Apache Tomcat 6.0.0 through 6.0.14, 5.5.0 through 5.5.25, and 4.1.0 through 4.1.36 does not properly handle (1) double quote (") characters or (2) %5C (encoded backslash) sequences in a cookie value, which might cause sensitive information such as session IDs to be leaked to remote attackers and enable session hijacking attacks. NOTE: this issue exists because of an incomplete fix for CVE-2007-3385.

The SingleSignOn Valve (org.apache.catalina.authenticator.SingleSignOn) in Apache Tomcat before 5.5.21 does not set the secure flag for the JSESSIONIDSSO cookie in an https session, which can cause the cookie to be sent in http requests and make it easier for remote attackers to capture this cookie.

The default catalina.policy in the JULI logging component in Apache Tomcat 5.5.9 through 5.5.25 and 6.0.0 through 6.0.15 does not restrict certain permissions for web applications, which allows attackers to modify logging configuration options and overwrite arbitrary files, as demonstrated by changing the (1) level, (2) directory, and (3) prefix attributes in the org.apache.juli.FileHandler handler.

Apache Tomcat 6.0.0 to 6.0.13, 5.5.0 to 5.5.24, 5.0.0 to 5.0.30, 4.1.0 to 4.1.36, and 3.3 to 3.3.2 treats single quotes ("'") as delimiters in cookies, which might cause sensitive information such as session IDs to be leaked and allow remote attackers to conduct session hijacking attacks.

Apache Tomcat 6.0.0 to 6.0.13, 5.5.0 to 5.5.24, 5.0.0 to 5.0.30, 4.1.0 to 4.1.36, and 3.3 to 3.3.2 does not properly handle the \" character sequence in a cookie value, which might cause sensitive information such as session IDs to be leaked to remote attackers and enable session hijacking attacks.

Cross-site scripting (XSS) vulnerability in the Host Manager Servlet for Apache Tomcat 6.0.0 to 6.0.13 and 5.5.0 to 5.5.24 allows remote attackers to inject arbitrary HTML and web script via crafted requests, as demonstrated using the aliases parameter to an html/add action.

Multiple cross-site scripting (XSS) vulnerabilities in certain JSP files in the examples web application in Apache Tomcat 4.0.0 through 4.0.6, 4.1.0 through 4.1.36, 5.0.0 through 5.0.30, 5.5.0 through 5.5.24, and 6.0.0 through 6.0.13 allow remote attackers to inject arbitrary web script or HTML via the portion of the URI after the ';' character, as demonstrated by a URI containing a "snp/snoop.jsp;" sequence.

Multiple cross-site scripting (XSS) vulnerabilities in the (1) Manager and (2) Host Manager web applications in Apache Tomcat 4.0.0 through 4.0.6, 4.1.0 through 4.1.36, 5.0.0 through 5.0.30, 5.5.0 through 5.5.24, and 6.0.0 through 6.0.13 allow remote authenticated users to inject arbitrary web script or HTML via a parameter name to manager/html/upload, and other unspecified vectors.

Cross-site scripting (XSS) vulnerability in implicit-objects.jsp in Apache Tomcat 5.0.0 through 5.0.30 and 5.5.0 through 5.5.17 allows remote attackers to inject arbitrary web script or HTML via certain header values.

Cross-site scripting (XSS) vulnerability in the calendar application example in Apache Tomcat 4.0.0 through 4.0.6, 4.1.0 through 4.1.31, 5.0.0 through 5.0.30, and 5.5.0 through 5.5.15 allows remote attackers to inject arbitrary web script or HTML via the time parameter to cal2.jsp and possibly unspecified other vectors. NOTE: this may be related to CVE-2006-0254.1.

The default SSL cipher configuration in Apache Tomcat 4.1.28 through 4.1.31, 5.0.0 through 5.0.30, and 5.5.0 through 5.5.17 uses certain insecure ciphers, including the anonymous cipher, which allows remote attackers to obtain sensitive information or have other, unspecified impacts.

Directory traversal vulnerability in Apache HTTP Server and Tomcat 5.x before 5.5.22 and 6.x before 6.0.10, when using certain proxy modules (mod_proxy, mod_rewrite, mod_jk), allows remote attackers to read arbitrary files via a .. (dot dot) sequence with combinations of (1) "/" (slash), (2) "\" (backslash), and (3) URL-encoded backslash (%5C) characters in the URL, which are valid separators in Tomcat but not in Apache.

Apache Tomcat 5 before 5.5.17 allows remote attackers to list directories via a semicolon (;) preceding a filename with a mapped extension, as demonstrated by URLs ending with /;index.jsp and /;help.do.

Apache Tomcat 5.5.0 to 5.5.11 allows remote attackers to cause a denial of service (CPU consumption) via a large number of simultaneous requests to list a web directory that has a large number of files.
