CVE-2023-24998
HighCVSS 7.5Exploitation Probability (EPSS)
Very high risk99th percentile - higher than 99% of all known CVEs
Summary
Apache Commons FileUpload before 1.5 does not limit the number of request parts to be processed resulting in the possibility of an attacker triggering a DoS with a malicious upload or series of uploads. Note that, like all of the file upload limits, the new configuration option (FileUploadBase#setFileCountMax) is not enabled by default and must be explicitly configured.
Risk Assessment
An attacker could overload the server by sending many parts in a request, potentially leading to resource exhaustion and service unavailability. This could disrupt applications using Commons FileUpload.
Recommendation
Upgrade Apache Commons FileUpload to version 1.5 or later. Enable and configure the FileUploadBase#setFileCountMax option to limit the number of request parts.
