Sap Business Ai Platform Approuter
Monthly
Header injection in SAP Approuter (the Node.js package for SAP Business AI Platform) allows unauthenticated remote attackers to send specially crafted requests that bypass header sanitization, resulting in limited unauthorized information disclosure from internal backend components. All SAP Approuter Node.js package versions below 23.0.0 are affected, with a vendor-released patch available at version 23.0.0. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog; however, the zero-authentication requirement and low attack complexity make it accessible to opportunistic actors targeting exposed SAP BTP deployments.
Path traversal authorization bypass in SAP Approuter (Node.js package, versions prior to 23.0.0) enables a low-privileged authenticated attacker to send specially crafted requests that escape the Approuter's routing authorization controls and reach protected backend destinations beyond their assigned scope. Successful exploitation yields high confidentiality impact - exposure of sensitive backend data - and limited integrity impact through restricted modifications to protected resources, with no effect on availability. No public exploit code or CISA KEV listing has been identified at time of analysis, and exploitation is constrained by high attack complexity per the CVSS AC:H rating.
Session integrity bypass in SAP Approuter (node.js package versions prior to 23.0.0) enables an authenticated low-privilege attacker to hijack another user's session by sending crafted requests that circumvent header integrity verification on certain code paths. Exploitation demands prior out-of-band observation of the target's session values, constraining this to determined, targeted attackers rather than opportunistic mass exploitation. No public exploit code and no CISA KEV listing identified at time of analysis, but successful exploitation yields full read access to the victim's session context with a high confidentiality impact per CVSS.
Login CSRF in SAP Approuter (SAP Business AI Platform, Node.js package < 23.0.0) allows an unauthenticated remote attacker to bind a victim's session to an attacker-controlled identity by tricking the victim into following a crafted link targeting the unprotected authentication flow. The missing CSRF enforcement is a default configuration gap, not a non-default edge case - all deployments running the affected package version are exposed unless they have manually enabled CSRF protection. No public exploit has been identified at time of analysis and no CISA KEV listing exists; EPSS data was not provided.
Improper error condition handling in SAP Approuter (the node.js routing component of SAP Business AI Platform) allows a low-privileged network attacker to cause a partial availability disruption under a non-default configuration. The attack is highly complex, requiring conditions outside the attacker's control, and produces only low availability impact with no confidentiality or integrity loss. No public exploit has been identified at time of analysis, and a vendor patch is available in Approuter node.js package version 23.0.0 and later.
Unbounded memory growth in SAP Business AI Platform (Approuter) allows a low-privileged authenticated attacker to degrade availability by flooding the application with high-volume data while suppressing response consumption. The vulnerability stems from insufficient flow control, classified under CWE-770 (Allocation of Resources Without Limits or Throttling). Confidentiality and integrity are unaffected; the impact is limited to availability, and no public exploit or active exploitation (CISA KEV) has been identified at time of analysis.
Certificate validation bypass in SAP Approuter node.js package (versions prior to 23.0.0) enables a low-privileged network attacker holding a certificate from the same trusted CA with matching subject values to impersonate trusted internal components during certain callback flows. The attack path is constrained by high complexity - the attacker must satisfy specific PKI prerequisites - but successful exploitation yields high integrity impact through component impersonation. No public exploit code or CISA KEV listing has been identified at time of analysis.
Tenant context spoofing in SAP Approuter (node.js package < 23.0.0) allows unauthenticated remote attackers to craft requests that bypass tenant isolation, resulting in limited cross-tenant information disclosure. Exploitation is constrained by High Attack Complexity (AC:H per vendor CVSS), meaning conditions necessary for success are not fully under attacker control. No public exploit has been identified at time of analysis and a vendor patch is available, making this a low-urgency but compliance-relevant issue for SAP BTP multi-tenant deployments.
Denial-of-service in SAP Approuter (SAP Business AI Platform), the node.js routing and authentication gateway for SAP BTP applications, allows remote unauthenticated attackers to crash and restart the component by sending specially crafted input under specific runtime conditions. All versions of the SAP Approuter node.js package prior to 23.0.0 are affected, with high availability impact and no confidentiality or integrity exposure. No public exploit has been identified at time of analysis, and SAP has released a patch via Security Note 3786038.
Insufficient authorization enforcement in the WebSocket layer of SAP Approuter (node.js package < 23.0.0) allows a low-privileged authenticated attacker to reach functionality that should be access-controlled. Successful exploitation yields high confidentiality impact - exposure of sensitive data routed through the Approuter - and limited data modification capability, with no effect on availability. No public exploit code has been identified and the vulnerability is not listed in CISA KEV; however, a vendor-released patch is available and should be prioritized for SAP BTP environments.
Token content validation bypass in SAP Approuter (node.js package < 23.0.0) enables an unauthenticated remote attacker to exfiltrate sensitive credential material to an attacker-controlled destination by submitting a specially crafted token. The flaw, classified as CWE-601 (Open Redirect), exploits insufficient URL or destination validation within the Approuter's token-processing logic under specific non-default configurations, yielding high confidentiality impact and low integrity and availability impact. No public exploit or active exploitation is confirmed at time of analysis; vendor patch is available via SAP Approuter 23.0.0 per SAP Security Note 3786038.
