Acme » Mini Httpd : Security Vulnerabilities, CVEs,

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.

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.

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.

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 /.
