SECURITY POSTURE
SonicWall has a poor security posture characterized by a high frequency of critical remote code execution (RCE) and SQL injection vulnerabilities across its SMA100 and SMA1000 appliance lines, with multiple flaws added to CISA's Known Exploited Vulnerabilities catalog and active exploitation confirmed by vendors and security researchers.
Notable failures
- CVE-2021-20038: Unauthenticated stack-based buffer overflow RCE on SMA100
- CVE-2025-23006: Unauthenticated deserialization RCE on SMA1000
- CVE-2024-40766: Improper access control RCE linked to ransomware
- CVE-2024-53704: Authentication bypass on SSLVPN
- CVE-2021-20016: Unauthenticated SQL injection for credential access on SMA100
- CVE-2026-15410: Code injection vulnerability on SMA1000
Patterns: Repeated critical RCE vulnerabilities in SMA100/SMA1000 management interfaces; Unauthenticated SQL injection flaws enabling credential theft; Authentication bypasses in SSLVPN and management consoles; Vulnerabilities added to CISA Known Exploited Vulnerabilities catalog
