Main_Analysis_Content.asp in /apply.cgi on ASUS RT-AC66U, RT-AC68U, RT-AC86U, RT-AC88U, RT-AC1900, RT-AC2900, and RT-AC3100 devices before 3.0.0.4.384_10007; RT-N18U devices before 3.0.0.4.382.39935; RT-AC87U and RT-AC3200 devices before 3.0.0.4.382.50010; and RT-AC5300 devices before 3.0.0.4.384.20287 allows OS command injection via the pingCNT and destIP fields of the SystemCmd variable.
Improper administrator IP validation after his login in the HTTPd server in all current versions (<= 3.0.0.4.380.7743) of Asus asuswrt allows an unauthorized user to execute any action knowing administrator session token by using a specific User-Agent string.
Highly predictable session tokens in the HTTPd server in all current versions (<= 3.0.0.4.380.7743) of Asus asuswrt allow gaining administrative router access.
Multiple buffer overflow vulnerabilities exist in the HTTPd server in Asus asuswrt version <=3.0.0.4.376.X. All have been fixed in version 3.0.0.4.378, but this vulnerability was not previously disclosed. Some end-of-life routers have this version as the newest and thus are vulnerable at this time. This vulnerability allows for RCE with administrator rights when the administrator visits several pages.
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.
An issue was discovered in AsusWRT before 3.0.0.4.384_10007. In the handle_request function in router/httpd/httpd.c, processing of POST requests continues even if authentication fails.
