The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information.\n\n## Affected\n\n- `adaptive_security_appliance < 9.6.4.31`\n- `adaptive_security_appliance_software >= 9.7, < 9.8.4.9`\n- `adaptive_security_appliance_software >= 9.9, < 9.9.2.56`\n- `adaptive_security_appliance_software >= 9.10, < 9.10.1.30`\n- `adaptive_security_appliance_software >= 9.12, < 9.12.2.9`\n- `adaptive_security_appliance_software >= 9.13, < 9.13.1`\n- `secure_firewall_threat_defense < 6.2.3.15`\n- `secure_firewall_threat_defense >= 6.3.0, < 6.3.0.5`\n- `secure_firewall_threat_defense >= 6.4.0, < 6.4.0.6`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `adaptive_security_appliance 9.6.4.31`\n- `adaptive_security_appliance_software 9.13.1`\n- `secure_firewall_threat_defense 6.4.0.6`","depth":"sunlit","depthScore":34,"depthScoreParts":{"impact":33.6,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
