CVE-2013-4521 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. RichFaces implementation in Nuxeo Platform 5.6.0 before HF27 and 5.8.0 before HF-01 does not restrict the classes for which deserialization methods can be called, which allows remote attackers to execute arbitrary code via crafted serialized data. NOTE: this vulnerability may overlap CVE-2013-2165.. EPSS estimates a 4.14% chance of exploitation in the next 30 days.
