Description Dhananjay Arunesh 2019-04-24 10:23:46 UTC
A buffer over-read in Util_urlDecode in util.c in Tildeslash Monit before 5.25.3 allows a remote authenticated attacker to retrieve the contents of adjacent memory via manipulation of GET or POST parameters. The attacker can also cause a denial of service (application outage).
