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

critical Nessus Plugin ID 153589

Language:

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.
