Acme LabsCVEs & Vulnerabilities
13 CVEs affecting Acme Labs products, tracked from the National Vulnerability Database, with CVSS/EPSS scores and exploitation status.
Most Affected Products
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.
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.
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.
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:").
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.
Acme.Serve 1.7, as used in Cisco Secure ACS Unix and possibly other products, allows remote attackers to read arbitrary files by prepending several / (slash) characters to the URI.
Directory traversal vulnerability in cal_make.pl in PerlCal allows remote attackers to read arbitrary files via a .. (dot dot) in the p0 parameter.
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.
