UNKNOWN Summary
The move_uploaded_file implementation in ext/standard/basic_functions.c in PHP before 5.4.39, 5.5.x before 5.5.23, and 5.6.x before 5.6.7 truncates a pathname upon encountering a \x00 character, which allows remote attackers to bypass intended extension restrictions and create files with unexpected names via a crafted second argument. NOTE: this vulnerability exists because of an incomplete fix for CVE-2006-7243.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (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.

description | PHP任意文件上传漏洞(CVE-2015-2348)。通常情况下,php的开发者会对文件名后缀、文件类型(Content-Type)、Mime type、文件大小等进行检查来限制恶意php脚本的上传,但是攻击者可以利用该漏洞绕过这些限制,直接上传恶意的文件。 ### 漏洞详情 该漏洞存在于php的move_uploaded_file()函数中,这个函数一般在上传文件时被使用,用途是将上传的文件移动到新位置。 ``` move_uploaded_file ( string $filename , string $destination ) ``` 这次的漏洞就出现在$destination这个参数中,这个参数代表的是上传文件移动的最终目的地址。如果$destination变量是从用户$_GET或$_POST中获得的并且我们可控,那么我们可以利用空字符\x00来截断后面的拓展名,从而造成任意文件上传。 ### 漏洞利用演示 我们利用DVWA的high难度来演示,首先我们把move_uploaded_file()函数的第二个参数改成我们可控的$_POST['xxname']。 ``` <?php if (isset($_POST['Upload'])) { $target_path = DVWA_WEB_PAGE_TO_ROOT."hackable/uploads/"; $target_path = $target_path . basename($_FILES['uploaded']['name']); $uploaded_name = $_FILES['uploaded']['name']; $uploaded_ext = substr($uploaded_name, strrpos($uploaded_name, '.') + 1); $uploaded_size = $_FILES['uploaded']['size']; if (($uploaded_ext == "jpg" || $uploaded_ext == "JPG" || $uploaded_ext == "jpeg" || $uploaded_ext == "JPEG") && ($uploaded_size < 100000)){ if(!move_uploaded_file($_FILES['uploaded']['tmp_name'], $_POST['xxname'])) { $html .= '<pre>'; $html .= 'Your image was not uploaded.'; $html .= '</pre>'; } else { $html .= '<pre>'; $html .= $target_path . ' succesfully uploaded!'; $html .= '</pre>'; } } else{ $html .= '<pre>'; $html .= 'Your image was not uploaded.'; $html .= '</pre>'; } } ?> ```  然后上传文件,这里把POST的xxname参数利用空字符进行截断。 如下图所示:  我们可以看到,文件名被成功截断,php脚本上传成功。  ### 受影响的php版本 5.4.38~5.6.6,同时由于php 5.2版本本身就受到00截断漏洞的影响,所以也在受影响的行列之中。 ### 参考链接: http://bobao.360.cn/news/detail/1383.html |
