Description

SAP Commerce Cloud allows an unauthenticated attacker to abuse a default authentication client and submit specially crafted input to certain functions lacking sufficient validation. Successful exploitation could enable arbitrary code execution and compromise internal components, resulting in high impact on confidentiality, integrity, and availability of the application.

  "executiveSummary": "SAP Commerce Cloud suffers from an input validation vulnerability that can be exploited by an unauthenticated attacker to achieve arbitrary code execution and compromise internal system components.\nThe vulnerability stems from the misuse or abuse of a default authentication client combined with a lack of sufficient input validation in specific application functions.\nSuccessful exploitation of this flaw yields a severe impact on the confidentiality, integrity, and availability of the affected application and its underlying infrastructure.\nThe attacker capabilities include unauthenticated remote interaction, enabling unauthorized submission of crafted payloads directly to vulnerable application endpoints.\nRisk implications are critical, as full system compromise can lead to data exfiltration, service disruption, and total loss of administrative control over the enterprise environment.\nExploitation requirements are minimal regarding authentication, relying entirely on network accessibility to the default authentication client and the targeted functions lacking input validation.",
  "technicalDetails": "The root cause of the vulnerability resides in insufficient input validation mechanisms implemented within specific functions of SAP Commerce Cloud, which process data originating from a default authentication client.\nThe vulnerable components involve the authentication client handling subsystem and associated application functions that fail to properly sanitize, validate, or restrict input parameters before processing them.\nAuthentication and privilege requirements are absent for the initial attack vector, as the vulnerability explicitly allows unauthenticated remote actors to interact with the default authentication client.\nNetwork exposure is inherent to the application's external-facing services or internal service boundaries where the default authentication client and vulnerable functions are accessible.\nThe attack flow begins when an unauthenticated attacker targets the default authentication client to initiate or relay communications with the backend application logic.\nThe attacker then crafts a specialized input payload designed to exploit the lack of input validation within the targeted functions.\nUpon submission, the application processes the malicious input without adequate bounds checking or sanitization, allowing the payload to traverse vulnerable execution paths.\nPayload behavior involves exploiting internal processing flaws to inject and execute arbitrary code within the context of the application runtime.\nPost-exploitation impact includes full arbitrary code execution, enabling the attacker to compromise internal system components, manipulate application data, escalate privileges, and severely disrupt confidentiality, integrity, and availability."
