| CVE-2025-23006 | Unauthenticated Deserialization RCE in SonicWall SMA1000 Appliances CVE-2025-23006 is a deserialization of untrusted data flaw (CWE-502) in the Appliance Management Console (AMC) and Central Management Console (CMC) of SonicWall SMA1000 secure-access appliances. A remote, unauthenticated attacker who can reach a vulnerable console can submit crafted serialized data that, when processed, executes arbitrary operating-system commands on the appliance. Successful exploitation yields OS-level command execution, which is enough to fully compromise the appliance, pivot into the networks it protects, or stage ransomware. Any organization running a SonicWall SMA1000 appliance whose AMC or CMC is reachable — including management consoles exposed to the internet or to shared management networks — is affected. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2025-01-24 with known ransomware use, and EPSS assigns a 23.4% probability of exploitation within 30 days (98th percentile), although no public proof-of-concept is known and a CVSS score has not yet been published. Do: Apply SonicWall's fix or vendor-specified mitigations immediately, per CISA's KEV required action; the available data does not state fixed version numbers, so use SonicWall's advisory to identify the correct firmware. Until patched, restrict AMC/CMC access to trusted management networks and remove any direct internet exposure of the consoles. Because ransomware use is known, hunt for indicators of compromise on internet-reachable SMA1000 appliances, including unexpected processes, new accounts, and unusual outbound connections. | 9.8 | 23% | KEV ransomware |

U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds SonicWall SMA1000 vulnerability to its Known Exploited Vulnerabilities catalog.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a SonicWall SMA1000 Appliance Management Console (AMC) and Central Management Console (CMC) vulnerability, tracked as CVE-2025-23006 to its Known Exploited Vulnerabilities (KEV) catalog.
This week, SonicWall warned customers of a critical security vulnerability, tracked as CVE-2025-23006 (CVSS score of 9,8) impacting its Secure Mobile Access (SMA) 1000 Series appliances. The vulnerability is a Pre-authentication deserialization of untrusted data issue in the SMA1000 Appliance Management Console (AMC) and Central Management Console (CMC) that has been likely exploited in attacks in the wild as a zero-day.
“Pre-authentication deserialization of untrusted data vulnerability has been identified in the SMA1000 Appliance Management Console (AMC) and Central Management Console (CMC), which in specific conditions could potentially enable a remote unauthenticated attacker to execute arbitrary OS commands.” reads the advisory. “IMPORTANT: “SonicWall PSIRT has been notified of possible active exploitation of the referenced vulnerability by threat actors. We strongly advises users of the SMA1000 product to upgrade to the hotfix release version to address the vulnerability.”
The flaw impacts version 12.4.3-02804 (platform-hotfix) and earlier versions, SonicWall urges customers to address the vulnerability as soon as possible.
The company released Version 12.4.3-02854 which addresses the flaw.
Microsoft Threat Intelligence Center (MSTIC) discovered the vulnerability.
SonicWall has not disclosed details about the attacks that exploited the flaw as a zero-day, nor the attackers’ motivations
Experts also recommend restricting AMC and CMC access to trusted sources and following the SMA1000 Administration Guide’s best practices to reduce the vulnerability’s impact.
According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog.
Experts also recommend private organizations review the Catalog and address the vulnerabilities in their infrastructure.
CISA orders federal agencies to fix this vulnerability by February 13, 2025.
