CVE-2025-23006 is a critical zero-day vulnerability affecting SonicWall Secure Mobile Access (SMA) 1000 series appliances. This vulnerability, categorized as a deserialization of untrusted data flaws, resides within the Appliance Management Console (AMC) and Central Management Console (CMC). Exploited by remote attackers without requiring authentication, this vulnerability allows for executing arbitrary code on the affected devices, granting attackers complete control. This vulnerability, assigned a CVSS v3.1 base score of 9.8 (Critical) with a vector string of AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, has been actively exploited in the wild by threat actors.
Impact
The impact of CVE-2025-23006 is highly severe, as it enables remote, unauthenticated attackers to execute arbitrary operating system commands on vulnerable SonicWall SMA 1000 appliances. This vulnerability poses a significant risk to organizations, as these appliances are widely used for secure remote access in enterprises and critical infrastructure environments. Exploitation can result in full system compromise, allowing threat actors to exfiltrate sensitive data, steal credentials, and move laterally within networks to launch further attacks, such as ransomware. The pre-authentication nature of the flaw makes it particularly dangerous, as attackers do not require valid credentials to exploit it, significantly increasing the likelihood of successful attacks.
