Tenable SecurityCenter OpenSSL < 1.1.1l Multiple Vulnerabilities (TNS-2021-16)

critical Nessus Plugin ID 153589
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

An application installed on the remote host is affected by multiple vulnerabilities.

Description

According to its self-reported version, the Tenable SecurityCenter application installed on the remote host is missing the security patch SC-202109.1, therefore affected by multiple vulnerabilities as referenced in the 1.1.1l advisory:

- A heap-based buffer overflow condition exists due to the implementation of the SM2 decryption. An unauthenticated, remote attacker can exploit this, via specially crafted request, to cause a denial of service condition or the execution of arbitrary code. (CVE-2021-3711)

- An out-of-bounds read error exists in due to improper handling of ASN.1 strings. An unauthenticated, remote attacker can exploit this, via a specially crafted ASN1_STRING structure, to cause a denial of service condition or disclosure of sensitive information. (CVE-2021-3712)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported patching information.

Solution

Apply the security patch referenced in the vendor advisory.
