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 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.

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 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 through command line options, perhaps this issue should not be included in CVE. However, if there are some typical or recommended configurations that use htpasswd with sudo privileges, or common products that access htpasswd remotely, then perhaps it should be included.

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 command line options, perhaps this issue should not be included in CVE. However, if there are some typical or recommended configurations that use htpasswd with sudo privileges, or common products that access htpasswd remotely, then perhaps it should be included.

Cross-site scripting (XSS) vulnerability in cal_make.pl in ACME PerlCal 2.99.20 allows remote attackers to inject arbitrary web script or HTML via the p0 parameter.

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

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:").
