CVE-2020-15589 and CVE-2020-24397 are grouped together with this.

I want to clarify that these are client-side vulnerabilities in ManageEngine Desktop Central. Exploiting them will certainly require MITM or other control of the network.

Details and a PoC are available, so patch this immediately. Desktop Central is UEM software, and while this is a set of client-side vulns, you don’t want attackers taking advantage of such critical software.
