ID CVE-2011-1921
Summary The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion 1.5.x and 1.6.x before 1.6.17, when the SVNPathAuthz short_circuit option is disabled, does not properly enforce permissions for files that had been publicly readable in the past, which allows remote attackers to obtain sensitive information via a replay REPORT operation.

Impact:
Exploitability:
CWE CWE-264
CAPEC
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

Upstream acknowledges Joe Schaefer of the Apache Software Foundation as the original reporter of CVE-2011-1752; Ivan Zhakov of VisualSVN as the original reporter of CVE-2011-1783; and Kamesh Jayachandran of CollabNet, Inc. as the original reporter of CVE-2011-1921. The following bugs are also fixed in this release : - make 'blame -g' more efficient on with large mergeinfo - preserve log message with a non-zero editor exit - fix FSFS cache performance on 64-bit platforms - make svn cleanup tolerate obstructed directories - fix deadlock in multithreaded servers serving FSFS repositories - detect very occasional corruption and abort commit - fixed: file externals cause non-inheritable mergeinfo - fixed: file externals cause mixed-revision working copies - fixed: write-through proxy could direcly commit to slave - detect a particular corruption condition in FSFS - improve error message when clients refer to unkown revisions - bugfixes and optimizations to the DAV mirroring code - fixed: locked and deleted file causes tree conflict - fixed: update touches locked file with svn:keywords property - fix svnsync handling of directory copyfrom - fix 'log -g' excessive duplicate output - fix svnsync copyfrom handling bug with BDB - server-side validation of svn:mergeinfo syntax during commit Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description From Red Hat Security Advisory 2011:0862 : Updated subversion packages that fix three 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. Subversion (SVN) is a concurrent version control system which enables one or more users to collaborate in developing and maintaining a hierarchy of files and directories while keeping a history of all changes. The mod_dav_svn module is used with the Apache HTTP Server to allow access to Subversion repositories via HTTP. An infinite loop flaw was found in the way the mod_dav_svn module processed certain data sets. If the SVNPathAuthz directive was set to 'short_circuit', and path-based access control for files and directories was enabled, a malicious, remote user could use this flaw to cause the httpd process serving the request to consume an excessive amount of system memory. (CVE-2011-1783) A NULL pointer dereference flaw was found in the way the mod_dav_svn module processed requests submitted against the URL of a baselined resource. A malicious, remote user could use this flaw to cause the httpd process serving the request to crash. (CVE-2011-1752) An information disclosure flaw was found in the way the mod_dav_svn module processed certain URLs when path-based access control for files and directories was enabled. A malicious, remote user could possibly use this flaw to access certain files in a repository that would otherwise not be accessible to them. Note: This vulnerability cannot be triggered if the SVNPathAuthz directive is set to 'short_circuit'. (CVE-2011-1921) Red Hat would like to thank the Apache Subversion project for reporting these issues. Upstream acknowledges Joe Schaefer of the Apache Software Foundation as the original reporter of CVE-2011-1752; Ivan Zhakov of VisualSVN as the original reporter of CVE-2011-1783; and Kamesh Jayachandran of CollabNet, Inc. as the original reporter of CVE-2011-1921. All Subversion users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, you must restart the httpd daemon, if you are using mod_dav_svn, for the update to take effect.

description The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion 1.5.x and 1.6.x before 1.6.17, when the SVNPathAuthz short_circuit option is disabled, does not properly enforce permissions for files that had been publicly readable in the past, which allows remote attackers to obtain sensitive information via a replay REPORT operation.
