NewStart CGSL CORE 5.04 / MAIN 5.04 : python Multiple Vulnerabilities (NS-SA-2019-0061)

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has python packages installed that are affected by multiple vulnerabilities:

- A flaw was found in the way catastrophic backtracking was implemented in python's pop3lib's apop() method. An attacker could use this flaw to cause denial of service.
(CVE-2018-1060)

- A flaw was found in the way catastrophic backtracking was implemented in python's difflib.IS_LINE_JUNK method.
An attacker could use this flaw to cause denial of service. (CVE-2018-1061)

- It was discovered that python's functions urllib.parse.urlsplit and urllib.parse.urlparse do not properly handle URLs encoded with Punycode/Internationalizing Domain Names in Applications (IDNA), which may result in a wrong domain name (specifically the netloc component of URL - user@domain:port) being returned by those functions.
When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed.
The result of an attack may vary based on the application. (CVE-2019-9636)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL python packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
