CentOS Update for python-twisted-web CESA-2016:1978 centos7
Published: 2016-10-05 10:13:19
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C
Detection Type:
Linux Distribution Package
Summary:
Check the version of python-twisted-web
Detection Method:
Checks if a vulnerable version is present on the target host.
Technical Details:
Twisted is an event-based framework for
internet applications. Twisted Web is a complete web server, aimed at hosting
web applications using Twisted and Python, but fully able to serve static pages
too.
Security Fix(es):
* It was discovered that python-twisted-web used the value of the Proxy
header from HTTP requests to initialize the HTTP_PROXY environment variable
for CGI scripts, which in turn was incorrectly used by certain HTTP client
implementations to configure the proxy for outgoing HTTP requests. A remote
attacker could possibly use this flaw to redirect HTTP requests performed
by a CGI script to an attacker-controlled proxy via a malicious HTTP
request. (CVE-2016-1000111)
Note: After this update, python-twisted-web will no longer pass the value
of the Proxy request header to scripts via the HTTP_PROXY environment
variable.
Red Hat would like to thank Scott Geary (VendHQ) for reporting this issue.
Affected Versions:
python-twisted-web on CentOS 7
Recommendations:
Please Install the Updated Packages.
Solution Type:

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
