CVE-ID: CVE-2024-4109

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to incorrect handling of HTTP/2 requests when reusing connections, which results in parts of data from previous connection to be included into new responses. A remote attacker can send an HTTP/2 request to the server and gain access to potentially sensitive information.

Mitigation

Install updates from vendor's repository.

2) Resource management error

EUVDB-ID: #VU48779

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-17527

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to improper management of internal resources within the application when processing HTTP/2 requests in Apache Tomcat. The web server can re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. As a result a remote attacker can obtain sensitive information from another HTTP request.

Mitigation

Install updates from vendor's repository.
