What is CVE-2026-15410?

Post-authentication improper control of generation of code ('Code Injection') vulnerability has been identified in the SMA1000 Appliance Management Console (AMC) which in specific conditions could potentially enable a remote authenticated attacker as administrator to execute arbitrary OS commands.

Technical Analysis

Weakness Classification

This vulnerability is classified as CWE-94, Code Injection. The application allows user input to be interpreted as code, giving an attacker the ability to execute arbitrary code within the application context.

Attack Vector Breakdown

  • Attack Vector: Network
  • Attack Complexity: Low
  • Privileges Required: High
  • User Interaction: None
  • Scope: Unchanged
  • Confidentiality: High
  • Integrity: High
  • Availability: High

Impact Analysis

This vulnerability is exploitable over the network, meaning any system reachable via the internet or internal network is potentially at risk without physical access. The attack complexity is low, meaning exploitation does not depend on specialized conditions or race windows. Successful exploitation can result in full confidentiality breach (complete data disclosure), complete integrity compromise (data modification or code execution), total availability loss (denial of service). The application allows user input to be interpreted as code, giving an attacker the ability to execute arbitrary code within the application context.

Exploitation Probability (EPSS): 76.3% chance of exploitation in the next 30 days (99th percentile). This places the vulnerability in the highest risk tier, immediate action is critical.

Is CVE-2026-15410 being exploited?

Yes. CVE-2026-15410 is listed in CISA's Known Exploited Vulnerabilities (KEV) catalog, restricted to CVEs with confirmed active exploitation in the wild. CISA added this vulnerability on 2026-07-14. Inclusion in KEV triggers the patching mandate under BOD 22-01 for U.S. federal civilian agencies, with a remediation deadline of 2026-07-17.

How to fix CVE-2026-15410

Apply the security update issued by SonicWall for SMA1000 Appliances. Check the SonicWall Security Advisories page for the specific patch or update. If an immediate patch is not possible, consult the vendor advisory for mitigation guidance, restrict network exposure of the affected service, and monitor logs for indicators of exploitation. CISA's Known Exploited Vulnerabilities catalog requires U.S. federal agencies to remediate this vulnerability by the due date shown below under Binding Operational Directive 22-01. Private organizations should treat KEV entries as priority-one patches because active exploitation has been confirmed in the wild.
