Liferay Portal < REDoS

high Nessus Plugin ID 176448


An application running on a remote web server host is affected by a denial of service vulnerability


Pattern Redirects in Liferay Portal and Liferay DXP allows regular expressions that are vulnerable to ReDoS attacks to be used as patterns, which allows remote attackers to consume an excessive amount of server resources via crafted request URLs.

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


Upgrade to Liferay Portal or later.
