CISA KEV Advisory
Nice Linear eMerge E3-Series OS Command Injection Vulnerability
Nice Linear eMerge E3-Series contains an OS command injection vulnerability that allows an attacker to conduct remote code execution.
Contact the vendor for guidance on remediating firmware, per their advisory.
Risk Analysis
An OS command injection vulnerability in Nice Linear eMerge E3-Series allows an attacker to execute arbitrary commands remotely. The extremely high EPSS score indicates a very high likelihood of exploitation, and its inclusion in CISA's KEV confirms it is actively exploited, making this a critical vulnerability.
This vulnerability is actively exploited in the wild, confirming that weaponized exploits are available and being used by attackers. This flaw is remotely exploitable.
Update Nice Linear eMerge E3-Series devices to the latest firmware version provided by the vendor. Implement network segmentation and restrict access to these devices to trusted networks only.
Technical Analysis
CVE-2019-7256 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2019-7256 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
