1) Resource exhaustion

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2019-11048

CWE-ID: CWE-400 - Uncontrolled Resource Consumption ('Resource Exhaustion')

Exploit availability: No

Description

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

The vulnerability exists due to the way PHP handles long filenames or field names during file upload. A remote attacker can supply an overly long filename to the application that will lead PHP engine to try to allocate oversized memory storage, hit the memory limit and stop processing the request, without cleaning up temporary files created by upload request. This will lead to accumulation of uncleaned temporary files exhausting the disk space on the target server.

Mitigation

Update the affected packages.
