CVE-2018-17022: ASUS Gt-AC5300 Firmware

High severity, CVSS 7.2. EPSS: 2.2% chance of exploitation in the next 30 days.

Stack-based buffer overflow on the ASUS GT-AC5300 router through 3.0.0.4.384_32738 allows remote attackers to cause a denial of service (device crash) or possibly have unspecified other impact by setting a long sh_path0 value and then sending an appGet.cgi?hook=select_list("Storage_x_SharedPath") request, because ej_select_list in router/httpd/web.c uses strcpy.

Affected products

• ASUS Gt-AC5300 Firmware: up to and including 3.0.0.4.384_32738
