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

Medium Nessus Plugin ID 127255

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 7.4

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 - [email protected]: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.
