ASUS Router - Upload arbitrary firmware

Certain models of ASUS routers have an arbitrary firmware upload vulnerability. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary system commands on the device.

Main_Analysis_Content.asp in ASUS DSL-N12E_C1 1.1.2.3_345 is prone to Authenticated Remote Command Execution, which allows a remote attacker to execute arbitrary OS commands via service parameters, such as shell metacharacters in the destIP parameter of a cmdMethod=ping request.

Multiple XML external entity (XXE) vulnerabilities in the AiCloud feature on ASUS DSL-AC51, DSL-AC52U, DSL-AC55U, DSL-N55U C1, DSL-N55U D1, DSL-AC56U, DSL-N10_C1, DSL-N12U C1, DSL-N12E C1, DSL-N14U, DSL-N14U-B1, DSL-N16, DSL-N16U, DSL-N17U, DSL-N66U, and DSL-AC750 routers allow remote authenticated users to read arbitrary files via a crafted DTD in (1) an UPDATEACCOUNT or (2) a PROPFIND request.

ASUS DSL-AC51, DSL-AC52U, DSL-AC55U, DSL-N55U C1, DSL-N55U D1, DSL-AC56U, DSL-N10_C1, DSL-N12U C1, DSL-N12E C1, DSL-N14U, DSL-N14U-B1, DSL-N16, DSL-N16U, DSL-N17U, DSL-N66U, and DSL-AC750 routers allow remote attackers to change passwords of arbitrary users via the http_passwd parameter to mod_login.asp.
