Security News > 2021 > February > Critical Vulnerability Patched in SAP Commerce Product
SAP has released seven new security notes on February 2021 Security Patch Day, including a Hot News note that addresses a critical flaw in SAP Commerce.
Tracked as CVE-2021-21477 and featuring a CVSS score of 9.9, the critical issue could be abused for remote code execution, SAP explains in its advisory.
The vulnerability impacts SAP Commerce if the rule engine extension is installed.
While making modifications to ruleContent should normally be allowed for highly privileged users only, a misconfiguration shipped with SAP Commerce resulted in lower-privileged users and user groups being allowed to change ruleContents.
"This enables unauthorized users to inject malicious code into these scripts resulting in a strong negative impact on the application's confidentiality, integrity and availability," researchers with Onapsis, a firm that specializes in securing Oracle and SAP applications, explain.
SAP has addressed the bug by changing the default permissions for new SAP Commerce installations, but additional manual remediation steps are needed for existing installations.
