Description

This security bulletin contains information about 1 security vulnerability.


1) Code Injection (CVE-ID: CVE-2021-31805)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation caused by incomplete fix for #VU48815 (CVE-220-17530). Still some of the tag's attributes could perform a double evaluation if a developer applied forced OGNL evaluation by using the %{...} syntax. A remote attacker can send a specially crafted request and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
