Vulnerabilidades

An unauthenticated stack-based buffer overflow vulnerability exists in thttpd in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when processing web request parameters in a specific request path. A remote attacker may exploit this vulnerability by…

An issue was discovered in sthttpd through 2.27.1. On systems where the strcpy function is implemented with memcpy, the de_dotdot function may cause a Denial-of-Service (daemon crash) due to overlapping memory ranges being passed to memcpy. This can triggered with an HTTP GET request for a crafted filename. NOTE: this…

thttpd 2007 has buffer underflow.

thttpd has a local DoS vulnerability via specially-crafted .htpasswd files

The htpasswd implementation of mini_httpd before v1.28 and of thttpd before v2.28 is affected by a buffer overflow that can be exploited remotely to perform code execution.

Heap-based Buffer Overflow in the de_dotdot function in libhttpd.c in sthttpd before 2.27.1 allows remote attackers to cause a denial of service (daemon crash) or possibly have unspecified other impact via a crafted filename.

thttpd.c in sthttpd before 2.26.4-r2 and thttpd 2.25b use world-readable permissions for /var/log/thttpd.log, which allows local users to obtain sensitive information by reading the file.

thttpd 2.25b0 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator.

thttpd before 2.25b-r6 in Gentoo Linux is started from the system root directory (/) by the Gentoo baselayout 1.12.6 package, which allows remote attackers to read arbitrary files.

thttpd on Debian GNU/Linux, and possibly other distributions, allows local users to create or touch arbitrary files via a symlink attack on the start_thttpd temporary file.

htpasswd, as used in Acme thttpd 2.25b and possibly other products such as Apache, might allow local users to gain privileges via shell metacharacters in a command line argument, which is used in a call to the system function. NOTE: since htpasswd is normally installed as a non-setuid program, and the exploit is…

Multiple buffer overflows in htpasswd, as used in Acme thttpd 2.25b, and possibly other products such as Apache, might allow local users to gain privileges via (1) a long command line argument and (2) a long line in a file. NOTE: since htpasswd is normally installed as a non-setuid program, and the exploit is through…

syslogtocern in Acme thttpd before 2.23 allows local users to write arbitrary files via a symlink attack on a temporary file.

Cross-site scripting (XSS) vulnerability in FREESCO 2.05, a modified version of thttpd, allows remote attackers to inject arbitrary web script or HTML via the test parameter.

Multiple directory traversal vulnerabilities in thttpd 2.07 beta 0.4, when running on Windows, allow remote attackers to read arbitrary files via a URL that contains (1) a hex-encoded backslash dot-dot sequence ("%5C..") or (2) a drive letter (such as "C:").

Buffer overflow in defang in libhttpd.c for thttpd 2.21 to 2.23b1 allows remote attackers to execute arbitrary code via requests that contain '<' or '>' characters, which trigger the overflow when the characters are expanded to "&lt;" and "&gt;" sequences.

Directory traversal vulnerability in thttpd, when using virtual hosting, allows remote attackers to read arbitrary files via .. (dot dot) sequences in the Host: header.

Cross-site scripting vulnerability in thttpd 2.20 and earlier allows remote attackers to execute arbitrary script via a URL to a nonexistent page, which causes thttpd to insert the script into a 404 error message.

Off-by-one buffer overflow in Basic Authentication in Acme Labs thttpd 1.95 through 2.20 allows remote attackers to cause a denial of service and possibly execute arbitrary code.

Acme Thttpd Secure Webserver before 2.22, with the chroot option enabled, allows remote attackers to view sensitive files under the document root (such as .htpasswd) via a GET request with a trailing /.

Directory traversal vulnerability in ssi CGI program in thttpd 2.19 and earlier allows remote attackers to read arbitrary files via a "%2e%2e" string, a variation of the .. (dot dot) attack.

Buffer overflow in Trivial HTTP (THTTPd) allows remote attackers to cause a denial of service or execute arbitrary commands via a long If-Modified-Since header.

thttpd HTTP server 2.03 and earlier allows remote attackers to read arbitrary files via a GET request with more than one leading / (slash) character in the filename.

Buffer overflow in thttpd HTTP server before 2.04-31 allows remote attackers to execute arbitrary commands via a long date string, which is not properly handled by the tdate_parse function.
