Integrity: Low
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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on 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.

What to do

AI-suggested

To mitigate CVE-2025-42883, European organizations should implement the following specific measures: 1) Restrict administrative privileges strictly to trusted personnel and enforce the principle of least privilege to minimize the number of users who can upload files. 2) Monitor and audit all file upload activities within the SAP Migration Workbench to detect anomalous or unauthorized uploads promptly. 3) Implement external malware scanning solutions integrated with SAP file upload processes to ensure all uploaded files are scanned regardless of uploader privileges. 4) Apply SAP security patches and notes as soon as they become available for this vulnerability or related components. 5) Harden SAP system configurations by disabling unnecessary file upload functionalities if not required for business processes. 6) Conduct regular security assessments and penetration testing focused on SAP environments to identify and remediate similar weaknesses. 7) Educate SAP administrators on the risks associated with file uploads and the importance of following secure operational procedures. 8) Employ network segmentation and access controls to limit the potential impact of compromised SAP components. These targeted actions go beyond generic advice by focusing on administrative control, monitoring, and integration of malware scanning specifically for the Migration Workbench file upload process.

Description

Migration Workbench (DX Workbench) in SAP NetWeaver Application Server for ABAP fails to trigger a malware scan when an attacker with administrative privileges uploads files to the application server. An attacker could leverage this and upload a malicious file into the system. This results in a low impact on the integrity of the application.

Impact

For European organizations, the impact of CVE-2025-42883 is primarily on the integrity of SAP systems. Since exploitation requires administrative privileges, the vulnerability does not directly increase the risk of initial compromise but can facilitate the deployment of malicious files once an attacker has gained high-level access. This could lead to further compromise of SAP environments, potentially affecting business-critical processes such as finance, supply chain, and human resources. The lack of malware scanning on uploaded files increases the risk of malware persistence or the introduction of backdoors. While confidentiality and availability are not directly impacted, the integrity compromise could indirectly lead to data manipulation or disruption of operations. Organizations in sectors heavily reliant on SAP, such as manufacturing, energy, telecommunications, and public administration, may face operational risks if attackers exploit this vulnerability. Additionally, regulatory compliance frameworks in Europe, including GDPR, require maintaining system integrity, so failure to address this vulnerability could have compliance implications.

The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
Architecture and Design
Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.
Architecture and Design · Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
Architecture and Design
Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically.
