Liferay Portal Insecure Deserialization (CST-7213)

high Nessus Plugin ID 151011


New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


An application running on a remote web server host is affected by an insecure deserialization vulnerability


Liferay Portal before 7.3.0, 7.1 before fix pack 17, and 7.2 before fix pack 5, allows man-in-the-middle attackers to execute arbitrary code via crafted serialized payloads, because of insecure deserialization.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Refer to the vendor advisory.
