Denial of Service via HTTP Header Parsing in ACME mini_httpd

An issue in ACME mini_httpd 1.30 and prior allows a remote attacker to cause a denial of service via the HTTP request header parser in the handle_request() function

mini_httpd 1.19 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 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.

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.

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 /.

Acme mini_httpd before 1.16 allows remote attackers to view sensitive files under the document root (such as .htpasswd) via a GET request with a trailing /.

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.

mini_httpd 1.21 and earlier allows remote attackers to obtain sensitive information from process memory via an HTTP request with a long protocol string, which triggers an incorrect response size calculation and an out-of-bounds read.

Buffer overflow in ACME micro_httpd, as used in D-Link DSL2750U and DSL2740U and NetGear WGR614 and MR-ADSL-DG834 routers allows remote attackers to cause a denial of service (crash) via a long string in the URI in a GET request.

micro_httpd on the RCA DCM425 cable modem allows remote attackers to cause a denial of service (device reboot) via a long string to TCP port 80.

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.

ACME Ultra Mini HTTPd HTTP GET Request denial of service

A vulnerability was found in ACME Ultra Mini HTTPd 1.21. It has been classified as problematic. This affects an unknown part of the component HTTP GET Request Handler. The manipulation leads to denial of service. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-249819.

ACME mini_httpd before 1.30 lets remote users read arbitrary 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.

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

thttpd 2007 has buffer underflow.
