Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Inconsistent interpretation of HTTP requests
EUVDB-ID: #VU68859
Risk: Medium
CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-42252
CWE-ID:
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers via an invalid
Content-Length header.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks but requires Tomcat to be configured to ignore invalid HTTP headers via setting
rejectIllegalHeader to false (not the default configuration).
Update the affected packages.
www-servers/tomcat to version: 10.1.8
Gentoo Linux: All versions
www-servers/tomcat: before 10.1.8

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Code Injection
EUVDB-ID: #VU70666
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-45143
CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to manipulate server output.
The vulnerability exists due to improper input validation within the JsonErrorReportValve when handling type, message or description values. A remote attacker can send a specially crafted request and manipulate or invalidate JSON output.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.

3) 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
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to Apache Commons FileUpload does not limit the number of request parts. A remote attacker can initiate a series of uploads and perform a denial of service (DoS) attack.
Update the affected packages.
www-servers/tomcat to version: 10.1.8
Gentoo Linux: All versions

4) 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. MitigationUpdate the affected packages.
