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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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-2025-42968, European organizations should implement the following specific measures: 1) Enforce strict access controls and least privilege principles for SAP users, ensuring that only necessary users have access to SAP NetWeaver systems and that their permissions are tightly scoped. 2) Monitor and audit SAP user activities, especially calls to remote-enabled function modules, to detect anomalous or unauthorized access patterns. 3) Apply SAP security notes and patches promptly once available, as SAP typically releases fixes for such vulnerabilities. 4) Use SAP’s security configuration tools to review and harden RFC permissions and restrict access to sensitive function modules. 5) Implement network segmentation to isolate SAP systems from less trusted network zones, reducing the risk of credential compromise spreading. 6) Employ multi-factor authentication (MFA) for SAP user logins to reduce the risk of credential misuse. 7) Conduct regular security assessments and penetration tests focusing on SAP environments to identify and remediate authorization weaknesses. These steps go beyond generic advice by focusing on SAP-specific controls and operational monitoring tailored to the nature of this vulnerability.

Description

SAP NetWeaver allows an authenticated non-administrative user to call the remote-enabled function module which could grants access to non-sensitive information about the SAP system and OS without requiring any specific knowledge or controlled conditions. This leads to a low impact on confidentiality with no effect on integrity or availability of the application.

Impact

For European organizations, the impact of CVE-2025-42968 is primarily related to information disclosure. While the data accessed is non-sensitive, it can provide attackers with valuable insights into the SAP system configuration and operating system environment. This reconnaissance information can be leveraged to craft more effective attacks, such as privilege escalation or lateral movement within the network. Given the widespread use of SAP NetWeaver in European enterprises across sectors like manufacturing, finance, and public administration, the vulnerability could facilitate targeted attacks against critical business infrastructure. However, since the vulnerability does not affect integrity or availability, direct disruption or data manipulation risks are low. The requirement for authenticated access limits exposure to insiders or attackers who have already compromised user credentials, emphasizing the need for strong identity and access management. Overall, the vulnerability represents a moderate risk that could be a stepping stone in a multi-stage attack chain, particularly in environments where SAP systems are integrated with other critical business applications.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
