1) Improper Handling of Exceptional Conditions

EUVDB-ID: #VU55422

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-30639

CWE-ID: CWE-755 - Improper Handling of Exceptional Conditions

Exploit availability: No

Description

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

The vulnerability exists due to improper error management within the application when handling unexpected connection termination. A remote attacker can drop connection with the Apache Tomcat server, which triggers a non-blocking I/O error and causes all requests, handled by that request object, to fail. As a result, a remote attacker can initiate and drop connections to the server and perform a denial of service attack.

Mitigation

Install update from vendor's website.
