01

What, why and how

SAP Fiori (Launchpad) is vulnerable to Reverse Tabnabbing vulnerability due to inadequate external navigation protections for its link (<a>) elements. An attacker with administrative user privileges could exploit this by leveraging compromised or malicious pages. While administrative access is necessary for certain configurations, the attacker does not need the administrative privileges to execute the attack. This could result in unintended manipulation of user sessions or exposure of sensitive information. The issue impacts the confidentiality and integrity of the system, but the availability remains unaffected.

What

SAP Fiori (Launchpad) is vulnerable to Reverse Tabnabbing vulnerability due to inadequate external navigation protections for its link (<a>) elements. An attacker with administrative user privileges could exploit this by leveraging compromised or malicious pages. While administrative access is necessary for certain configurations, the attacker does not need the administrative privileges to execute the attack. This could result in unintended manipulation of user sessions or exposure of sensitive information. The issue impacts the confidentiality and integrity of the system, but the availability remains unaffected.

Why

The web application produces links to untrusted external sites outside of its sphere of control, but it does not properly prevent the external site from modifying security-critical properties of the window.opener object, such as the location property.

How

An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may obtain information outside the intended access boundary.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Use of Web Link to Untrusted Target with window.opener Access → obtain information outside the intended access boundary
Attack surface
Network
Privileges required
High: elevated access is required
User interaction
Required interaction required
Attack complexity
Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-1022

CWE-1022: Use of Web Link to Untrusted Target with window.opener Access. The web application produces links to untrusted external sites outside of its sphere of control, but it does not properly prevent the external site from modifying security-critical properties of the window.opener object, such as the location property.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:N

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVNetworkAttack vector: The vulnerable component can be reached over a network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRHighPrivileges required: The attacker needs elevated or administrative privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.SUnchangedScope: The security impact remains within the vulnerable component's authority.CLowConfidentiality impact: A successful attack can cause a limited loss.ILowIntegrity impact: A successful attack can cause a limited loss.ANoneAvailability impact: No direct loss is represented by this metric.
Post-exploitation / living off the land
No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.

NCSC-NL · Dutch · NCSC-2025-0275Kwetsbaarheden verholpen in SAP producten

De kwetsbaarheden bevinden zich onder andere in de RMI-P4 module en de SAP NetWeaver AS Java platform. De kwetsbaarheid met kenmerk CVE-2025-42944 betreft een deserialisatieprobleem dat kan worden misbruikt door niet-geauthenticeerde aanvallers, wat kan leiden tot willekeurige OS-commando-executie. Dit bedreigt de vertrouwelijkheid, integriteit en beschikbaarheid van de applicatie. De kwetsbaarheid met kenmerk CVE-2025-42922 stelt geauthenticeerde niet-administratieve gebruikers in staat om willekeurige bestanden te uploaden via de Deploy Web Service-functie. Dit kan ook leiden tot compromittering van systeemvertrouwelijkheid, integriteit en beschikbaarheid.

Official advisory
NCSC-NL · Dutch · NCSC-2025-0245Kwetsbaarheden verholpen in SAP producten

De kwetsbaarheden omvatten onder andere het omzeilen van autorisatiecontroles, Cross-Site Scripting (XSS) en een Directory Traversal kwetsbaarheid. De aanwezigheid van Cross-Site Scripting (XSS) en CRLF-injectie kwetsbaarheden stelt aanvallers in staat om sessies te manipuleren en gevoelige informatie te compromitteren. Van de kwetsbaarheid met kenmerk CVE-2025-42957 wordt gemeld dat deze beperkt actief is misbruikt. Misbruik vereist voorafgaande authenticatie en er is geen publieke Proof-of-Concept-code (PoC) of exploit beschikbaar. Maar deze kwetsbaarheid stelt een kwaadwillende wel in staat om volledige controle over het kwetsbare systeem te krijgen.
