On May 20, 2020, Cisco Systems repaired a crucial remote code execution vulnerability present in the  Unified Contact Center Express solution. Along with this, the tech space witnessed a frenzy of patches and bug releases announced by Adobe, Microsoft, and Google.

More about the bug

The bug that was fixed early this week was discovered in Unified CCX’s Java Remote Management Interface. The primary reason for the crucial Cisco flaw (with a CVSS base score of 9.8) is the insecure de-serialization of the content supplied by users.

Additionally, Cisco was also involved in repairing four other bugs like denial of service (DOS) vulnerability in the DHCP server of the Prime Network Registrar, which were of high importance, and three other bugs that were categorized as of medium importance.


In an advisory by Cisco, the company mentions that the dubious threat actors could misuse it with malevolent serialized Java objects with an aim to play the arbitrary code as the root user.
