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.

Synopsis

The remote web server has multiple SSL-related vulnerabilities.

Description

According to its banner, the remote web server is running a version of OpenSSL older than 0.9.8n. Such versions have the following vulnerabilities :

- Kerberos-enabled versions of OpenSSL do not check the return value when Kerberos configuration files cannot be opened, leading to a crash. (CVE-2010-0433)

- Rejecting a SSL/TLS record with an incorrect version number can lead to a crash. This only affects version 0.9.8m if a 'short' is 16 bits. Otherwise, it affects all versions back to and including 0.9.8f. (CVE-2010-0740)

Solution

Upgrade to OpenSSL 0.9.8n or later.
