Description

## Summary IBM PowerVM Novalink is vulnerable because Dojo cloud allow a remote attacker to execute arbitrary code on the system due to WebSphere Liberty, caused by a prototype pollution in the setObject function. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system. (CVE-2021-23450) ## Vulnerability Details ** CVEID: **[CVE-2021-23450](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23450>) ** DESCRIPTION: **Dojo could allow a remote attacker to execute arbitrary code on the system, caused by a prototype pollution in the setObject function. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
