CGI web servers assign Proxy header values from client requests to internal HTTP_PROXY environment variables

Vulnerability Note VU#797896

Original Release Date: 2016-07-18 | Last Revised: 2016-07-19

Overview

Web servers running in a CGI or CGI-like context may assign client request Proxy header values to internal HTTP_PROXY environment variables. This vulnerability can be leveraged to conduct man-in-the-middle (MITM) attacks on internal subrequests or to direct the server to initiate connections to arbitrary hosts.

Description

CWE-807: Reliance on Untrusted Inputs in a Security Decision, CWE-454: External Initialization of Trusted Variables or Data Stores

Web servers running in a CGI or CGI-like context may assign client request Proxy header values to internal HTTP_PROXY environment variables. The vulnerable behavior is the result of a naming convention for meta-variables, defined in RFC 3876, which leads to a name collision: "The HTTP header field name is converted to upper case, has all occurrences of "-" replaced with "_" and has "HTTP_" prepended to give the meta-variable name."

According to the researchers, a web server is vulnerable if:

    1. A web server, programming language or framework (and in some limited situations the application itself) sets the environmental variable HTTP_PROXY from the user supplied Proxy header in the web request, or sets a similarly used variable (essentially when the request header turns from harmless data into a potentially harmful environmental variable).
    2. A web application makes use of HTTP_PROXY or similar variable unsafely (e.g. fails to check the request type) resulting in an attacker controlled proxy being used (essentially when HTTP_PROXY is actually used unsafely).

    By sending a specially crafted request to a vulnerable server, a remote, unauthenticated attacker may be able to conduct MITM attacks on internal server subrequests or direct the server to initiate connections to arbitrary hosts. For more information, refer to httpoxy.org.

    Impact

    A remote, unauthenticated attacker may be able to conduct MITM attacks on internal server subrequests or direct the server to initiate connections to arbitrary hosts.

    Solution

    Apply an update

    Where applicable, affected products and components should be updated to address this vulnerability. Check with vendors for information about patching.

    Where patches are unavailable or updating is not an option, consider the following workarounds.

    Filter Proxy request headers

    The researchers and community have identified several filtering strategies that are product-dependent:

    Apache/CGI

    In this configuration, any language may be vulnerable (the HTTP_PROXY env var is "real"). If you are using mod_headers , you can unset the "Proxy" header with this directive:

          RequestHeader unset Proxy

    If you are using mod_security, you can use a rule like (vary the action to taste):
          SecRuleEngine On
          SecRule &REQUEST_HEADERS:Proxy "@gt 0"
          "id:1000005,log,deny,msg:'httpoxy denied'"

    Refer to Apache's response for more information.

    HAProxy

          httprequest delheader Proxy

    lighttpd <= 1.4.40 (reject requests containing "Proxy" header)

    Create "/path/to/deny-proxy.lua", read-only to lighttpd, with content:
          if (lighty.request["Proxy"] == nil) then return 0 else return 403 end
    Modify lighttpd.conf to load mod_magnet and run lua code
          server.modules += ( "mod_magnet" )
         magnet.attract-raw-url-to = ( "/path/to/deny-proxy.lua" )

    lighttpd2 (development) (strip "Proxy" header from request)

    Add to lighttpd.conf:
          req_header.remove "Proxy";

    Nginx/FastCGI

    Use this to block the Proxy header from being passed on to PHPFPM, PHPPM, etc.
          fastcgi_param HTTP_PROXY ;

    Nginx with proxy_pass

    The following setting should work for people who are using "proxy_pass" with nginx:

          proxy_set_header Proxy ;


    Microsoft has provided the following guidance for IIS servers utilizing affected third-party frameworks:

    Microsoft IIS Mitigation steps:

    Update apphost.config with the following rule:

      <system.webServer>


         <rewrite>

              <rules>

                  <rule name=3D"Erase HTTP_PROXY" patternSyntax=3D"Wildcard">

                      <match url=3D"*.*" />

                      <serverVariables>

                          <set name=3D"HTTP_PROXY" value=3D />

                      </serverVariables>

                      <action type=3D"None" />

    Status

      Affected

    Vendor Statement

    The Apache Software Foundation has discovered no examples of condition 2 described in the [redacted] report, and has determined there is no "vulnerability" per se in ASF software, which conform to both RFC822 (circa 1982) and CGI/1.1 defacto standard (circa 1995, superseded by CGI/1.1 IANA spec RFC 3875).

    Several ASF projects participate in HTTP requests in the manners described under condition 1. The list of projects that will offer one or more mitigations include but are not limited to;

    Apache HTTP Server (httpd) (Tracked as CVE-2016-5387)
    Apache Tomcat Server (Tracked as CVE-2016-5388)
    Apache Traffic Server (ATS) (Tracking is not applicable)

    Projects and subprojects impacted by the Apache HTTP Server mitigations will include mod_fcgid (Apache HTTP Project) and mod_perl (Apache Perl Project), as well as external projects such as mod_wsgi, all hopefully under CVE-2016-5387.

    Note specifically that any CVE related to mod_fcgi[d] must be ignored, as it duplicates CVE-2016-5387. We have not reached a conclusion on separate tracking that might be unique to mod_perl itself (thus far, it also appears to duplicate -5387.)
