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: 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.

Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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.

AI-suggested

Monitor SAP Security Advisories closely and apply official patches or updates as soon as they become available for the affected SAP NetWeaver versions.
Implement strict session management controls, including session timeouts and re-authentication for sensitive transactions, to reduce the risk of session hijacking or misuse.
Deploy anti-CSRF tokens on all transaction forms and validate them server-side to ensure requests originate from legitimate user sessions.
Enforce the principle of least privilege by reviewing and tightening user permissions within SAP to minimize the potential impact of compromised accounts.
Conduct regular security awareness training focused on credential protection and phishing prevention to reduce the risk of attacker authentication.
Utilize SAP’s security audit logs and monitoring tools to detect unusual transaction patterns or unauthorized access attempts promptly.
Consider implementing multi-factor authentication (MFA) for SAP user logins to add an additional layer of defense against credential compromise.
Review and harden network segmentation and access controls to limit exposure of SAP systems to only trusted internal networks and users.
Test and validate all mitigations in a controlled environment before deployment to ensure they do not disrupt legitimate business processes.

Description

CVE-2025-42908 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability affecting SAP NetWeaver Application Server for ABAP versions including 7.53, 7.54, 7.77, 7.89, 7.93, and 9.16. An authenticated attacker can exploit this flaw to bypass the initial transaction screen and authorization checks by initiating transactions directly via the session manager. This enables unauthorized execution of actions and transactions that normally require specific permissions, compromising system confidentiality and integrity. The vulnerability does not impact system availability and requires the attacker to have valid user credentials.

Impact

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive business data and processes managed through SAP NetWeaver Application Server for ABAP. Unauthorized transaction execution could lead to data manipulation, unauthorized financial transactions, or exposure of confidential information. Given SAP's widespread use in critical sectors such as manufacturing, finance, utilities, and government across Europe, exploitation could disrupt business operations and damage trust. Although availability is not impacted, the breach of authorization controls undermines compliance with data protection regulations like GDPR, potentially leading to legal and financial penalties. The requirement for attacker authentication limits exposure to insider threats or compromised credentials but does not eliminate risk, especially in environments with weak credential management or phishing vulnerabilities. The absence of known exploits currently provides a window for proactive mitigation, but organizations should act swiftly to prevent potential targeted attacks. The impact is particularly acute for organizations with complex SAP landscapes and high-value transactions, where unauthorized actions could have cascading operational and reputational consequences.

Compound weaknessLikelihood of exploit: MediumCWE Top 25 (2025): #3OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation
Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
Architecture and Design
Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
