AI-suggested

If you cannot patch yet, restrict access to users with 'All' permissions and carefully validate or limit file uploads to the WAF rule functionality to mitigate risk.

Description

An OS command injection vulnerability exists in the UI of Progress ADC LoadMaster products. An authenticated attacker with 'All' permissions can exploit unsanitized input in a custom WAF rule file upload to execute arbitrary commands on the appliance. This vulnerability allows full compromise of confidentiality, integrity, and availability of the device.
