Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an incomplete fox for #VU72427 (CVE-2023-24998). If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed. A remote attacker can initiate a series of uploads and perform a denial of service (DoS) attack.
