the working directory. An attacker could use this flaw to read or write
files outside of the intended working directory. (CVE-2010-3718)

It was discovered that Tomcat did not properly escape certain parameters in
the Manager application which could result in browsers becoming vulnerable
to cross-site scripting attacks when processing the output. With cross-site
scripting vulnerabilities, if a user were tricked into viewing server
output during a crafted server request, a remote attacker could exploit
this to modify the contents, or steal confidential data (such as
passwords), within the same domain. (CVE-2011-0013)

It was discovered that Tomcat incorrectly enforced the maxHttpHeaderSize
limit in certain configurations. A remote attacker could use this flaw to
cause Tomcat to consume all available memory, resulting in a denial of
service. (CVE-2011-0534)");
