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: 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 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

To mitigate CVE-2025-42882, European organizations should implement the following specific measures: 1) Conduct a thorough audit of user privileges within SAP NetWeaver systems to ensure that only authorized personnel have access to sensitive function modules, especially those capable of retrieving system environment information. 2) Apply strict role-based access controls (RBAC) and enforce the principle of least privilege to minimize the number of users with execution rights on critical ABAP function modules. 3) Monitor and log all executions of sensitive function modules and review logs regularly for anomalous or unauthorized activity. 4) Implement network segmentation and restrict access to SAP NetWeaver Application Server interfaces to trusted networks and users only. 6) Employ SAP-specific security tools and configurations, such as SAP Solution Manager and Security Notes, to detect and remediate authorization weaknesses. 7) Conduct regular penetration testing and vulnerability assessments focused on SAP environments to identify and address similar authorization issues proactively. These targeted actions go beyond generic advice by focusing on SAP-specific controls and monitoring.

Description

Due to a missing authorization check in SAP NetWeaver Application Server for ABAP, an authenticated attacker with basic privileges could execute a specific function module in ABAP to retrieve restricted technical information from the system. This disclosure of environment details of the system could further assist this attacker to plan subsequent attacks. As a result, this vulnerability has a low impact on confidentiality, with no impact on the integrity or availability of the application.

Impact

For European organizations, the impact of CVE-2025-42882 is primarily related to the potential exposure of sensitive system environment information within SAP NetWeaver Application Server for ABAP. This information leakage can aid attackers in mapping the system architecture, identifying additional vulnerabilities, or crafting sophisticated attacks such as privilege escalation, lateral movement, or targeted malware deployment. Although the direct confidentiality impact is low and there is no effect on integrity or availability, the vulnerability increases the attack surface and risk profile of SAP environments. Given SAP's widespread use in critical sectors such as manufacturing, finance, utilities, and public administration across Europe, exploitation could indirectly lead to significant operational disruptions or data breaches if leveraged as part of a multi-stage attack. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often weaponize such reconnaissance vulnerabilities over time. Organizations relying heavily on SAP for core business processes should consider this vulnerability a potential enabler for more damaging intrusions.

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.
