In Eclipse Jersey versions 2.45, 3.0.16, and 3.1.9, a race condition can cause ignoring of critical SSL configurations, such as mutual authentication, custom key/trust stores, and other security settings. This issue may result in SSLHandshakeException under normal circumstances, but under certain conditions, it could lead to unauthorized trust in insecure servers.
The severity level for this vulnerability is classified as critical, with a CVSS score of 9.4. This high score indicates that the potential impact of the vulnerability is severe, particularly concerning confidentiality and integrity.
Risk to organizations includes the possibility of unauthorized access to sensitive information due to misconfigured SSL settings. Attackers may leverage this vulnerability to exploit trust relationships and gain access to system resources.
Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability. Without prompt remediation, systems remain susceptible to potential exploitation.
Vulnerability Details
The official description states that a race condition in the mentioned versions of Eclipse Jersey can lead to critical SSL configuration settings being ignored. The affected components are primarily the Jersey libraries used in web applications.
The vulnerability is classified under CWE-362, indicating a race condition issue. The CVSS 4.0 score reflects a high attack complexity that requires a certain set of conditions to be met for exploitation.
The vulnerability was published on November 18, 2025, and organizations are encouraged to check their implementations for the specified versions of Jersey.
Technical Analysis
The root cause of the vulnerability lies in a race condition that allows SSL configurations to be bypassed. The attack vector is network-based, and the required privileges are none, meaning that the vulnerability can be exploited by any user without authentication.
This vulnerability poses a high confidentiality and integrity impact, as attackers may gain unauthorized trust in insecure servers. User interaction is not required for exploitation, which further increases the risk.
Risk & Impact Analysis
The race condition vulnerability in Eclipse Jersey presents a real-world risk for organizations utilizing these libraries. The potential for unauthorized access, coupled with the critical severity rating, underscores the need for immediate remediation.
The blast radius of this vulnerability is significant, as it affects multiple versions of Jersey. Organizations that fail to patch will expose themselves to various attack vectors, leading to potential data breaches.
Given the critical nature of this vulnerability and its potential impact, organizations should address this issue in their priority patch cycle. The urgency is reflected in the high CVSS score and the exploitability rating.
