CVE-2021-42064 is a critical vulnerability affecting SAP Commerce, specifically when configured to use an Oracle database. This vulnerability allows attackers to execute crafted database queries through a parameterized "in" clause in the flexible search Java API. The risk arises when the parameterized "in" clause accepts more than 1000 values, resulting in potential exposure of the backend database.
The severity of this vulnerability is rated as critical, with a CVSS score of 9.8. This high score underscores the potential impact on organizations, as it allows for unauthorized access and manipulation of sensitive data. Given the nature of the attack vector, which is network-based and of low complexity, organizations must act swiftly to address this flaw.
Organizations should prioritize patching immediately to prevent exploitation. There is currently no public proof of concept or known exploit associated with this vulnerability, but the implications of an attack could be severe, potentially affecting the confidentiality, integrity, and availability of data.
In summary, CVE-2021-42064 poses a significant risk to organizations using affected versions of SAP Commerce. Remediation efforts should focus on implementing available patches and assessing configurations to mitigate the risk of exploitation.
Vulnerability Details
The CVE description indicates that this vulnerability allows attackers to execute crafted database queries due to improper handling of parameterized "in" clauses when more than 1000 values are accepted. This issue exists in SAP Commerce versions 1905, 2005, 2011, and 2105.
The vulnerability is classified under CWE-89, which pertains to SQL injection flaws. The CVSS score of 9.8 reflects the critical nature of the vulnerability and highlights the need for immediate attention from affected organizations.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of input values in the flexible search Java API. Attackers may leverage this flaw by crafting specific queries that exploit the parameterized "in" clause. The attack vector is network-based and requires no authentication or user interaction, making it accessible to a wide range of potential attackers.
The attack complexity is low, as the flaw can be exploited without any advanced skills. The impact on confidentiality, integrity, and availability is high, as successful exploitation can lead to unauthorized access to sensitive data and potentially disrupt operations.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data, which can compromise customer trust and lead to regulatory penalties. The potential blast radius is significant, as the exploitation of this vulnerability could affect multiple systems relying on the compromised database.
Given the critical CVSS score of 9.8, organizations must assess their exposure to this vulnerability and implement necessary mitigations. The urgency assessment based on exploitation potential indicates that organizations should prioritize addressing this vulnerability in their patch management cycles.

Affected Versions
The vulnerability affects the following versions of SAP Commerce: 1905, 2005, 2011, and 2105. Organizations using these versions should implement the latest patches to mitigate this risk. If version information is missing, it is recommended to consider all versions prior to the vendor patch.
Mitigation & Remediation
Organizations should prioritize immediate patching of affected versions. The latest updates from SAP should be applied as soon as possible to address this vulnerability. In cases where patches are not immediately available, organizations should implement configuration changes to limit the number of values accepted in parameterized "in" clauses.
For further security hardening, organizations should consider implementing network controls to restrict access to the database and monitor for any unusual query patterns that could indicate exploitation attempts. Continuous security testing can also help identify any vulnerabilities that may not have been addressed.
More information on effective penetration testing can be found through penetration testing services that validate the effectiveness of remediation efforts.
Detection Guidance
Organizations should monitor logs for indicators of exploitation attempts, which may include unusual database query patterns or spikes in database activity. Behavioral anomalies related to unauthorized data access should also be investigated.
Network signatures indicating potentially malicious queries should be developed to enhance detection capabilities. Regular audits of database access logs can assist in identifying any unauthorized attempts to exploit this vulnerability.
AppSecure Threat Intelligence Insight
