Cisco mentioned the difficulty needed to do with lacking authentication for a important operate. 

    “The best solution to mitigate makes an attempt to use this vulnerability is to forestall entry to the configuration port (TCP/58727 by default) when not actively configuring the OAS Platform,” Cisco Talos mentioned.

    The REST API-related vulnerability (CVE-2022-26833) that Cisco found and reported to OAS additionally stems from improper authentication. The flaw exists in OAS Platform V16.00.0121 and offers unauthenticated attackers a means to make use of the REST API to make malicious modifications to the platform. Attackers can set off the flaw by sending a collection of specifically crafted HTTP requests to the software program.
