A vulnerability classified as critical has been found in D-Link DIR-890L and DIR-806A1 up to 100CNb11/108B03. Affected is the function sub175C8 of the file /htdocs/soap.cgi. The manipulation leads to command injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. This vulnerability only affects products that are no longer supported by the maintainer.

D-Link DIR-890L FW1.10 A1 is vulnerable to Authentication bypass.

UNSUPPORTED WHEN ASSIGNED D-Link DIR-890L 1.20b01 allows attackers to execute arbitrary code due to the hardcoded option Wake-On-Lan for the parameter 'descriptor' at SetVirtualServerSettings.php.

The LAN-side Web-Configuration Interface has Stack-based Buffer Overflow vulnerability in the D-Link Wi-Fi router firmware DIR-890L DIR890LA1FW107b09.bin and previous versions. The function created at 0x17958 of /htdocs/cgibin will call sprintf without checking the length of strings in parameters given by HTTP header and can be controlled by users easily. The attackers can exploit the vulnerability to carry out arbitrary code by means of sending a specially constructed payload to port 49152.

D-Link DIR-859 routers before v1.07b03beta allow Unauthenticated Information Disclosure via the AUTHORIZEDGROUP=1%0a value, as demonstrated by vpnconfig.php.

Processing malformed SOAP messages when performing the HNAP Login action causes a buffer overflow in the stack in some D-Link DIR routers. The vulnerable XML fields within the SOAP body are: Action, Username, LoginPassword, and Captcha. The following products are affected: DIR-823, DIR-822, DIR-818L(W), DIR-895L, DIR-890L, DIR-885L, DIR-880L, DIR-868L, and DIR-850L.

An issue was discovered on D-Link DIR-890L with firmware 1.21B02beta01 and earlier, DIR-885L/R with firmware 1.21B03beta01 and earlier, and DIR-895L/R with firmware 1.21B04beta04 and earlier devices (all hardware revisions). Due to the predictability of the /docs/captcha(number).jpeg URI, being local to the network, but unauthenticated to the administrator's panel, an attacker can disclose the CAPTCHAs used by the access point and can elect to load the CAPTCHA of their choosing, leading to unauthorized login attempts to the access point.

Stack-based buffer overflow in dws/api/Login on D-Link DIR-850L B1 2.07 before 2.07WWB05, DIR-817 Ax, DIR-818LW Bx before 2.05b03beta03, DIR-822 C1 3.01 before 3.01WWb02, DIR-823 A1 1.00 before 1.00WWb05, DIR-895L A1 1.11 before 1.11WWb04, DIR-890L A1 1.09 before 1.09b14, DIR-885L A1 1.11 before 1.11WWb07, DIR-880L A1 1.07 before 1.07WWb08, DIR-868L B1 2.03 before 2.03WWb01, and DIR-868L C1 3.00 before 3.00WWb01 devices allows remote attackers to execute arbitrary code via a long session cookie.
