CVE-2016-6602
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.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 55.7%, higher than 99% of all known CVEs. Patch or mitigate before the next change window.
