This security bulletin contains information about 3 vulnerabilities.
1) Allocation of Resources Without Limits or Throttling
EUVDB-ID: #VU72427
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-24998
CWE-ID:
CWE-770 - Allocation of Resources Without Limits or Throttling

2) Allocation of Resources Without Limits or Throttling
EUVDB-ID: #VU76417
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-28709
CWE-ID:
CWE-770 - Allocation of Resources Without Limits or Throttling
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an incomplete fox for #VU72427 (CVE-2023-24998). If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed. A remote attacker can initiate a series of uploads and perform a denial of service (DoS) attack. MitigationInstall updates from vendor's repository.

3) Resource management error
EUVDB-ID: #VU81800
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-42795
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe 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 recycling various internal objects. A remote attacker can force Tomcat to skip some parts of the recycling process leading to information leaking from the current request/response to the next.
