carefully constructed payload to trigger a reverse shell and execute arbitrary code on the target system. The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its network accessibility, low attack complexity, lack of required privileges or user interaction, and high impacts on confidentiality, integrity, and availability.

Remote attackers require no authentication or privileges to exploit this vulnerability. By delivering a specially crafted text file—potentially via network share, email, or other means accessible to the import function—they can trigger the buffer overflow during processing. Successful exploitation results in arbitrary code execution on the target system, including the establishment of a reverse shell for full remote control.
