CVE-2022-41207: CWE-601 in SAP SE SAP Biller Direct
SAP Biller Direct allows an unauthenticated attacker to craft a legitimate looking URL. When clicked by an unsuspecting victim, it will use an unsensitized parameter to redirect the victim to a malicious site of the attacker's choosing which can result in disclosure or modification of the victim's information.
AI Analysis
Technical Summary
CVE-2022-41207 is a medium-severity vulnerability classified under CWE-601 (Open Redirect) affecting SAP SE's SAP Biller Direct product, specifically versions 635 and 750. The vulnerability allows an unauthenticated attacker to craft a URL that appears legitimate but contains an unsanitized parameter used for redirection. When an unsuspecting user clicks this malicious URL, they are redirected to an attacker-controlled site. This redirection can facilitate phishing attacks, credential harvesting, or the delivery of malware by exploiting the trust users place in SAP Biller Direct URLs. The vulnerability does not require any authentication, which broadens the attack surface, but it does require user interaction in the form of clicking the malicious link. The CVSS 3.0 base score is 6.1, indicating a medium severity level, with the vector AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. This means the attack can be launched remotely over the network with low attack complexity, no privileges required, but user interaction is necessary. The scope is changed (S:C), indicating that the vulnerability affects resources beyond the vulnerable component, potentially impacting confidentiality and integrity but not availability. No known exploits in the wild have been reported to date, and no official patches are linked in the provided data, suggesting that mitigation might rely on configuration or workaround measures until patches are available. The vulnerability primarily impacts the confidentiality and integrity of victim information by enabling attackers to redirect users to malicious sites, potentially leading to information disclosure or modification through social engineering or subsequent attacks.
Potential Impact
For European organizations using SAP Biller Direct, this vulnerability poses a significant risk of social engineering attacks that can lead to credential theft, unauthorized access, or malware infections. Given that SAP Biller Direct is used for billing and payment processes, successful exploitation could undermine trust in financial transactions and lead to financial fraud or data breaches involving sensitive customer or corporate financial information. The open redirect can be leveraged in targeted phishing campaigns against employees or customers, increasing the likelihood of successful compromise. The medium severity rating reflects that while the vulnerability does not directly compromise system availability or require authentication, the potential for confidentiality and integrity breaches can have cascading effects on business operations, regulatory compliance (e.g., GDPR), and reputational damage. Organizations in sectors with high financial transaction volumes or those subject to strict data protection regulations are particularly at risk. Additionally, the changed scope indicates that the impact could extend beyond the SAP Biller Direct component, potentially affecting integrated systems or user credentials if attackers leverage the redirect to facilitate further attacks.
Mitigation Recommendations
1. Implement strict URL validation and sanitization on all parameters used for redirection within SAP Biller Direct to prevent open redirect exploitation. 2. Configure web application firewalls (WAFs) to detect and block suspicious redirect URLs or patterns associated with this vulnerability. 3. Educate users and employees about the risks of clicking on unsolicited or suspicious links, especially those appearing to originate from SAP Biller Direct. 4. Monitor logs for unusual redirect activities or spikes in URL redirection attempts that could indicate exploitation attempts. 5. If possible, restrict or disable the use of open redirect parameters in SAP Biller Direct until an official patch is released. 6. Employ multi-factor authentication (MFA) on SAP Biller Direct access points to reduce the risk of credential compromise following phishing attacks. 7. Coordinate with SAP support channels to obtain and apply any available patches or security updates promptly. 8. Use email filtering solutions to detect and quarantine phishing emails that might exploit this vulnerability. 9. Conduct regular security assessments and penetration testing focused on URL redirection and input validation controls within SAP Biller Direct implementations.
