Attack Vector: Network
Attack Complexity: Low

User Interaction: None
Scope: Unchanged
Confidentiality: High
Integrity: None
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Dec 2025
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.

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 2026-10-25.

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 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.

AI-suggested

To mitigate CVE-2025-42904, European organizations should: 1) Immediately review and restrict access controls to SAP Application Server ABAP environments, ensuring that only authorized personnel have access to sensitive ABAP lists. 2) Conduct audits of user privileges and remove or limit accounts with unnecessary access to sensitive data displays. 3) Implement monitoring and alerting for unusual access patterns or attempts to view sensitive ABAP lists. 4) Apply SAP security notes and patches as soon as they become available, maintaining close communication with SAP support channels for updates. 5) Where possible, configure SAP systems to enforce masking of password fields or sensitive data in ABAP lists, potentially through custom development or configuration changes. 6) Educate users and administrators about the risks of exposing sensitive information and enforce strong authentication and session management practices to reduce the risk of credential compromise. 7) Consider network segmentation to isolate SAP systems and limit exposure to potential attackers. 8) Perform regular security assessments and penetration testing focused on SAP environments to detect similar issues proactively.

Description

Due to an Information Disclosure vulnerability in Application Server ABAP, an authenticated attacker could read unmasked values displayed in ABAP Lists. Successful exploitation could lead to unauthorized disclosure of data, resulting in a high impact on confidentiality without affecting integrity or availability.

Impact

For European organizations, the impact of CVE-2025-42904 is primarily on confidentiality, as sensitive information such as passwords or other confidential data may be exposed to authenticated users who should not have access to such details. This can lead to unauthorized data disclosure, increasing the risk of insider threats, privilege escalation, or lateral movement within the network. While the vulnerability does not affect system integrity or availability, the exposure of sensitive credentials or data can facilitate subsequent attacks that compromise these aspects. Organizations relying heavily on SAP Application Server ABAP for critical business processes, including finance, manufacturing, and supply chain management, could face significant operational and reputational risks if sensitive data is leaked. The requirement for authentication limits the attack surface to insiders or compromised accounts, but given the widespread use of SAP in European enterprises, the potential for exploitation remains notable. Additionally, regulatory frameworks such as GDPR impose strict requirements on protecting personal and sensitive data, so unauthorized disclosure could lead to compliance violations and financial penalties.
