Vulnerability Data

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…

more

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require mitigations such as rel="noopener" on external links.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect missing protections on external links through automated or manual checks.

A.8.23 Web filtering partial match
degrades

Web filtering can block or warn on links to untrusted external domains, reducing the attack surface for window.opener abuse.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle processes require design and code reviews that should identify missing rel="noopener" or target="_blank" mitigations.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate explicit handling of external links and window.opener protections.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles include isolation of untrusted content and safe navigation patterns that mitigate opener-based attacks.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require the use of rel="noopener noreferrer" on external links, eliminating the weakness.
