CVE-2016-6602: Zohocorp Webnms Framework: Use of a Broken or Risky Cryptographic Algorithm

CVE-2016-6602 is rated critical with a CVSS v3.0 base score of 9.8 and affects Zohocorp Webnms Framework. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

ZOHO WebNMS Framework 5.2 and 5.2 SP1 use a weak obfuscation algorithm to store passwords, which allows context-dependent attackers to obtain cleartext passwords by leveraging access to WEB-INF/conf/securitydbData.xml. NOTE: this issue can be combined with CVE-2016-6601 for a remote exploit.
