CVE-2022-41215 is a security vulnerability classified under CWE-601 (Open Redirect) affecting SAP SE's SAP NetWeaver ABAP Server and ABAP Platform. This vulnerability arises due to insufficient validation of URLs within the affected SAP products, specifically versions 7.00, 7.01, 7.02, 7.31, 7.40, 7.50, 7.51, 7.52, 7.53, 7.54, 7.55, 7.56, 7.57, 7.89, 7.90. An unauthenticated attacker can exploit this flaw by crafting malicious URLs that redirect legitimate users to attacker-controlled websites. Because the redirection mechanism does not properly validate or restrict the destination URL, users may be unknowingly redirected to phishing sites or other malicious domains. This can lead to the disclosure of sensitive personal information, such as login credentials or other confidential data, if users interact with the malicious site. The vulnerability requires no authentication but does require user interaction (clicking or following the malicious link). The CVSS v3.1 base score is 4.7 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, but user interaction is necessary. The scope is changed, indicating that the vulnerability affects components beyond the initially vulnerable component. The impact is limited to confidentiality (partial loss), with no integrity or availability impact. No known exploits in the wild have been reported as of the publication date (November 8, 2022). This vulnerability is particularly relevant for organizations using SAP NetWeaver ABAP Server and ABAP Platform in their enterprise resource planning (ERP) or business process management systems, as these platforms are widely used in large enterprises globally, including Europe.

For European organizations, the impact of CVE-2022-41215 can be significant in terms of user trust and data confidentiality. SAP NetWeaver ABAP Server and ABAP Platform are core components in many large enterprises, including manufacturing, finance, public sector, and utilities across Europe. An open redirect vulnerability can be leveraged in phishing campaigns targeting employees or partners, potentially leading to credential theft or unauthorized access to corporate resources. While the vulnerability itself does not allow direct system compromise or data manipulation, the resulting phishing or social engineering attacks can facilitate further intrusions or data breaches. This is especially critical for organizations subject to strict data protection regulations such as GDPR, where leakage of personal data can lead to regulatory fines and reputational damage. Additionally, the changed scope of the vulnerability implies that the impact could extend beyond the immediate SAP component, possibly affecting integrated systems or services relying on SAP authentication or workflows. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers often weaponize such vulnerabilities once disclosed. Therefore, European organizations using the affected SAP versions should consider this vulnerability a medium risk that requires timely remediation to prevent exploitation in targeted phishing or social engineering attacks.

1. Apply official SAP patches or updates as soon as they become available for the affected SAP NetWeaver ABAP Server and ABAP Platform versions. Monitor SAP Security Notes and advisories regularly for patch releases related to CVE-2022-41215. 2. Implement strict URL validation and filtering at the application or web server level to detect and block suspicious redirect URLs. This can include whitelisting allowed redirect domains or using web application firewalls (WAF) with custom rules to prevent open redirects. 3. Educate users and employees about the risks of phishing attacks, emphasizing caution when clicking on links, especially those received via email or external sources. 4. Review and audit SAP system configurations to identify any custom or third-party applications that might exacerbate the vulnerability or bypass existing controls. 5. Employ multi-factor authentication (MFA) for SAP user access to reduce the risk of credential compromise resulting from phishing. 6. Monitor logs and network traffic for unusual redirect patterns or access to known malicious domains. 7. Coordinate with incident response teams to prepare for potential phishing campaigns exploiting this vulnerability, including rapid detection and containment strategies. 8. If immediate patching is not feasible, consider temporary mitigations such as disabling or restricting the vulnerable redirect functionality or isolating affected SAP components from direct internet exposure.
