3) Resource exhaustion

EUVDB-ID: #VU77573

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-34462

CWE-ID: CWE-400 - 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 application does not properly control consumption of internal resources if no idle timeout handler was configured. A remote attacker can send a client hello packet, which leads the server to buffer up to 16MB of data per connection and results in a denial of service condition.

Mitigation

Install update from vendor's website.

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

5) Resource management error

EUVDB-ID: #VU76427

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-20883

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

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

The vulnerability exists due to improper management of internal resources within the application. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

Specifically, an application is vulnerable if all of the conditions are true:

  • The application has Spring MVC auto-configuration enabled. This is the case by default if Spring MVC is on the classpath.
  • The application makes use of Spring Boot's welcome page support, either static or templated.
  • Your application is deployed behind a proxy which caches 404 responses.

Mitigation

Install update from vendor's website.
