Vulnerabilities: October 2025 Highlights
[CVE-2025-42942]Â Cross-Site Scripting (XSS) vulnerability in SAP NetWeaver Application Server for ABAP (SAP Note 3597355Â )
SAP NetWeaver Application Server for ABAP has cross-site scripting vulnerability. Due to this, an unauthenticated attacker could craft a URL embedded with malicious script and trick an unauthenticated victim to click on it to execute the script. Upon successful exploitation, the attacker could access and modify limited information within the scope of victim’s browser. This vulnerability has no impact on availability of the application.
 [CVE-2025-42911] Missing Authorization check in SAP NetWeaver (Service Data Download) (SAP note 3627644)
SAP NetWeaver (Service Data Download) allows an authenticated user to call a remote-enabled function module, which could grant access to information about the SAP system and operating system. This leads to a low impact on confidentiality, with no effect on the integrity and availability of the application
[CVE-2025-42901] Code Injection vulnerability in SAP Application Server for ABAP (BAPI Browser) (SAP note 3652788)
SAP Application Server for ABAP allows an authenticated attacker to store malicious JavaScript payloads which could be executed in victim user’s browser when accessing the affected functionality of BAPI explorer. This has low impact on confidentiality and integrity with no impact on availability of the application.
[CVE-2025-31331] Authorization Bypass vulnerability in SAP NetWeaver (SAP Note 3577131)
SAP NetWeaver allows an attacker to bypass authorization checks, enabling them to view portions of ABAP code that would normally require additional validation. Once logged into the ABAP system, the attacker can run a specific transaction that exposes sensitive system code without proper authorization. This vulnerability compromises the confidentiality.
