[R1] Tenable.sc 6.0.0 Fixes Multiple Vulnerabilities
Critical
Synopsis
Tenable.sc leverages third-party software to help provide underlying
functionality. Several of the third-party components (moment.js, libcurl) were
found to contain vulnerabilities, and updated versions have been made available
by the providers. Additionally, four separate vulnerabilities were discovered,
reported and fixed.
1. CVE-2023-24493 - A formula injection vulnerability exists in Tenable.sc due
to improper validation of user-supplied input before returning it to users. An
authenticated attacker could leverage the reporting system to export reports
containing formulas, which would then require a victim to approve and execute
on a host.
2. CVE-2023-24494 - A stored cross-site scripting (XSS) vulnerability exists in
Tenable.sc due to improper validation of user-supplied input before returning
it to users. An authenticated, remote attacker can exploit this by convincing a
user to click a specially crafted URL, to execute arbitrary script code in a
user's browser session.
3. CVE-2023-24495 - A Server Side Request Forgery (SSRF) vulnerability exists
in Tenable.sc due to improper validation of session & user-accessible input
data. A privileged, authenticated remote attacker could interact with external
and internal services covertly.
4. CVE-2023-0476 - A LDAP injection vulnerability exists in Tenable.sc due to
improper validation of user-supplied input before returning it to users. An
authenticated attacker could generate data in Active Directory using the
application account through blind LDAP injection.
Out of caution and in line with best practice, Tenable has opted to upgrade
these components and fix the additional reported vulnerabilities to address the
potential impact of the issues. Tenable.sc 6.0.0 fixes the reported
vulnerabilities, updates moment.js to version 2.29.4 and libcurl to version
7.86.0.
Solution
Tenable has released Tenable.sc 6.0.0 to address these issues. The installation
files can be obtained from the Tenable Downloads Portal: https://
