Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Code Injection

EUVDB-ID: #VU103289

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-12798

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

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper input validation in JaninoEventEvaluator extension when handling environment variables. A local user can inject specially crafted data into environment variables and execute arbitrary code with elevated privileges.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

openEuler: 20.03 LTS SP4 - 24.03 LTS

logback-help: before 1.2.8-4

logback-examples: before 1.2.8-4

logback-access: before 1.2.8-4

logback: before 1.2.8-4

2) XML External Entity injection

EUVDB-ID: #VU103290

Risk: Medium

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

CVE-ID: CVE-2024-12801

CWE-ID: CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient validation of user-supplied XML input in SaxEventRecorder. A remote attacker can pass a specially crafted configuration XML file to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.

Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.

Mitigation

Install updates from vendor's repository.
