[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.
