CVE ID | Published | Description | Score | Severity |
---|---|---|---|---|
CGI implementation in Yaws web server versions 1.81 to 2.0.7 is vulnerable to OS command injection. | 9.8 |
Critical |
||
WebDAV implementation in Yaws web server versions 1.81 to 2.0.7 is vulnerable to XXE injection. | 9.8 |
Critical |
||
yaws before 2.0.4 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect CGI applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect a CGI application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. | 6.1 |
Medium |
||
Yaws 1.85 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. | 5 |
