Summary

The msLoadQuery function in mapserv in MapServer 4.x before 4.10.4 and 5.x before 5.2.2 allows remote attackers to determine the existence of arbitrary files via a full pathname in the queryfile parameter, which triggers different error messages depending on whether this pathname exists.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

    descriptionSeveral vulnerabilities have been discovered in mapserver, a CGI-based web framework to publish spatial data and interactive mapping applications. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-0843 Missing input validation on a user-supplied map queryfile name can be used by an attacker to check for the existence of a specific file by using the queryfile GET parameter and checking for differences in error messages. - CVE-2009-0842 A lack of file type verification when parsing a map file can lead to partial disclosure of content from arbitrary files through parser error messages. - CVE-2009-0841 Due to missing input validation when saving map files under certain conditions it is possible to perform directory traversal attacks and to create arbitrary files.

"Several vulnerabilities have been discovered in mapserver, a CGI-based
web framework to publish spatial data and interactive mapping
applications. The Common Vulnerabilities and Exposures project
identifies the following problems :

  - CVE-2009-0843
    Missing input validation on a user-supplied map
    queryfile name can be used by an attacker to check for
    the existence of a specific file by using the queryfile
    GET parameter and checking for differences in error
    messages.

  - CVE-2009-0842
    A lack of file type verification when parsing a map file
    can lead to partial disclosure of content from arbitrary
    files through parser error messages.

  - CVE-2009-0841
    Due to missing input validation when saving map files
    under certain conditions it is possible to perform
    directory traversal attacks and to create arbitrary
    files. NOTE: Unless the attacker is able to create
    directories in the image path or there is already a
    readable directory this doesn't affect installations on
    Linux as the fopen() syscall will fail in case a sub
    path is not readable.

  - CVE-2009-0839
    It was discovered that mapserver is vulnerable to a
    stack-based buffer overflow when processing certain GET
    parameters. An attacker can use this to execute
    arbitrary code on the server via crafted id parameters.

  - CVE-2009-0840
    An integer overflow leading to a heap-based buffer
    overflow when processing the Content-Length header of an
    HTTP request can be used by an attacker to execute
    arbitrary code via crafted POST requests containing
    negative Content-Length values.

  - CVE-2009-2281
    An integer overflow when processing HTTP requests can
    lead to a heap-based buffer overflow. An attacker can
    use this to execute arbitrary code either via crafted
    Content-Length values or large HTTP request. This is
    partly because of an incomplete fix for CVE-2009-0840."

descriptionBUGTRAQ ID: 34306 CVE(CAN) ID: CVE-2009-0839,CVE-2009-0840,CVE-2009-0841,CVE-2009-0843,CVE-2009-0842,CVE-2009-1176,CVE-2009-1177 MapServer是用于创建交互式地图应用的多平台程序。 MapServer中存在多个安全漏洞，可能允许远程攻击者泄露敏感信息、绕过安全限制、导致拒绝服务或入侵有漏洞的系统。 1) 如果远程攻击者向服务器上传了恶意地图文件或通过id参数传送了包含有超过128字节字符串的特制请求的话，就可以在mapserv CGI程序中触发栈溢出，导致执行任意代码。以下是mapserv.c中有漏洞的代码段： 406: strncpy(mapserv-&gt;Id, mapserv-&gt;request-&gt;ParamValues[i], IDSIZE); 1112: int main(int argc, char *argv[]) { 1114: char buffer[1024], *value=NULL; 1783: sprintf(buffer, \&quot;%s%s%s%s\&quot;, mapserv-&gt;map-&gt;web.imagepath, \\ mapserv-&gt;map-&gt;name, mapserv-&gt;Id, MS_QUERY_EXTENSION); 1826: } 2) mapserv CGI程序在处理Content-Length头时存在索引错误，远程攻击者可以通过提交特制的POST请求触发堆溢出，导致越界数组访问。成功攻击要求web服务器没有过滤Content-Length头。 3) 由于没有过滤对mapserv CGI程序所传送的id参数，远程攻击者可以通过目录遍历攻击向任意位置写入文件。以下是有漏洞部分的代码段： [mapserv.c] 1783: sprintf(buffer, \&quot;%s%s%s%s\&quot;, mapserv-&gt;map-&gt;web.imagepath, \\ mapserv-&gt;map-&gt;name, mapserv-&gt;Id, MS_QUERY_EXTENSION); 1784: if((status = msSaveQuery(mapserv-&gt;map, buffer)) != MS_SUCCESS) \\ return status; [mapquery.c] 89: stream = fopen(filename, \&quot;wb\&quot;); 90: if(!stream) { 91: [...] 92: return(MS_FAILURE); 93: } 4) 如果攻击者在.map文件中通过map参数指定了完整路径，则mapserv CGI程序在处理该文件时就会泄露文件中的敏感信息。 5) mapserv CGI程序对系统中是否存在的文件会返回不同的错误消息，远程攻击者可以利用queryfile请求参数判断是否存在特定的文件。 6) 特制的地图文件可以在maptemplate.c的msGenerateImages()函数中触发栈溢出。 University of Minnesota MapServer 5.2.1 University of Minnesota MapServer 4.10.3 University of Minnesota ----------------------- 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载： <a href=http://download.osgeo.org/mapserver/mapserver-4.10.4.tar.gz target=_blank rel=external nofollow>http://download.osgeo.org/mapserver/mapserver-4.10.4.tar.gz</a> <a href=http://download.osgeo.org/mapserver/mapserver-5.2.2.tar.gz target=_blank rel=external nofollow>http://download.osgeo.org/mapserver/mapserver-5.2.2.tar.gz</a>
