Vulnerability identifier: #VU117682
Vulnerability risk: Medium
CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID:
CWE-ID:
CWE-400
Exploitation vector: Network
Exploit availability: No
Vulnerable software:
Apache Tomcat
Server applications /
Web servers
Vendor: Apache Foundation
Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when handling errors while processing multipart upload. Depending on JVM settings, application memory usage and application load, it is possible that space for the temporary copies of uploaded parts would be filled faster than GC cleared it, leading to a DoS.
Mitigation
Install updates from vendor's website.
