Zyxel Multiple NAS Devices OS Command Injection Vulnerability

Multiple Zyxel network-attached storage (NAS) devices contain a pre-authentication command injection vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code.

Added to KEV: 2022-03-25Federal patch deadline: 2022-04-15

Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

This vulnerability affects multiple Zyxel network-attached storage (NAS) devices, allowing a remote attacker to execute arbitrary code without needing to authenticate. The high EPSS score of 0.94312 indicates a very high likelihood of exploitation, making this a critical concern.

This flaw is actively being exploited in the wild and is listed in CISA's KEV catalog, confirming its active use by attackers. The vulnerability is remotely exploitable without authentication.

Recommended Action

Organizations should apply available patches or firmware updates for their Zyxel NAS devices immediately. Generic hardening measures for network-attached storage should also be considered.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2020-9054 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-2020-9054 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.
