A vulnerability was detected in D-Link DIR-816 1.10CNB05. Affected by this vulnerability is an unknown functionality of the file /goform/form2Wl5BasicSetup.cgi of the component goahead. Performing a manipulation of the argument pskValue results in stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit is now public and may be used. This vulnerability only affects products that are no longer supported by the maintainer.

Multiple CWE-476 NULL Pointer Dereference vulnerabilities were found in GoAhead Web Server up to version 6.0.0 when compiled with the MEGOAHEADREPLACEMALLOC flag. Without a memory notifier for allocation failures, remote attackers can exploit these vulnerabilities by sending malicious requests, leading to a crash and Denial of Service (DoS).

CWE-476 NULL Pointer Dereference vulnerability in the evalExpr() function of GoAhead Web Server (version <= 6.0.0) when compiled with the MEGOAHEADJAVASCRIPT flag. This vulnerability allows a remote attacker with the privileges to modify JavaScript template (JST) files to trigger a crash and cause a Denial of Service (DoS) by providing malicious templates.

This issue tracks two CWE-416 Use After Free (UAF) and one CWE-415 Double Free vulnerabilities in Goahead versions <= 6.0.0. These are caused by JST values not being nulled when freed during parsing of JST templates. If the MEGOAHEADJAVASCRIPT flag is enabled, a remote attacker with the privileges to modify JavaScript template (JST) files could exploit this by providing malicious templates. This may lead to memory corruption, potentially causing a Denial of Service (DoS) or, in rare cases, code execution, though the latter is highly context-dependent.

webs.c in GoAhead WebServer before 2.1.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an HTTP POST request that contains a Content-Length header but no body data.

The security handler in GoAhead WebServer before 2.1.1 allows remote attackers to bypass authentication and obtain access to protected web content via "an extra slash in a URL," a different vulnerability than CVE-2002-1603.

GoAhead WebServer allows remote attackers to cause a denial of service (daemon outage) via partial HTTP requests, as demonstrated by Slowloris.

Unspecified vulnerability in GoAhead WebServer before 2.1.4 allows remote attackers to cause "incorrect behavior" via unknown "malicious code," related to incorrect use of the socketInputBuffered function by sockGen.c.

GoAhead WebServer before 2.1.1 allows remote attackers to cause a denial of service (CPU consumption) by performing a socket disconnect to terminate a request before it has been fully processed by the server.

GoAhead WebServer before 2.1.6 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an invalid URL, related to the websSafeUrl function.

webs.c in GoAhead WebServer before 2.1.4 allows remote attackers to cause a denial of service (daemon crash) via an HTTP POST request that contains a negative integer in the Content-Length header.

GoAhead WebServer before 2.1.5 on Windows 95, 98, and ME allows remote attackers to cause a denial of service (daemon crash) via an HTTP request with a (1) con, (2) nul, (3) clock$, or (4) config$ device name in a path component, different vectors than CVE-2001-0385.

Multiple cross-site scripting (XSS) vulnerabilities in GoAhead Webserver 2.18 allow remote attackers to inject arbitrary web script or HTML via (1) the group parameter to goform/AddGroup, related to addgroup.asp; (2) the url parameter to goform/AddAccessLimit, related to addlimit.asp; or the (3) user (aka User ID) or (4) group parameter to goform/AddUser, related to adduser.asp.

An issue was discovered on Wireless IP Camera (P2P) WIFICAM cameras. There is Command Injection in the setftp.cgi script via shell metacharacters in the pwd variable, as demonstrated by a setftp.cgi?svr=192.168.1.1&port=21&user=ftp URI.
