Debian Security Advisory DSA 3062-1 (wget - security update)
Published: 2014-10-31 23:00:00
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:M/Au:N/C:C/I:C/A:C
Affected Versions:
wget on Debian Linux
Recommendations:
For the stable distribution (wheezy), this problem has been fixed in
version 1.13.4-3+deb7u2.
For the unstable distribution (sid), this problem has been fixed in
version 1.16-1.
We recommend that you upgrade your wget Linux Distribution Packages.
Summary:
HD Moore of Rapid7 discovered a symlink attack in Wget, a command-line
utility to retrieve files via HTTP, HTTPS, and FTP. The vulnerability
allows to create arbitrary files on the user's system when Wget runs in
recursive mode against a malicious FTP server. Arbitrary file creation
may override content of user's files or permit remote code execution with
the user privilege.
This update changes the default setting in Wget such that it no longer
creates local symbolic links, but rather traverses them and retrieves the
pointed-to file in such a retrieval.
Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.
Detection Type:
Linux Distribution Package
Solution Type:
Vendor Patch

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".
