Medium Nessus Plugin ID 127268

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: 4.4

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

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

- It was found that GnuTLS's implementation of HMAC- SHA-256 was vulnerable to Lucky Thirteen-style attack. A remote attacker could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets. (CVE-2018-10844)

- It was found that GnuTLS's implementation of HMAC- SHA-384 was vulnerable to a Lucky Thirteen-style attack.
A remote attacker could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets. (CVE-2018-10845)

- A cache-based side channel attack was found in the way GnuTLS implements CBC-mode cipher suites. An attacker could use a combination of Just in Time Prime+probe and Lucky-13 attacks to recover plain text in a cross-VM attack scenario. (CVE-2018-10846)

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 gnutls packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
