CVE-2012-3499

TITLE

Apache HTTP Server Multiple cross-site scripting vulnerabilities

DESCRIPTION

Multiple cross-site scripting (XSS) vulnerabilities in the Apache HTTP Server 2.2.x before 2.2.24-dev and 2.4.x before 2.4.4 allow remote attackers to inject arbitrary web script or HTML via vectors involving hostnames and URIs in the (1) mod_imagemap, (2) mod_info, (3) mod_ldap, (4) mod_proxy_ftp, and (5) mod_status modules. An attacker may leverage these issues to execute arbitrary HTML and script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks. Apache HTTP Server versions prior to 2.4.4 are vulnerable. CVE-2012-3499 The modules mod_info, mod_status, mod_imagemap, mod_ldap, and mod_proxy_ftp did not properly escape hostnames and URIs in HTML output, causing cross site scripting vulnerabilities. CVE-2012-4558 Mod_proxy_balancer did not properly escape hostnames and URIs in its balancer-manager interface, causing a cross site scripting vulnerability. CVE-2013-1048 Hayawardh Vijayakumar noticed that the apache2ctl script created the lock directory in an unsafe manner, allowing a local attacker to gain elevated privileges via a symlink attack. For the stable distribution (squeeze), these problems have been fixed in version 2.2.16-6+squeeze11. For the testing distribution (wheezy), these problems will be fixed in version 2.2.22-13. For the unstable distribution (sid), these problems will be fixed in version 2.2.22-13. We recommend that you upgrade your apache2 packages. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: httpd security update Advisory ID: RHSA-2013:0815-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0815.html Issue date: 2013-05-13 CVE Names: CVE-2012-3499 CVE-2012-4558 CVE-2013-1862 ===================================================================== 1. Summary: Updated httpd packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 3. Cross-site scripting (XSS) flaws were found in the mod_proxy_balancer module's manager web interface. (CVE-2012-4558) It was found that mod_rewrite did not filter terminal escape sequences from its log file. If mod_rewrite was configured with the RewriteLog directive, a remote attacker could use specially-crafted HTTP requests to inject terminal escape sequences into the mod_rewrite log file. If a victim viewed the log file with a terminal emulator, it could result in arbitrary command execution with the privileges of that user. (CVE-2013-1862) Cross-site scripting (XSS) flaws were found in the mod_info, mod_status, mod_imagemap, mod_ldap, and mod_proxy_ftp modules. An attacker could possibly use these flaws to perform XSS attacks if they were able to make the victim's browser generate an HTTP request with a specially-crafted Host header. (CVE-2012-3499) All httpd users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon will be restarted automatically. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5.

(CVE-2012-3499) A session fixation flaw was found in the Tomcat FormAuthenticator module. During a narrow window of time, if a remote attacker sent requests while a user was logging in, it could possibly result in the attacker's requests being processed as if they were sent by the user. (CVE-2013-2067) A denial of service flaw was found in the way the Tomcat chunked transfer encoding input filter processed CRLF sequences. Chunked transfer encoding is enabled by default. (CVE-2012-3544) A flaw was found in the way the Tomcat 7 asynchronous context implementation performed request management in certain circumstances. If an application used AsyncListeners and threw RuntimeExceptions, Tomcat could send a reply that contains information from a different user's request, possibly leading to the disclosure of sensitive information. This issue only affected Tomcat 7. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ESA-2015-043: RSA\xae Validation Manager Security Update for Multiple Vulnerabilities EMC Identifier: ESA-2015-043 CVE Identifier: CVE-2014-3566, CVE-2014-0098, CVE-2014-0231, CVE-2014-0226, CVE-2013-1862, CVE-2012-3499, CVE-2015-0526, CVE-2013-2566 Severity Rating: CVSSv2 Base Score: See below for details Affected Products: RSA Validation Manager 3.2 prior to Build 201 Unaffected Products: RSA Validation Manager 3.2 Build 201 or above Summary: RSA Validation Manager (RVM) requires a security update to address potential multiple vulnerabilities.

This release serves as a replacement for Red Hat JBoss Enterprise Application Platform 6.1.0, and includes bug fixes and enhancements. Refer to the 6.1.1 Release Notes for information on the most significant of these changes, available shortly from https://access.redhat.com/site/documentation/ Security fixes: Cross-site scripting (XSS) flaws were found in the mod_info, mod_status, mod_imagemap, mod_ldap, and mod_proxy_ftp modules. (CVE-2012-4558) A flaw was found in the way the mod_dav module handled merge requests. An attacker could use this flaw to send a crafted merge request that contains URIs that are not configured for DAV, causing the httpd child process to crash. (CVE-2013-1896) A flaw was found in the way Apache Santuario XML Security for Java validated XML signatures. Santuario allowed a signature to specify an arbitrary canonicalization algorithm, which would be applied to the SignedInfo XML fragment. A remote attacker could exploit this to spoof an XML signature via a specially-crafted XML signature block. (CVE-2013-1862) The data file used by PicketBox Vault to store encrypted passwords contains a copy of its own admin key. The file is encrypted using only this admin key, not the corresponding JKS key. A local attacker with permission to read the vault data file could read the admin key from the file, and use it to decrypt the file and read the stored passwords in clear text. This could be exploited to read diagnostic information (information disclosure) and attain limited remote code execution. Refer to the Solution section for further details. The JBoss server process must be restarted for the update to take effect. On update, the configuration files that have been locally modified will not be updated. The updated version of such files will be stored as the rpmnew files. Make sure to locate any such files after the update and merge any changes manually. ============================================================================ Ubuntu Security Notice USN-1765-1 March 18, 2013 apache2 vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.10 - Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS Summary: Several security issues were fixed in the Apache HTTP Server. 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. A remote attacker could use this issue to cause the server to stop responding, resulting in a denial of service. This issue only applied to Ubuntu 8.04 LTS, Ubuntu 10.04 LTS and Ubuntu 11.10. (CVE-2012-4557) It was discovered that the apache2ctl script shipped in Ubuntu packages incorrectly created the lock directory. A local attacker could possibly use this issue to gain privileges. The symlink protections in Ubuntu 11.10 and later should reduce this vulnerability to a denial of service. (CVE-2013-1048) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.10: apache2.2-common 2.2.22-6ubuntu2.2 Ubuntu 12.04 LTS: apache2.2-common 2.2.22-1ubuntu1.3 Ubuntu 11.10: apache2.2-common 2.2.20-1ubuntu1.4 Ubuntu 10.04 LTS: apache2.2-common 2.2.14-5ubuntu8.11 Ubuntu 8.04 LTS: apache2.2-common 2.2.8-1ubuntu0.25 In general, a standard system update will make all the necessary changes
