Deeper analysis
Nortek Linear eMerge E3-Series devices before version 0.32-08f contain an OS command injection vulnerability tracked as CVE-2022-31499. The flaw resides in the handling of the ReaderNo parameter and stems from an incomplete remediation of the earlier CVE-2019-7256 issue. It carries a CVSS 3.1 base score of 9.8 and is classified under CWE-78.
An unauthenticated attacker with network access can supply crafted input to ReaderNo and execute arbitrary operating-system commands on the affected device, resulting in full compromise of confidentiality, integrity, and availability.
Public references include a detailed proof-of-concept exploit published on Packet Storm and an accompanying technical write-up on GitHub by researcher Omar Hashem, confirming remote unauthenticated command execution is achievable in practice. The EPSS score has reached a peak of 0.9380 with a current value of 0.9325.
