CVE-2025-68161
Description
A flaw was found in Apache Log4j Core. The Socket Appender component fails to perform proper TLS (Transport Layer Security) hostname verification of peer certificates. This vulnerability allows a man-in-the-middle (MITM) attacker to intercept or redirect log traffic, potentially leading to information disclosure. Exploitation requires the attacker to intercept network traffic and present a server certificate issued by a trusted certification authority.
Statement
This vulnerability is rated Moderate for Red Hat products utilizing Apache Log4j Core versions 2.0-beta9 through 2.25.2 with the Socket Appender configured for TLS. The flaw allows a man-in-the-middle attacker to intercept or redirect log traffic due to missing TLS hostname verification, provided the attacker can intercept network traffic and present a trusted certificate.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
