Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Resource management error
EUVDB-ID: #VU100587
Risk: Medium
CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Green]
CVE-ID: CVE-2024-52317
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to improper management of internal resources when handling HTTP/2 responses, which causes request and/or response mix-up between users. A remote non-authenticated attacker can send a series of HTTP/2 requests and gain access to sensitive information.
Install updates from vendor's website.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) Improper Authentication
EUVDB-ID: #VU100588
Risk: Low
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2024-52316
CWE-ID:
CWE-287 - Improper Authentication
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error when processing authentication requests. If Tomcat was configured to use a custom Jakarta Authentication (formerly JASPIC) ServerAuthContext component which may throw an exception during the authentication process without explicitly setting an HTTP status to indicate failure, the authentication may not have failed, allowing the user to bypass the authentication process.
MitigationInstall updates from vendor's website.
