Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Inconsistent interpretation of HTTP requests

EUVDB-ID: #VU68859

Risk: Medium

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-42252

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

Exploit availability: No

Description

The 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).

Mitigation

Update tomcat9 package to version 9.0.43-2~deb11u6.

Vulnerable software versions

Debian Linux: All versions

tomcat9 (Debian package): before 9.0.43-2~deb11u6

2) Code Injection

EUVDB-ID: #VU70666

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-45143

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

The 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.

Mitigation

3) Sensitive cookie in HTTPS session without Secure attribute

EUVDB-ID: #VU73957

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-28708

CWE-ID: CWE-614 - Sensitive Cookie in HTTPS Session Without 'Secure' Attribute

Exploit availability: No
