CVE-2016-1000108

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.

• Обновитесь до 2.0.3-2

CVE-2011-4350

Yaws 1.91 has a directory traversal vulnerability in the way certain URLs are processed. A remote authenticated user could use this flaw to obtain content of arbitrary local files via specially-crafted URL request.

CVE-2017-10974

Yaws 1.91 allows Unauthenticated Remote File Disclosure via HTTP Directory Traversal with /%5C../ to port 8080. NOTE: this CVE is only about use of an initial /%5C sequence to defeat traversal protection mechanisms; the initial /%5C sequence was apparently not discussed in earlier research on this product.

• Обновитесь до 1.91-2

CVE-2011-5025

Multiple cross-site scripting (XSS) vulnerabilities in the wiki application in Yaws 1.88 allow remote attackers to inject arbitrary web script or HTML via (1) the tag parameter to editTag.yaws, (2) the index parameter to showOldPage.yaws, (3) the node parameter to allRefsToMe.yaws, or (4) the text parameter to editPage.yaws.

• Обновитесь до 1.92-1

CVE-2009-4495

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.

CVE-2009-0751

Yaws before 1.80 allows remote attackers to cause a denial of service (memory consumption and crash) via a request with a large number of headers.
