Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
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.

EUVDB-ID: #VU81865
Risk: High
CVSSv3.1: 7.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2023-38545
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the SOCKS5 proxy handshake. A remote attacker can trick the victim to visit a malicious website, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that SOCKS5 proxy is used and that SOCKS5 handshake is slow (e.g. under heavy load or DoS attack).

EUVDB-ID: #VU81863
Risk: Low
CVSSv3.1: 2.3 [CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-38546
CWE-ID:
CWE-73 - External Control of File Name or Path
Exploit availability: No
DescriptionThe vulnerability allows an attacker to inject arbitrary cookies into request.
The vulnerability exists due to the way cookies are handled by libcurl. If a transfer has cookies enabled when the handle is duplicated, the
cookie-enable state is also cloned - but without cloning the actual
cookies. If the source handle did not read any cookies from a specific
file on disk, the cloned version of the handle would instead store the
file name as none
(using the four ASCII letters, no quotes).
none
- if such a file exists and is readable in the current directory of the program using libcurl.

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.

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.

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.
