D-Link DWR-912 FIRMWARE

An issue was discovered on D-Link DWR-116 through 1.06, DIR-140L through 1.02, DIR-640L through 1.02, DWR-512 through 2.02, DWR-712 through 2.02, DWR-912 through 2.02, DWR-921 through 2.02, and DWR-111 through 1.01 devices. The administrative password is stored in plaintext in the /tmp/csman/0 file. An attacker having a directory traversal (or LFI) can easily get full router access.

An issue was discovered on D-Link DWR-116 through 1.06, DWR-512 through 2.02, DWR-712 through 2.02, DWR-912 through 2.02, DWR-921 through 2.02, and DWR-111 through 1.01 devices. An authenticated attacker may execute arbitrary code by injecting the shell command into the chkisg.htm page Sip parameter. This allows for full control over the device internals.

Directory traversal vulnerability in the web interface on D-Link DWR-116 through 1.06, DIR-140L through 1.02, DIR-640L through 1.02, DWR-512 through 2.02, DWR-712 through 2.02, DWR-912 through 2.02, DWR-921 through 2.02, and DWR-111 through 1.01 devices allows remote attackers to read arbitrary files via a /.. or // after "GET /uir" in an HTTP request. NOTE: this vulnerability exists because of an incorrect fix for CVE-2017-6190.
