7.5CVE-2018-15505embedthisappweb+2
EPSS score
2.23%
An issue was discovered in Embedthis GoAhead before 4.0.1 and Appweb before 7.0.2. An HTTP POST request with a specially crafted "Host" header field may cause a NULL pointer dereference and thus cause a denial of service, as demonstrated by the lack of a trailing ']' character in an IPv6 address.
7.5CVE-2018-15504embedthisappweb+2
EPSS score
2.77%
An issue was discovered in Embedthis GoAhead before 4.0.1 and Appweb before 7.0.2. The server mishandles some HTTP request fields associated with time, which results in a NULL pointer dereference, as demonstrated by If-Modified-Since or If-Unmodified-Since with a month greater than 11.
8.1CVE-2018-8715embedthisappweb
EPSS score
22.79%
The Embedthis HTTP library, and Appweb versions before 7.0.3, have a logic flaw related to the authCondition function in http/httpLib.c. With a forged HTTP request, it is possible to bypass authentication for the form and digest login types.
9.8CVE-2021-41615embedthisgoahead
EPSS score
1.42%
websda.c in GoAhead WebServer 2.1.8 has insufficient nonce entropy because the nonce calculation relies on the hardcoded onceuponatimeinparadise value, which does not follow the secret-data guideline for HTTP Digest Access Authentication in RFC 7616 section 3.3 (or RFC 2617 section 3.2.1). NOTE: 2.1.8 is a version from 2003; however, the affected websda.c code appears in multiple derivative works that may be used in 2021. Recent GoAhead software is unaffected.
9.8CVE-2021-42342embedthisgoahead
EPSS score
59.46%
An issue was discovered in GoAhead 4.x and 5.x before 5.1.5. In the file upload filter, user form variables can be passed to CGI scripts without being prefixed with the CGI prefix. This permits tunneling untrusted environment variables into vulnerable CGI scripts.
9.8CVE-2021-43298embedthisgoahead
EPSS score
2.26%
The code that performs password matching when using 'Basic' HTTP authentication does not use a constant-time memcmp and has no rate-limiting. This means that an unauthenticated network attacker can brute-force the HTTP basic password, byte-by-byte, by recording the webserver's response time until the unauthorized (401) response.
7.5CVE-2021-33254embedthisappweb
EPSS score
1.52%
An issue was discovered in src/http/httpLib.c in EmbedThis Appweb Community Edition 8.2.1, allows attackers to cause a denial of service via the stream paramter to the parseUri function.
7.5CVE-2020-15689embedthisappweb
EPSS score
1.33%
Appweb before 7.2.2 and 8.x before 8.1.0, when built with CGI support, mishandles an HTTP request with a Range header that lacks an exact range. This may result in a NULL pointer dereference and cause a denial of service.
8.8CVE-2020-15688embedthisgoahead
EPSS score
4.04%
The HTTP Digest Authentication in the GoAhead web server before 5.1.2 does not completely protect against replay attacks. This allows an unauthenticated remote attacker to bypass authentication via capture-replay if TLS is not used to protect the underlying communication channel.
7.5CVE-2014-9707embedthisgoahead
EPSS score
28.24%
EmbedThis GoAhead 3.0.0 through 3.4.1 does not properly handle path segments starting with a . (dot), which allows remote attackers to conduct directory traversal attacks, cause a denial of service (heap-based buffer overflow and crash), or possibly execute arbitrary code via a crafted URI.
5CVE-2014-9708embedthisappweb+2
EPSS score
56.19%
Embedthis Appweb before 4.6.6 and 5.x before 5.2.1 allows remote attackers to cause a denial of service (NULL pointer dereference) via a Range header with an empty value, as demonstrated by "Range: x=,".
7.5CVE-2017-1000470embedthisgoahead_web_server
EPSS score
7.86%
EmbedThis GoAhead Webserver versions 4.0.0 and earlier is vulnerable to an integer overflow in the HTTP listener resulting in denial of service.
9.8CVE-2017-1000471embedthisgoahead
EPSS score
8.61%
EmbedThis GoAhead Webserver version 4.0.0 is vulnerable to a NULL pointer dereference in the CGI handler resulting in memory corruption or denial of service.
7.5CVE-2017-14149embedthisgoahead
EPSS score
5.79%
GoAhead 3.4.0 through 3.6.5 has a NULL Pointer Dereference in the websDecodeUrl function in http.c, leading to a crash for a "POST / HTTP/1.1" request.
8.1CVE-2017-17562embedthisgoahead+1KEV
EPSS score
97.13%
Embedthis GoAhead before 3.6.5 allows remote code execution if CGI is enabled and a CGI program is dynamically linked. This is a result of initializing the environment of forked CGI scripts using untrusted HTTP request parameters in the cgiHandler function in cgi.c. When combined with the glibc dynamic linker, this behaviour can be abused for remote code execution using special parameter names such as LD_PRELOAD. An attacker can POST their shared object payload in the body of the request, and reference it using /proc/self/fd/0.
9CVE-2017-5675embedthisgoahead
EPSS score
1.71%
A command-injection vulnerability exists in a web application on a custom-built GoAhead web server used on Foscam, Vstarcam, and multiple white-label IP camera models. The mail-sending form in the mail.htm page allows an attacker to inject a command into the receiver1 field in the form; it will be executed with root privileges.
9.8CVE-2017-5674embedthisgoahead
EPSS score
21.57%
A vulnerability in a custom-built GoAhead web server used on Foscam, Vstarcam, and multiple white-label IP camera models allows an attacker to craft a malformed HTTP ("GET system.ini HTTP/1.1\n\n" - note the lack of "/" in the path field of the request) request that will disclose the configuration file with the login password.
5.3CVE-2024-3186embedthisgoahead
EPSS score
0.45%
CWE-476 NULL Pointer Dereference vulnerability in the evalExpr() function of GoAhead Web Server (version <= 6.0.0) when compiled with the ME_GOAHEAD_JAVASCRIPT 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.
5.9CVE-2024-3184embedthisgoahead
EPSS score
0.48%
Multiple CWE-476 NULL Pointer Dereference vulnerabilities were found in GoAhead Web Server up to version 6.0.0 when compiled with the ME_GOAHEAD_REPLACE_MALLOC 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).
5.9CVE-2024-3187embedthisgoahead
EPSS score
0.50%
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 ME_GOAHEAD_JAVASCRIPT 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.
