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.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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. (CVE-2007-0450)

According to its self-reported version number, the Apache Tomcat instance listening on the remote host is prior to 6.0.10. It is, therefore, affected by the following vulnerability :

  - A directory traversal vulnerability exists in Tomcat due to     improper handling of certain path delimiters when behind a     proxy. An unauthenticated, remote attacker can exploit this,     by sending a URI that contains directory traversal characters,     to disclose the contents of files located outside of the     server's restricted path.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2007-0327 advisory.

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Some JSPs within the 'examples' web application did not escape user provided data. If the JSP examples were accessible, this flaw could allow a remote attacker to perform cross-site scripting attacks (CVE-2007-2449).

Note: it is recommended the 'examples' web application not be installed on a production system.

The Manager and Host Manager web applications did not escape user provided data. If a user is logged in to the Manager or Host Manager web application, an attacker could perform a cross-site scripting attack (CVE-2007-2450).

Tomcat was found to accept multiple content-length headers in a request. This could allow attackers to poison a web-cache, bypass web application firewall protection, or conduct cross-site scripting attacks. (CVE-2005-2090)

Tomcat permitted various characters as path delimiters. If Tomcat was used behind certain proxies and configured to only proxy some contexts, an attacker could construct an HTTP request to work around the context restriction and potentially access non-proxied content.
(CVE-2007-0450)

The implict-objects.jsp file distributed in the examples webapp displayed a number of unfiltered header values. If the JSP examples were accessible, this flaw could allow a remote attacker to perform cross-site scripting attacks. (CVE-2006-7195)

According to its self-reported version number, the instance of Apache Tomcat 4.x listening on the remote host is prior to 4.1.36. It is, therefore, affected by the following vulnerabilities :

  - Requests containing multiple 'content-length' headers     are not rejected as invalid. This error can allow     web-cache poisoning, cross-site scripting attacks and     information disclosure. (CVE-2005-2090)

  - An input sanitization error exists that can allow     disclosure of sensitive information via directory     traversal. This vulnerability is exposed when the     server is configured to use the 'Proxy' module.
    (CVE-2007-0450)

  - 'Accept-Language' headers are not validated properly,     which can allow cross-site scripting attacks.
    (CVE-2007-1358)

Tomcat is a servlet container for Java Servlet and JavaServer Pages technologies.

It was reported Tomcat did not properly handle the following character sequence in a cookie: \' (a backslash followed by a double-quote). It was possible remote attackers could use this failure to obtain sensitive information, such as session IDs, for session hijacking attacks (CVE-2007-3385).

Tomcat was found treating single quote characters -- ' -- as delimiters in cookies. This could allow remote attackers to obtain sensitive information, such as session IDs, for session hijacking attacks (CVE-2007-3382).

The default Tomcat configuration permitted the use of insecure SSL cipher suites including the anonymous cipher suite. (CVE-2007-1858)

Tomcat permitted various characters as path delimiters. If Tomcat was used behind certain proxies and configured to only proxy some contexts, an attacker could construct an HTTP request to work around the context restriction and potentially access non-proxied content.
(CVE-2007-0450)

Directory listings were enabled by default in Tomcat. Information stored unprotected under the document root was visible to anyone if the administrator did not disable directory listings. (CVE-2006-3835)

It was found that generating listings of large directories was CPU intensive. An attacker could make repeated requests to obtain a directory listing of any large directory, leading to a denial of service. (CVE-2005-3510)

Tomcat was found to accept multiple content-length headers in a request. This could allow attackers to poison a web-cache, bypass web application firewall protection, or conduct cross-site scripting attacks. (CVE-2005-2090)

Users should upgrade to these erratum packages which contain an update to Tomcat that resolves these issues, and add the tyrex and jakarta-commons-pool packages which are required dependencies of the new Tomcat version.

The remote web server proxies certain requests to an Apache Tomcat server and allows directory traversal attacks due to Tomcat allowing '/', '\', and '%5c' characters as directory separators. 

By sending a specially crafted request, it is possible for an attacker to break out of the given context and access web applications that may not otherwise be proxied to the Tomcat web server.

Updated VirtualCenter fixes the following application vulnerabilities

a. Tomcat Server Security Update This release of VirtualCenter Server updates the Tomcat Server package from 5.5.17 to 5.5.25, which addresses multiple security issues that existed in the earlier releases of Tomcat Server.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2005-2090, CVE-2006-7195, and CVE-2007-0450 to these issues.

b. JRE Security Update This release of VirtualCenter Server updates the JRE package from 1.5.0_7 to 1.5.0_12, which addresses a security issue that existed in the earlier release of JRE.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-3004 to this issue.

NOTE: These vulnerabilities can be exploited remotely only if the       attacker has access to the service console network.

      Security best practices provided by VMware recommend that the       service console be isolated from the VM network. Please see       http://www.vmware.com/resources/techresources/726 for more       information on VMware security best practices.

A number of vulnerabilities were found in Tomcat :

A directory traversal vulnerability, when using certain proxy modules, allows a remote attacker to read arbitrary files via a .. (dot dot) sequence with various slash, backslash, or url-encoded backslash characters (CVE-2007-0450; affects Mandriva Linux 2007.1 only).

Multiple cross-site scripting vulnerabilities in certain JSP files allow remote attackers to inject arbitrary web script or HTML (CVE-2007-2449).

Multiple cross-site scripting vulnerabilities in the Manager and Host Manager web applications allow remote authenticated users to inject arbitrary web script or HTML (CVE-2007-2450).

Tomcat treated single quotes as delimiters in cookies, which could cause sensitive information such as session IDs to be leaked and allow remote attackers to conduct session hijacking attacks (CVE-2007-3382).

Tomcat did not properly handle the ' character sequence in a cookie value, which could cause sensitive information such as session IDs to be leaked and allow remote attackers to conduct session hijacking attacks (CVE-2007-3385).

A cross-site scripting vulnerability in the Host Manager servlet allowed remote attackers to inject arbitrary HTML and web script via crafted attacks (CVE-2007-3386).

Finally, an absolute path traversal vulnerability, under certain configurations, allows remote authenticated users to read arbitrary files via a WebDAV write request that specifies an entity with a SYSTEM tag (CVE-2007-5461).

The updated packages have been patched to correct these issues.

Certain characters of the URL were not properly filtered. This allowed directory reverse traversal attacks to access the web-root of tomcat.
(CVE-2007-0450)

The remote host is running a version of Mac OS X 10.4 or 10.3 which does not have the security update 2007-007 applied. 

This update contains several security fixes for the following programs :

Users should upgrade to these erratum packages which contain an update to Tomcat that resolves these issues. Updated jakarta-commons-modeler packages are also included which correct a bug when used with Tomcat 5.5.23.

The remote host is affected by the vulnerability described in GLSA-200705-03 (Tomcat: Information disclosure)

    Tomcat allows special characters like slash, backslash or URL-encoded     backslash as a separator, while Apache does not.
  Impact :

    A remote attacker could send a specially crafted URL to the vulnerable     Tomcat server, possibly resulting in a directory traversal and read     access to arbitrary files with the privileges of the user running     Tomcat. Note that this vulnerability can only be exploited when using     apache proxy modules like mod_proxy, mod_rewrite or mod_jk.
  Workaround :

    There is no known workaround at this time.

According to its self-reported version number, the Apache Tomcat instance listening on the remote host is prior to 6.0.10. It is, therefore, affected by the following vulnerability :

- A directory traversal vulnerability exists in Tomcat due to improper handling of certain path delimiters when behind a proxy. An unauthenticated, remote attacker can exploit this, by sending a URI that contains directory traversal characters, to disclose the contents of files located outside of the server's restricted path.
