Description
Inefficient algorithmic complexity in ASP.NET Core allows an unauthorized attacker to deny service over a network.
Statement
This vulnerability is rated as Moderate severity because successful exploitation requires specific request transmission timing, causing excessive CPU utilization without compromising data integrity or system confidentiality. ASP.NET Core applications running on Red Hat platforms that accept and process untrusted form data are susceptible to service degradation. However, the issue does not allow privilege escalation or arbitrary code execution, restricting the impact exclusively to application availability.
