Attack Vector: Network

Confidentiality: None
Integrity: High
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 8 Nov 2023
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

European organizations should implement the following specific mitigations: 1) Apply official patches from Red Hat as soon as they become available to address CVE-2023-4061. 2) Restrict access to the HAL management interface strictly to trusted administrators via network segmentation, VPNs, or firewall rules. 3) Enforce strong authentication and authorization policies for management users, including multi-factor authentication where possible. 4) Regularly audit management user accounts and their privileges to minimize the number of users with management access. 5) Monitor logs and network traffic for unusual access patterns to the HAL interface or resolve-expression usage. 6) Consider disabling or limiting resolve-expression functionality if not required for operations. 7) Conduct security awareness training for administrators about the risks of exposing management interfaces. 8) Employ runtime application self-protection (RASP) or web application firewalls (WAF) that can detect and block suspicious management interface activity.

Description

A flaw was found in wildfly-core. A management user could use the resolve-expression in the HAL Interface to read possible sensitive information from the Wildfly system. This issue could allow a malicious user to access the system and obtain possible sensitive information from the system.

Impact

For European organizations, especially those in sectors like finance, government, telecommunications, and critical infrastructure that rely on Red Hat JBoss EAP 7, this vulnerability could lead to unauthorized disclosure of sensitive configuration or operational data. Such exposure might facilitate lateral movement, privilege escalation, or data breaches. Since exploitation requires management privileges, the risk is heightened in environments with weak access controls or where insider threats exist. The confidentiality breach could undermine compliance with GDPR and other data protection regulations, leading to legal and reputational consequences. The vulnerability does not directly impact system availability or integrity but could be a stepping stone for more severe attacks. Organizations with extensive use of JBoss EAP 7 in multi-tenant or cloud environments may face increased risk if management interfaces are exposed or poorly secured.
