Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Inconsistent interpretation of HTTP requests
EUVDB-ID: #VU81799
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-2023-45648
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 when parsing HTTP trailer headers. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
MitigationInstall update from vendor's website.
Vulnerable software versionsIBM Integration Bus: 10.1 - 10.1.0.2

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) Exposed dangerous method or function
EUVDB-ID: #VU81803
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-2023-42794
CWE-ID:
CWE-749 - Exposed Dangerous Method or Function
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to Tomcat's internal fork of a Commons FileUpload included an unreleased, in progress refactoring that exposed a potential denial of service on Windows. A remote attacker can perform a denial of service attack by uploading multiple files to the server that are not removed.

3) Resource exhaustion
EUVDB-ID: #VU81728
Risk: High
CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:H/RL:O/RC:C]
CVE-ID: CVE-2023-44487
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".
Note, the vulnerability is being actively exploited in the wild.

4) 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.
