SonicWall patched two recently exploited zero-day vulnerabilities in its SMA 1000 Series secure remote access appliances which may have been chained for unauthenticated remote code execution.Key takeawaysCVE-2026-15409 and CVE-2026-15410 are a pair of exploited vulnerabilities that may have been chained together to allow for code execution on SonicWall SMA1000 series appliances. Zero-day exploitation of these vulnerabilities has been observed and confirmed by SonicWall. Patches and indicators of compromise are available and urgent patching is recommended.BackgroundSonicWall's Secure Mobile Access (SMA) 1000 Series appliances are enterprise-grade SSL VPN gateways which serve as the front door to organizational networks. The SMA series models sit at the edge of the network, internet-facing by design. Because SMA 1000 appliances aggregate remote access credentials and sit directly on the internet, they represent high-value targets for attackers. A compromise at the appliance level can yield administrator credentials, VPN session tokens, and detailed knowledge of the internal network architecture sitting behind the gateway.On July 14, SonicWall disclosed two vulnerabilities that are being exploited together in the wild:CVEDescriptionCVSSv3CVE-2026-15409SonicWall SMA 1000 server-side request forgery (SSRF) vulnerability10CVE-2026-15410SonicWall SMA 1000 remote code execution vulnerability (RCE)7.2While the advisory does not specify if they were exploited in tandem, together they form a fully remote, unauthenticated path to arbitrary OS command execution on affected appliances.AnalysisCVE-2026-15409 is a SSRF vulnerability affecting the SMA 1000 Workplace interface. This flaw allows a remote, unauthenticated attacker to make network requests to locations of the attacker's choosing. In practice, SSRF on an internet-facing appliance can serve as a pivot, allowing an attacker to probe internal services, relay authentication material, or reach the AMC in a way that...

OverviewOn July 14, 2026, SonicWall published a security advisory addressing two vulnerabilities affecting SMA1000 Series remote access appliances, including the critical server-side request forgery (SSRF) vulnerability CVE-2026-15409 (CVSS 10.0) and the high-severity code injection vulnerability CVE-2026-15410. The advisory urges customers to immediately apply the latest platform hotfix releases.Successful exploitation of CVE-2026-15409 permits an unauthenticated attacker to open a websocket-based tunnel to arbitrary localhost-only services, while CVE-2026-15410 is a local privilege escalation that permits an attacker with access to an internal service listening on port 8188 on localhost to execute arbitrary operating system commands as root via a malicious path traversal-based remove_hotfix workflow.Both vulnerabilities are being actively exploited in the wild. Prior to SonicWall’s official vulnerability disclosure, Rapid7’s Managed Detection and Response team observed active, targeted zero-day exploitation of internet-facing SMA 1000-series appliances. In the SonicWall advisory, exploitation in the wild was noted, and both CVE-2026-15409 and CVE-2026-15410 have been added to CISA's Known Exploited Vulnerabilities (KEV) catalog. Given the confirmed exploitation activity and the critical unauthenticated impact of the vulnerabilities, organizations should prioritize remediation of SMA1000 appliances on an emergency basis. A Python proof-of-concept for CVE-2026-15409 is available here for exposure validation, and a Metasploit module for the chain is in development.Affected products include SonicWall SMA1000 Series models 6210, 7210, and 8200v running:12.4.3-0324512.4.3-0338712.4.3-03434 (platform-hotfix)12.5.0-0228312.5.0-0262412.5.0-02800 (platform-hotfix)These vulnerabilities do not affect SSL VPN functionality on SonicWall firewalls or the SMA 100 Series product line.Technical overviewThe primary vulnerability is in a websocket proxy feature, accessed via the...

All CISA Advisories · Jul 14, 2026

CISA has added four new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2026-15409 SonicWall SMA1000 Appliances Server-Side Request Forgery Vulnerability CVE-2026-15410 SonicWall SMA1000 Appliances Code Injection Vulnerability CVE-2026-56155 Microsoft Active Directory Federation Services Insufficient Granularity of Access Control Vulnerability CVE-2026-56164 Microsoft SharePoint Server Missing Authentication for Critical Function Vulnerability These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied. While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria. Aware of an exploited vulnerability not currently listed in the KEV Catalog? Submit it for potential addition through CISA’s KEV Nomination Form. Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.
