Because it doesn't require any prior access credentials or social engineering techniques, this poses a serious risk and is therefore a desirable target for malevolent actors looking to compromise enterprise remote access infrastructure.

Prior to applying the security patch, customers using Privileged Remote Access versions older than 22.1 or Remote Support versions older than 21.3 must upgrade to a supported version.
